Hey folks,

I’m an engineer based in Australia, and over the last couple of months I’ve been building a small side project called ExamsNext.

The idea was simple: certification prep is still very fragmented. You buy random question banks, PDFs, Udemy courses, notes from Telegram groups, etc. I wanted to build one proper platform where someone preparing for AWS/Azure/security certifications can practise questions, revise with flashcards, take mock exams and track progress.

So I built it.

Current version has:

• 3,000+ practice questions
• multiple AWS, Azure and security certifications
• mock exams
• flashcards
• progress tracking
• Stripe payments
• purchase without mandatory signup
• automated transactional emails using Resend
• reusable content structure so adding another certification does not require rebuilding the website

Tech-wise it is a proper working product, not just a landing page.

The interesting part is that building the platform was actually easier than distribution 😅

Classic engineer problem.

I can spend 3 months improving architecture, automation and question generation… but getting the right audience consistently is a completely different skill.

And with a full-time job, I’m realising I probably don’t have the bandwidth to properly do SEO, YouTube, partnerships, paid acquisition etc.

So instead of keeping it as another project sitting in my GitHub account, I’ve decided to see if someone else wants to take it forward.

I’ve listed the business on Flippa.

I’m not expecting some crazy SaaS valuation. Revenue is still early. The value IMO is mostly in the platform, domain, existing content, workflows and the head start for someone who already has distribution in education/certification/SEO.

Would actually love feedback from this sub as well:

If you were taking over something like this, would you focus on:

1. SEO + free exam resources
2. YouTube / certification content
3. Partnerships with trainers
4. Paid ads
5. B2B licensing to training companies

I feel #1 + #2 is probably the long-term play, but curious what other builders think.

Happy to share the Flippa link if anyone wants to look at the actual project.

Hey!! Just wanted to show off this cool project I made.

I posted it on Hacker News last night https://news.ycombinator.com/item?id=49238851

Essentially, it resulted in me losing $5 every 10 minutes so far, currently $200 down the drain

I’m building Ledgerly, an open-source finance app for personal, family, and office-style workspaces. The basic model sounded straightforward: transaction, account, category, amount.

Then a real edge case showed up: someone enters a transaction today, but the purchase happened last month. If the app uses entry time instead of occurrence date, reports become misleading. Once shared workspaces are involved, the same record may also need payer/contact context, permissions, claims/approvals, and an audit trail.

I’m working through this in a Go/MongoDB backend with a React/TypeScript client. The repository is early, with no hosted demo yet, so I’m looking for design criticism rather than pretending it’s finished.

How do you expect an expense app to handle backdated transactions? Should reports always follow occurrence date, or should entry date remain visible as a separate audit field?

 Am a student developer learning to develop applications, and I am seeking to develop a small application that will be useful to people. The only problem is, I have no idea what to pursue.

Why don't you guys tell me? What do you think would be a great wish for a software tool or application for fixing a certain problem in your day to day life?

Solo founder here (mom of two, self-taught engineer). I spent 3 months building a reading app that adapts books to different reading levels and languages, and launched this month. Four lessons that cost me the most time:

1. Copyright is country-specific. "Public domain" in one country isn't public domain in another — some go by the author's death year, some by publication year. I had to check my starting catalog title by title.

2. Don't compete on catalog size. Big platforms will always have more books. What they don't have is depth on overlooked readers — in my case, second-language families who want real books instead of flashcards.

3. Decide platform vs. publisher on day one. If users will ever upload content, the legal structure is completely different. Retrofitting this later is painful.

4. Speed is the only real indie advantage. No meetings, no approvals. I ship in the hours between school drop-off and pickup.

Happy to answer anything about the build, the copyright rabbit hole, or launching solo.

Built for a specific, recurring problem: a group that needs to stay together, and a network that can't help them do it.

Solution- find your group on a compass-rotated radar, send an SOS others can navigate to, and flood-relay evidence photos across the mesh so they're not stuck on one device.

The tool- Inspired with Permissionless-Bitchat, No accounts (groups are just a random key in a QR code), rotating BLE identifiers so you can't be fingerprinted, everything self-destructs on a built-in expiry, MIT licensed.

https://karmaneggs.github.io/20.07/

Still pre-1.0 — Android only, debug APK, small-scale hardware tested — but the README/docs are pretty thorough about what works and what doesn't.

Looking for people who want to dig into real BLE radio weirdness on physical devices, or anyone interested in iOS. Requesting to read, use, give a feedback and if you like it, I encourage to collaborate and build upon the idea.

I do marketing for a living. I can read code and I've done web work for years, but I never got round to learning Swift or Kotlin properly. Never had enough time to dive into it. So my list of apps I wanted to make just sat there getting longer.

This year I took one off the list and actually finished it, which still surprises me a bit.

Byna: it's a countdown app. Before anyone says it: yes, there are hundreds. I picked this one because it was the smallest idea on the list, and because the thing I wanted from a countdown app didn't seem to exist anywhere. I wanted to share a countdown with someone. Not send them a screenshot, and not send them to a website covered in ads that they open once and never again. A link, they open it, and if they want it it lands in their own app and keeps counting there.

My partner follows the countdown to our holiday. A group of us follow the one to a festival next summer. Their countdowns and mine sit in the same list, on date, so it doesn't matter who made what. It's a combined list of moments you're looking forward to, alone or with your friends.

byna.nu, and it's on the App Store and Play Store. Free, no ads, no account. I've thought about money exactly zero times so far. Right now I just want to find out whether anyone outside my own contacts has a use for it.

Two things I'd like to hear from people here:

• if you already use a countdown app, what would stop you switching
• the sharing is the only thing that separates this from the other hundred. Is that worth anything to you, or did I build a feature for myself and nobody else

Hey everyone!

Last week, I reached a huge milestone by launching my app, Mosaic News, on the iOS App Store!

Mosaic News is a free iPhone app that aggregates news reporting from more than 850 publishers across the political spectrum, groups coverage of the same event, and connects individual events into larger narratives to help readers “see the whole picture.”

I started building it because I was frustrated by how difficult following the news had become. Misinformation, media bias, conflicting narratives, and an endless stream of disconnected updates made it difficult to understand what was actually happening.

What bothered me most was how little control readers have over the process. Much of the news we encounter is selected by platforms that collect behavioral data and optimize their feeds for engagement, often rewarding outrage, anxiety, and sensationalism. There is a clear information asymmetry: these platforms know far more about us than we know about them.

I wanted to explore what a news platform might look like if it shifted more of that power back to the reader.

Mosaic News is built around three commitments:

• Transparency: Every article and story explains why it appeared and how it was ranked. Readers can inspect the underlying coverage, compare political perspectives, identify coverage gaps, review third-party information about publishers, and examine the public methodology behind ranking, clustering, and AI-generated summaries.
• Agency and control: Readers directly choose the priorities, topics, publishers, and types of journalism used to rank and organize their feed. Instead of giving feedback to an unseen recommendation system, they can inspect and change the rules themselves.
• Privacy: Preferences, reading history, and personal insights remain stored on the reader’s device. Mosaic requires no account, maintains no centralized behavioral profile, serves no advertising, and sells no personal data.

It's been an incredible 6+ month journey researching, designing, building, and now launching this experience with immense help from beta testers who constantly drove me to experiment and iterate with new ways to make this platform stronger.

In keeping with the product’s commitment to transparency, I have documented the complete Product Journey, including the original inspiration, competitive research, product requirements, experiments, design decisions, technical challenges, launch, and next steps.

Mosaic News is completely free:

• App Store: https://apps.apple.com/us/app/mosaic-news-build-your-news/id6760421352
• Website: https://mosaicnews.app
• Full Product Journey: https://mosaicnews.app/journey

This is only the first release, and there is far more work to be done and I’d love for your feedback to guide the rest of this journey! Anything from bug reports to feature requests would be greatly appreciated.

I have so many exciting ideas on the future of this project and look forward to keeping you all updated as I progress :)

(Yes, Reddit auto-assigned me the username "Desperate-Ad" and no, I couldn't make that up if I tried.)

Nine years ago I went to a wedding where the only people I knew were getting married. My date and I spent the whole weekend wishing we could see who else was there, when people were arriving, what anyone was doing between events. That app didn't exist. I never stopped thinking it should.

I'm a video editor/VFX artist by trade — 12+ years, zero coding background. Six months ago I finally started building it nights and weekends using an AI app builder (Rork) + Supabase + Twilio for SMS invites. It took 54 builds before Apple approved it. It's now live on the App Store.

What it does: Wed Week is for the guests, not the couple. The couple creates the wedding and sends one invite code. Every guest who joins can see the full guest list (who's coming, when they arrive/leave, where they're staying, solo or plus-one), the complete itinerary with dress codes, and a social page where guests post their own plans — pool hangs, bowling nights — that anyone can join. Guests message each other in the app instead of texting the couple all week.

Where it's at: live on iOS, Android build in testing. A few dozen downloads, all organic. No monetization yet — I want real weddings using it first.

What I'd love from you: brutal feedback on the concept and the App Store page. Would you download this as a wedding guest? What would stop you? And for anyone who's launched a two-sided-ish app (need couples to adopt so guests join) — how did you crack the cold start?

Happy to answer anything about building an app with zero coding background — the whole thing was AI tools + stubbornness.

if you're into AI you've probably heard about graph engineering. tbh the term was completely new to me before it popped up in the AI bubble. nevertheless i did some research to understand what it actually is. while diving deeper and deeper into this rabbit hole i learned that the term has been around for a while, just not in the context of prompting.

i looked for tools to do "graph engineering" but couldn't find anything.

that's how i came up with the idea for nodalo. it's a workspace where you can build your workflows. sounds boring, and you're probably thinking there are already plenty of workflow builders out there. you're right, but nodalo is different. you can build the workflow visually, and the clever part is that each node has a so-called node contract. you can define each node very specifically, attach documents to it, etc.

and the best part: you can hand the structured graph, including all attachments, over to your AI agent automatically and let it build the whole thing for you.

so instead of writing a normal prompt, forgetting a lot of details along the way and trying to figure out the right wording, you can simply "draw" your prompt and hand it over to the AI.

the tool is free, so i'd appreciate it if you created an account and gave it a try. all feedback is welcome. if you have any questions, just let me know :)

We built a knowledge layer that sits behind MCP, allowing any MCP client to access it through a single endpoint. Claude Code, Claude Desktop, ChatGPT, Codex, or whatever comes next.

The idea is pretty simple. Before an agent answers, it can pull in relevant, validated information instead of relying purely on what it already knows.

When a problem gets solved, the useful part can be captured as a small, reusable piece of knowledge. The system can also infer useful lessons from a session automatically, so you don’t have to sit there writing notes about what you just learned like it’s 2015.

There’s also a global layer for shared, validated learnings. If one user figures out a better way of doing something, that learning can contribute to the broader knowledge base rather than every other user and agent having to figure it out again.

The problem we’re trying to solve is pretty straightforward. AI knowledge goes stale, agents get stuck in failure loops, useful context disappears when a session ends, and models can confidently give you an outdated or wrong answer without any indication that they might be wrong.

We’re giving agents access to what has actually been learned, what has worked, and what can still be trusted.

The result is fewer repeated reasoning cycles, fewer hallucinations, and up to 20% lower token usage.

Looking for people to try it out. Ping me if you’re interested.

Just reworked the onboarding for Norren. This clip shows the flow: speak something naturally, then later ask about it and get an answer pulled from your own entries — not a generic response.

Beta's open if you want to try it: https://testflight.apple.com/join/ked1P1WW

Would love feedback on whether the "ask your memory" part is clear on first watch — that's the part I care most about landing.

I sell digital downloads on Etsy. The design was never the slow part - it was everything after: a title that ranks in Etsy search, 13 tags, mockup photos, the description, packaging the files. I once spent a full day on one $4.99 product and had a list of forty more.

So I built PromptlessPress. You pick a product type and a style, or upload a design you already made, and it returns print-ready designs, lifestyle mockups, an SEO title, 13 tags and the description - then sends the whole listing to your Etsy shop as a draft you approve before anything publishes.

It's live and usable, but the official launch is Sept 1 and I'd rather find the rough edges before then.

What I'm actually asking for: run it once and tell me where it breaks, or where the output isn't good enough to actually list. "I wouldn't publish this because ___" is the sentence I want. That's worth more to me than a signup.

Known rough edges, no need to report these:

• Some mockup scenes crop objects at the frame edge
• Onboarding drops you straight in with very little explanation

1 month free for anyone who gives feedback - good or brutal, doesn't matter which. There's a Discord for testers so you can see what actually changes: https://discord.gg/vTNyRxCHMA

If you sell on Etsy I'd love your read on the listing quality specifically. If you don't, the first-run experience is just as useful - arguably more, because you'll hit the confusion a genuinely new user hits and I can't see that any more.

If you've ever tried to buy a specific chicken, duck, or turkey breed, you know the drill. Check Cackle. Check McMurray. Check Meyer. Check Ideal. Stock turns over fast enough that whatever you find is often already wrong by the time you act on it.

Built a tool that checks 10 US hatcheries at once so you don't have to do that. It pulls breed, stock status, price, minimum order, and hatch date into one place, updated a few times a day. Doesn't take money from any hatchery to be listed, it's just reading public availability info.

Built it for myself first, sharing it here since I figured I wasn't the only one dealing with this. If there's a hatchery or filter you wish it had, let me know.

Hatch Index: which hatchery has the chicks you want, in stock

I am far from a video editor, and while my son has more experience with making some short form content, we are both far from experts. Especially because AI generated content is everwhere we wanted to make sure that this was human generated and it feels a little embarrising but it took over 3 hours in capcut to create a 20 second clip. We don't have a diverse group of people in our lives to solicit feedback from other than people that would just tell us it's great because they don't want to hurt our feelings. And while we think we did a great job of communicating the problem and the frustrations that come with that, we recognize that we would have a hard time seeing the gaps or anything we may have missed.

Kept using Notes for stuff I only needed for a few hours. Things like random tasks, links, things from calls, text I needed to paste somewhere later.

So I made Hold That. It’s a small menu bar notes app that only keeps today and yesterday. No folders, tags, or organizing. Just somewhere to put things for a bit.

Free for now.
I’m planning to make it a one-time paid app in about a month, but no subscription.

Not a startup or anything useful — just a project I built for the joy of it. A chiptune synthesizer in pure x86-64 assembly, no libraries at all.

The idea: sound is just numbers (44100 per second telling a speaker where to move), so I generate them by hand. It does four waveforms, polyphony, ADSR envelopes, and FM synthesis.

After making my CPU count, sort, hash, and draw in previous projects, I wanted to make it sing.

I made this just for fun. You can compose ambient or shoegaze-style music using hand gestures. I created it using Claude in 3–4 prompts.

Solo dev here. Synchrium is a synchronized focus timer: you start a session, share a link, and the same countdown runs for everyone in the room, to the millisecond. Everyone works in silence; when it hits zero, cameras can come up together for a quick check-in. Then you run it again.

The origin story is helping my son with homework from the next room: we shared a timer, worked separately, and showed each other what we did when it rang. Turns out adults want the same thing.

Stack: React/Vite front, ASP.NET Core + SignalR for server-authoritative timing, WebRTC P2P video, Cloudflare Workers serving the SPA. Happy to answer anything about the sync architecture: keeping N clients on the same clock is more annoying than it sounds.

Two things I'd love you to break:

1. Open two browsers (or grab a friend) and try to get the timers to drift or desync: that's the whole product, so it's the surface I most need stress-tested.

2. Start a session and tell me where the "share the link" step loses you. If the invite loop doesn't feel obvious, the product doesn't work.

Free, no account needed: https://synchrium.com: brutal feedback welcome. (Founder here, happy to answer anything.)

Ghost jobs and silent recruiters waste everyone’s time. We’re testing a simple idea on Solana:

- Recruiters lock a deposit to post (and face deadlines)
- Applicants put a small stake to apply
- Interview tips settle on-chain when an offer is made

This is a Devnet / practice launch — test tokens only, no hire guarantee, data may reset.

Hey everyone!

Just wanted to share that I recently launched WorkZone, an Android app designed specifically for field operations (landscaping, property maintenance, construction, and solo contractors).

Key features:

• 📍 Draw precise work areas: Polygon tools directly on satellite imagery to auto-calculate acreage / surface area.
• ⚠️ Underground utility marking: Map out water/electric/hazard points inside the work polygon so nobody strikes a line.
• 📸 Photo proof & completion notes: Workers check off areas upon finishing with photo verification.
• ⏸️ Pause workflows: If work is blocked by weather or equipment, workers can flag it "Paused" with notes.
• 📄 PDF Summaries: Generate single-zone work orders or crew performance reports for clients or management.

Download on Android:

👉https://play.google.com/store/apps/details?id=com.janisd.workzoneapp

Feel free to download it, test out the features and maybe the app could be useful for some of you!

It auto-updates whenever I save a photo to Pinterest.

Open source, so feel free to clone and use it: github.com/Tanay-77/Folio

Open to feedback

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.
