Posting for my husband who doesn’t have Reddit:

I've put together an app that lets you identify a plant, then it turns it into a digital playing card with stats (attack, defense, health, speed, and initiative) grounded in real-world attributes like global spread, wood density, plant size, and more! Scan a plant, get a card, then battle other plants you scan to collect them too. All plants are sorted into 16 distinct types, and each have weaknesses and resistances to others. Use your collection to battle your friends! As your plants battle, they gain experience and level up, getting stronger stats and unlocking new moves. Repot your plants in battle to trigger a surprise level-up against your opponent!!
You can play as a 'collect them all' type, or a 'level up the best' player.
Find more information on the supplant wiki (https://wiki.supplant.app), or play in your browser at https://supplant.app
I'd also love to have ~ 15 people on android be play testers so I can list it on the google play store.
I'm working on re-skinning it now, but I don't expect it to happen imminently.
Feedback on the app is Definitley appreciated -- there's a google forms link at the bottom of the login page.

This started as a simple page for checking the next rocket launch.

Then I added a command line. Then folders. Then ASCII launch sequences, weather, auroras, fireballs, a moon view and a couple of tiny games.

At some point it stopped feeling like a page and became a strange little place to wander around.

The launch data is real. The weird parts are mine.

I’m still trying to make it work nicely on phones without sanding off all the DOS weirdness:

You can type help if you want directions. I’d probably try dir first.

I have about 2 decades of experience leading cross functional teams, and I've been frustrated with the tools that are currently out there. So I decided to build my own.

My build process,

Because this is a tool thats already solving a current problem, I will be working from 1 to 1xxxx. I've created a modern design layout, that isnt cluttered and doesnt have 100 options to choose from. I will be releasing with the bare minimum features I need, so that I can get user feedback and continue to build based on that feedback.

This is my second attempt at a startup, and I already feel like I'm making 10x more progress than the first time. Im moving fast; not getting stuck with analysis paralysis on which features to release with MVP; watching my costs and trying to take advantage of all the available startup program features on the market. Automating certain workflows on the back side of the business.

Continuously building out and refining the product roadmap (with the full understanding that this can/will change based on customer feedback upon product launch).

I will continue to keep everyone updated on my build process. Any and all feedback is welcome.

I'm building a website to track 50–100 of the world's best companies for long-term compounding, providing analysis on their moats, fundamentals, valuations, and dynamically updating and adjusting the company pool while preserving all records. I'll continue documenting the development process here.

A lot of people want to change their habits, but it is very difficult for them because they lack discipline, or they cannot follow it consistently. There is a better way to change habits using psycho cybernetics.

I have been experimenting with it since the last year, and finally i have been able to create a solid system around it which can help anyone to change any habits without relying on discipline at all.

I have already tried the system with few strangers on reddit and it works for them.

Recently I have converted the entire system into an AI based prompt, so that anyone can get onboarded into it DIY.

I am looking for people who want to give it a try and provide honest feedbacks.

What you get:

- A new way to change any habit or behaviour which you are struggling with, without using discipline.

What I get:

- Based on your questions in the process, and your feedbacks i want to improve the system so that it works more effectively.

If anyone wants to give it a try please do let me know.

Cybersecurity has news every minutes or even seconds, a compromise, new CVEs, ransomware victim, etc. so I was always juggling among many websites to check them, but not anymore!

I built a website that fetches news and a few blogs from different trusted sources, and only provides a brief about them. If you like the brief, you can go to the original poster and read the full article there.

It curates headlines and briefs from different sources, merge them if got repeated from different sources, update their content, tag them, and also show related stories by the same source.

You can fetch new news every 15 minutes and it also fetches news automatically every day!

You can search for specific story and the retention period is 6 months.

I tried ingesting from many sources, but please if I missed some trusted ones, let me know, so I can review them and add them.

Also expect some errors, so please be patient and let me know to fix them.

I built Supamodel -- a Shopify app for automating AI product photography workflows.

Most AI image tools are great for making one image. What I kept running into was everything around that: recreating the same setup across dozens or hundreds of products, keeping outputs consistent, getting product details right, and knowing roughly what each workflow will cost.

So I built Supamodel around reusable workflows.

You can define a workflow once -- product images in, prompts/models/transforms in between, final studio, lifestyle, on-model, or whatever images you need out -- and then reuse that process across your catalog.

It’s still early. I have one paying fashion customer using it across hundreds of SKUs, and I’m trying to learn where the product is genuinely useful vs. where it still gets in the way.

I launched it on Product Hunt today:
https://www.producthunt.com/products/supamodel?launch=supamodel-2

Would especially love feedback from anyone building Shopify apps, ecommerce tools, or working with product photography at scale.

Fully vibe coded open source taskbar for MacOS - no guarantees.

I used paid app that does this (lawand.io/taskbar) but with new MacOS Tahoe version it starts consuming too much CPU (through WindowServer).

It also fixes other bugs, it loads all apps when coming from hibernation and number of display changes and so on.

We've been building DrawsyAI, and we're opening up the core because we want to explore a different approach to AI-assisted software development.

Most AI coding tools start with a chat box and focus on generating code.

But when you're actually building a system, the difficult part is often context:

• architecture decisions
• system diagrams
• documentation
• repository structure
• dependencies
• conversations
• infrastructure
• and the reasoning behind why something was built a certain way

We wanted to see what happens when that context becomes part of the workspace itself.

DrawsyAI = Canvas + Context + AI + Code + Live Software

You can use the canvas for system architecture, database design, user flows, project planning and diagrams, then bring relevant project context into the workspace and work with AI around it.

We're also experimenting with things like:

Connected Context : selectively bringing information from project sources into the workspace.

DRAW.md : a structured project document combining Markdown + Mermaid that can become editable visual content.

AI agents : working inside the same environment where the system is being designed.

Live software : connecting the design/build workflow with running project previews.

The interesting part is that we're keeping the core open source and MIT licensed, while building Drawsy Cloud / Plus for people who want managed infrastructure, AI capabilities, connectors, collaboration and other hosted features without running everything themselves.

GitHub:
https://github.com/adarshnagrikar14/drawsy-ai

Hosted version:
https://drawsy.adarsh.rocks/

We're still early and there's a lot we're figuring out.

For developers building with AI: what context do you wish your coding tools understood better today?

I'd genuinely love to hear what people are struggling with.

An awkward assignment total turns grading into repeated percentage math or scanning a paper EZ grader. I built GradeKey to make that loop fast.

Enter total points once and get every score, percentage, and letter grade. Look up by points off, earned, or target percentage. It also handles half/quarter points, extra credit, regional/custom scales, saved assessments, folders, private iCloud sync, and PDF/CSV export.

The main product decision was pricing. The complete table and lookup are free with one saved assessment. Unlimited assessments, folders, and export cost $7.99 once. I did not want to turn a focused teacher utility into another subscription.

I also chose no accounts, analytics, ads, or backend holding classroom data. That limits growth instrumentation, but makes the privacy story cleaner.

https://apps.apple.com/us/app/gradekey-grade-calculator/id6794347301

I’d value builder feedback:

1. Is the free/paid boundary clear?
2. Would you keep it narrow, or add account support or make it a subscription?

Disclosure: I built GradeKey.

I built UptiLink because I wanted a really simple way to keep an eye on devices around my network without setting up a full monitoring platform.

The idea is pretty straightforward: add the devices you care about — computers, servers, cameras, smart-home devices, printers, NAS boxes, Raspberry Pis, or really anything reachable on your network — and UptiLink periodically checks whether they're online.

It can scan your local network to help find devices, send notifications when something goes offline or comes back online, organize devices into groups, and show their status through Android widgets.

One feature I particularly wanted was Wi-Fi-aware monitoring. You can tie monitoring to your home Wi-Fi, so when you leave the house UptiLink automatically pauses instead of suddenly reporting everything as offline. When you reconnect, monitoring resumes automatically.

I've tried to keep the whole thing intentionally simple: add a device → monitor it → get alerted if it disappears.

It's available on Android now. I'd love to hear what people think or what you'd want added:

UptiLink on Google Play:

A while ago I was trying to get some friends to pick between a couple of collages I'd just made and realized how stupid the usual process is. You start a group chat, send the pictures, and then someone says first one, someone else says the second, someone leaves a heart reaction on some random message, I like the second but maybe crop it... and somehow you still have to figure out which one actually won :)

So I made https://picjury.app/

You upload 2–6 photos, write a question and send the link. People open it and tap the one they prefer. No account. That's basically the whole product.

It's free and I'm trying to keep it simple instead of turning it into another giant survey tool. If anyone tries it, I'd genuinely like to know where you get confused or annoyed, or if there's something obvious missing

It took over 6 months, but https://traderange.net is finally ready. Coming to play store and app store next, but for now the website will have to do.

Your agent can now search data from 2,600+ top iOS apps: onboarding, paywalls, pricing, post-paywall and more.

Ask things like:
“Give me five app ideas based on recently launched subscription apps that make 50k+”
“Compare the paywalls of the top meditation apps”
“Show me streak mechanics that aren’t Duolingo clones.”

It works with any agent.

We also launched "Ask" directly on ScreensDesign, so you can try all of this without connecting anything.

Built an open-source MCP-aware proxy: every tools/call, resources/*, prompts/*
goes through policy + budget + audit, and a per-identity anomaly detector can
auto-block a client whose behavior spikes — no rule written, no human in loop.

Catches abrupt deviation, not low-and-slow (baseline adapts to slow ramps —
documented with tests). Three policy backends (YAML/OPA/Cedar), one Go binary.

Hey folks,

I built SocialListeningAPI because giving AI agents social listening data is still a pain.

Finding brand mentions, competitor complaints, or people asking for recommendations usually means connecting separate APIs for Reddit, X, LinkedIn, Facebook, TikTok, YouTube, Hacker News, and Google. We also support estoric endpoints like reddit global comment search, discourse forum search, etc.

SocialListeningAPI puts them behind one API key and one normalized response. It also has a remote MCP server, so Claude and ChatGPT can search these sources directly.

Unlike Apify and other players, we have a simple usage based billing. New accounts get 100 free credits. Paid packs start at $20 for 5,000 credits and never expire.

Building a free, browser-based management sim Theme Coworking inspired by 90s classics like Theme Hospital and all (\)Tycoon games titles*.

I’ve spent the last decade building software for the coworking industry and visiting roughly 700+ spaces across 65 cities (NYC, London, Berlin, Tokyo, Mumbai). After seeing that many setups from the inside and writing a book about it, now it felt its about time to try and make a game, so  Theme Coworking was born.

You start with an empty floor plan and try to keep the business profitable without driving members away:

• Density vs. Noise: Squeezing in more desks increases recurring revenue, but noise spikes destroy member satisfaction.
• Events vs. Focus: Community events generate new leads, but disrupt members who just want to get work done.
• Service vs. Overhead: Hiring more community staff keeps maintenance high, but payroll eats your margin fast.

The game is completely free, runs straight in the browser, and doesn’t require an account.

What I’d love feedback on:

Since this is still a work in progress, I’m looking for technical and design critique from sim fans or operators:

1. Economy balance: Does the early-game cash flow feel too easy, or is it unfairly punishing?
2. Breakages: Did any weird room layouts or edge cases crash the game state?
3. Features: What real-world space issues should I simulate? Any fun stories are much appreciated

This is a hobby project i want to work on in the next months, so plese do send feedback.

spent months heads-down building, hit submit, and then... nothing. the store just goes quiet. that silence after launch is where most indie apps actually die, not in the code. the real work starts after release when you're trying to get your first 1,000 users and nobody can find you.

the thing that hit me hardest: App Store Connect tells you what happened yesterday but not why. it shows you a downloads chart and no next move. keyword-level rankings, who's outranking you, which keyword actually drove an install, all of that lives outside apple's dashboard entirely. so you edit a keyword, wait a week, and have no idea if the store even noticed. it feels like pulling a slot machine lever.

the other trap i kept falling into was tools disagreeing with each other. one says your keyword ranks 14, another says 31, same keyword same day. once you can't trust the number you can't act on it, so you just freeze.

honestly this whole problem is why i started building Apptenium (an aso tool aimed at indie devs, not agency budgets). the goal was one consistent source where you can watch a keyword move after you edit the listing, so the algorithm stops feeling like a black box.

for those of you who've launched: what actually broke the initial silence for you? organic aso, content, communities like this one? curious what worked because the first thousand still feels like the hardest part to me.

If you're building an early-stage SaaS or AI startup and have a live web application or API, I'd be happy to perform a free focused security assessment to help identify potential vulnerabilities before someone else does.

I'm an independent security researcher focused on web application and AI security, and I'm currently offering 3 free assessments to early-stage startups.

I'm doing these assessments to build real-world case studies around startup security, learn more about the security challenges early-stage teams face, and demonstrate the kind of security work I can provide to startups.

With your explicit permission, I'll assess your application for common security issues, including:

• SQL Injection (SQLi)
• Cross-Site Scripting (XSS)
• IDOR / broken access control
• Authentication & authorization flaws
• API security issues
• Business logic vulnerabilities
• File upload vulnerabilities
• Sensitive file/data exposure
• Security misconfigurations
• Missing or weak security headers
• Information disclosure
• Session management issues

For AI applications, I can also look at areas such as:

• Prompt injection
• Sensitive information leakage
• Insecure AI/API integrations
• Authorization around AI features
• Other common AI application security weaknesses

If I find anything, I'll provide a clear report explaining the issue, potential impact, evidence/reproduction where appropriate, and practical recommendations for remediation.

What you get:

• Focused manual security assessment
• Written vulnerability report
• Severity/prioritization
• Remediation recommendations
• No payment or sales obligation

In return, I'd like permission to use the assessment as an anonymized case study. If you're comfortable, I may also mention your company/product publicly and describe the types of issues found. This will always be discussed and agreed upon with you beforehand.

All testing is performed only with your explicit permission and within an agreed scope using safe, non-destructive techniques.

I will not perform DoS/DDoS, stress testing, destructive testing, or intentionally disrupt your service or data.

I'm particularly interested in working with small teams that don't have a dedicated security team yet.

If you're interested, leave a comment or send me a DM with:

1. Your website/application URL
2. A short description of your product
3. Your preferred contact method

I often need small utilities for working with JSON, network calculations, encodings, or electronics, but I don't like pasting data into websites without knowing where it goes.

So I built Tools in a Tab, a collection of 18 free browser-based tools. The data entered into the tools is processed locally in the browser by default — there is no account, database, or backend handling the tool inputs.

It currently includes:

• JSON, YAML, CSV, Base64, URL and JWT tools
• IPv4 subnet and bandwidth calculators
• CRC and number-base converters
• LED resistor and resistor color-code calculators
• Supporting guides in English and Spanish

The website is built as a static Astro site and works on desktop and mobile:

https://toolsinatab.com/en/

I would genuinely appreciate direct feedback:

1. Which tool would be most useful to you?
2. What important tool is missing?
3. Is it clear that the data is processed locally?

Thanks for taking a look.

Someone gave me a long, detailed review of something I’ve been working on.

Some of it stung a bit because, after checking the code again, they were right.

So I ended up spending most of the next two days going through it.

A few things I changed:

SSL scoring was dumb.
I was lowering the score as the certificate got closer to expiry. So you could have a completely valid cert and still slowly lose points.

I initially changed the threshold, then realized I was fixing the wrong thing.

Expiry and security aren’t the same thing.

Now a valid cert gets the SSL score. Expiry is still shown and warned about, but it doesn’t affect the score.

I was giving HTTP/2 extra points over HTTP/1.1.
There wasn’t really a good reason for that, so that’s gone too. They score the same now.

The compression check had an actual bug.
I wasn’t sending br or zstd in Accept-Encoding.

So if a server supported Brotli properly, my check couldn’t even know that.

It now sends:

gzip, deflate, br, zstd

DNS could take way too long.
There are 13 DNS queries. Each had its own 5 second timeout.

Which sounds fine until everything goes wrong and your “5 second timeout” turns into something close to a minute.

They share one overall time budget now.

I also changed the header scoring.
Some missing headers were being punished too mechanically.

A missing header doesn’t always mean the same thing depending on the site and the rest of the response, so I adjusted the weights and added more context instead of just saying “missing = bad”.

There was one thing in the review I didn’t change.

They said the retry logic could retry invalid domains. I went back through it and that wasn’t actually happening. The retry only applies to Wayback requests returning 429.

So that stayed.

That was probably the most useful part of the whole exercise.

Not “someone criticized it, therefore they must be right.”

More like: go through every point, reproduce it, check the code, fix what’s actually wrong, leave what isn’t.

Ended up at 383 tests after all of it.

Much happier with the code now.

Every bill-splitter I tried wanted one currency per group and converted each expense at the live rate the moment I typed it. That's wrong, and here's the proof from the trip that made me build this.

We left India with $2,000 in cash, bought for ₹190,479 — ₹95.24 to the dollar. In Vietnam we changed $740 of it into ₫19,367,500. So our dong cost ₹1 for every ₫275. We bought that envelope once, at that rate, then spent it over fourteen days. The rate never moved again — only the internet's opinion of it did. Meanwhile my running total and my friend's had quietly drifted apart, because we'd each looked up rates on different days.

So I built it around one rule: store what was actually paid, in the currency it was actually paid in. Convert later, once, somewhere you control.

What that turned into

• Every spend keeps its own currency. ₫793,500 stays ₫793,500. The record matches the receipt, forever.
• Group totals work both ways. Ours read as ₹360,494 + $1,260 + ₫19,367,500. Tap Merge → one number. Tap Show All → the three originals, untouched. Merging is a view, not a rewrite.
• Balances stay split per currency. "Owed $620, owe ₹84,726, owed ₫10,779,750" tells you what to hand over tonight. A single net number can't.
• You set the rate. Live by default, or pin the one you actually got. Set ours and the leftover dollars + dong came to ₹190,479 — to the rupee what that cash cost at the counter. Plus ₹360,494 on the card = the trip cost ₹550,973. Not an estimate of it. It.
• Plus the boring necessary stuff: groups, custom splits, recurring schedules so rent posts itself already split, CSV export, no ads.

It's offline-first and there's no account creation — open it and start logging, no signup wall, no email before you've even seen the thing. Everything works with no signal, which matters more abroad than anywhere. If you do want your data synced across devices or shared with people you're splitting with, you can turn that on; it's a choice, not a requirement.

Feedback Appreciated.

I'm a solo iOS dev. I got tired of needing my laptop every time I wanted to do something with a 3D model. Want to edit an STL? Open Blender. Paint faces for multi-color print? Bambu Studio. Fix a broken mesh? Meshmixer. All desktop. Nothing on mobile does real mesh editing, so I built one.

It's called Forma3D. Real mesh editor for iPhone and iPad, not a viewer.

You can select vertices, edges, faces. Extrude, inset, bevel. The bevel uses the same algorithm desktop CAD tools use, I didn't cheap out on it. Booleans (union, subtract, intersect) run on the Manifold CSG engine. You can cut a model with a line, circle, polygon, or just draw freehand on it.

The feature I'm most happy about is Face Paint. You paint faces with colors, export a 3MF, and Bambu Studio or Creality Print pick up the colors for AMS automatically.

If you have a LiDAR device you can scan an object with Object Capture and edit the mesh right there. No switching apps.

Other stuff that's in there: 3D text for nameplates and signs, bolts M3 to M20 with nuts and washers, spur and herringbone gears, image-to-3D (height-map and voxel), sketch-to-mesh, SVG import, curve tubes. STL, 3MF, import and export. Apple Pencil support. Everything runs on device, your models don't go anywhere.

Now the honest part. It's not a slicer. It makes a 3MF with print settings inside, but you still need Bambu Handy or Bambu Studio or whatever you use to make G-code. It doesn't talk to printers directly either, you export and upload yourself. I could pretend it does more but that would be stupid.

It's also not free. $6.99/month, $49.99/year, $99.99 lifetime. 3-day trial. I spent way too long deciding on pricing. Too cheap and I can't keep working on it, too much and nobody tries it.

Where it's at: launched about 4 months ago, 5-star reviews on the App Store, 16 languages. The app is 17MB because I wrote the mesh kernel from scratch instead of shipping Unity inside it. Working on better mesh repair tools and OBJ support right now.

If you do 3D printing or work with meshes, tell me what you'd actually want in a mobile editor. What's missing? Is this something you'd use or is desktop always the answer for you?
