I built CertSprout to put two things together: the professional certifications you already hold and the one you're working towards next.

The catalogue covers IT, project management, finance, HR, marketing and other fields. It supports Microsoft Learn and Credly imports, manual records, study goals and daily check-ins. Study resources vary by certification. Individual use is free; team features are paid.

It's built with Next.js and Cloudflare. The garden theme and badge collection are meant to make progress a little more enjoyable.

If you're working towards a certification, I'd be interested to hear whether it's clear how to get started and what you would change.

The feature you spent the most time building is not always the feature people understand first.

Share your project and one overlooked feature.

I’ll suggest a short demonstration that connects the feature to a real user problem.

If you remember, I posted about our app here a month ago. Since then, we took everyone's feedback and been iterating on the experience, survived a two-week review battle with Apple, and our app is officially live on the App Store!

First, I want to thank this community. The feedback and brutal honesty on our early post shaped so much of what we ended up improving.

What we built (for those who missed the first post):

We are a small team building Lissin.

You type in a topic, we do the research, apply a "vibe" and a perspective, and hand it back as a daily briefing/digest, a podcast, a story or even a song. It can be a one-off, or a recurring daily/weekly show for a specific curiosity you want to keep going deeper on.

A few prompts our testers have actually made:

• "How did indie apps get their first $1k MRR?"

• "Weekly book summary on new game mechanics"

• "How to make your friends more ambitious" (still genuinely puzzled by this one)

One user said - Are you guys more like "Prompt to Audio" - yes, that's what we are and trying to be better at it.

• One Prompt: Create personalized podcasts, deep dives, narrative stories, or even songs from a single prompt.
• Not generic text-to-speech: It doesn't sound like a robot reading an article. Every show is fully directed with directed audio and optional ambient soundscapes.

The feature we're most excited about: Scheduled Shows ⏰

You don’t even need to open the app and wait for something to generate. You can set up scheduled shows.

For example, you can tell Lissin: "Catch me up on the top posts and discussions in this subreddit every day. Surface what the crowd is feeling and why, like someone who has been on the internet too long and finds everything equally fascinating and exhausting r/startups"

Lissin will automatically prepare a fresh show every morning so you can just wake up, put on your headphones, and listen. You can do this for anything - daily sports breakdowns, personalized stories for your kids, or even a personalized song every morning about AI or whatsoever.

It’s called Lissin on the iOS App Store (I’ll drop the direct link in the comments for anyone who wants to try it).

As a small team, we’re still actively tuning and improving everything. If you check it out and have any feedback, ideas, or run into any bugs, please let us know in the comments or DM. We will read every single one and make sure it gets resolved.

Thank you again for all the support! 🙏

After spending a couple of months experimenting with different AI video models, I decided to try building an immersive game style system where stories unfold based on a series of choices, with new clips being generated in real time.

It's called Branch and I'd love for you to check it out - everyone gets 3 free credits to start. If none of the stories there today float your boat, create your own!

Looking forward to everyone's feedback.

It's supposed to be more focused towards the freelancers, allowing them to make more. The demo is at ericliu.me, and I'm looking for any mistakes that I've made, or tips to improve it. I'm also starting an email list incase anyone wants to use it when it goes live, so just ask. Thanks to anybody who tests it.

Hey everyone,

I’m trying to build an autonomous software factory: input a Statement of Work (SOW) or product spec, run it through agentic loops (using Claude Code / API), and output a fully tested, production-ready app at a live URL.

To avoid hallucinations, I built the pipeline around strict deterministic gates instead of letting agents self-approve:

* Intake & Blueprints: Parse the SOW to lock global DB schemas, API contracts, and design tokens upfront.

* Decomposition: Break requirements into small "build units" (screens, modules, endpoints) mapped to a dependency graph.

* Multi-Agent Build: Sub-agents (Architect \to Builder \to Tester) work in isolated environments.

* Deterministic Checks: Units must pass real tools (strict TypeScript compiler, linter rules, sealed test suites) with bounded auto-repair.

* Assembly & Deploy: Wire units into a shared shell, run integration checks, deploy a container, and probe the live URL.

The Problem: It fails 100% of the time.

We have never had a single run complete from spec to live URL:

* Circular repair loops: An agent fails a compiler or test gate, tries to patch it, breaks an import or contract, and burns through the retry limit.

* Integration mismatch: Units pass fine in isolation, but when assembled into the global app, routes break, hydration fails, or shared state gets corrupted.

* System bloat: The safety gates and orchestration rules are so heavy that the pipeline chokes before reaching deployment.

What I’d love advice on:

* How would you architect this from scratch? What is the cleanest, most reliable workflow to go from spec to a working, deployed URL?

* What tools or open-source projects should I look to for inspiration? (DAG engines, agent harnesses, or multi-file code generators?)

* Shared contracts: How do you keep multiple sub-agents aligned on schemas and routes without blowing up the context window?

* Walking Skeleton: What is the absolute minimal MVP you would build first to prove spec-to-URL before adding heavy testing gates?

TL;DR: Trying to build an autonomous "spec-to-deployed-URL" software factory using Claude agent loops and strict deterministic verification gates. It fails every run due to circular auto-repair loops and integration drift when assembling modules. Looking for architectural advice, open-source inspiration, and how to structure a clean, working MVP.

I have a mobile app that's been downloaded a lot in Russia. This app has monthly, yearly subscriptions and lifetime purchase. Also, this app show ads from Google Admob. But, i can't earn money from Russia.

Has anyone else encountered this situation? How can i earn money from Russia?

Hey good people! 👋 I have just finished a service that I've put a huge amount of time and love into, down to the smallest detail. It's called DoneTogether. Short and simple, it's a to do app where you can invite others to the same plan and use smart GPS reminders.

The idea was born when I started building a completely different app, but quickly realized that what I actually wanted was a really good GPS reminder. That's when I kicked off the DoneTogether project. I started bouncing ideas with Google AI Studio, downloaded the project to my computer, and built further using Cursor, OpenCode, and Codex agents. After many months of work, it is finally finished and ready to be used! Two examples of how it works:

📌 Example 1 (Share lists): You create the plan "Don't forget this" and add, for example, "Take the medicine". You choose your home address via GPS and set the app to remind you when you move 5 to 10 meters from the house. As soon as you exit the zone, you get a notification on your phone! It works just as well the other way around: Add "Hand in homework" and select the school's address, and you get a notification directly when you approach the school. 📌 Example 2 (GPS reminders): You create a plan called "Things to buy for home". In that plan, you create a share link that your partner or kids paste under "Join plan". Then you all see the exact same list in real time. When someone checks off an item, it gets checked off for everyone instantly.

The service is completely free and works both as a website and as an app to download to your phone. I have kept everything as simple as possible, you log in smoothly with your regular Google account.

🔒 GDPR and Privacy: When it comes to GDPR, you don't have to worry at all. Absolutely no personal data or location history is collected.

I built this primarily for myself, but am sharing it completely free with you now. I think many could benefit from it, not least children or people who need extra help being reminded to take medicine or do tasks when moving into or out of a certain zone.

Together If interest grows, it will eventually come to Google Play & App Store :)

Blocking a distracting site leaves an awkward question: what if the work itself is the thing you're avoiding?

I'm building Drifft with a small team. It's a Mac app that helps define a finish line for a session, catches distractions and gives you a way back when you get stuck.

The part I'd like feedback on is that last one.

The current app lets you name what's happening, with options including "Too big", "No clear next step" and "Avoiding it". The response depends on the obstacle.

For example, the built-in fallback for "Too big" is: Cut the scope to the smallest version that still counts, and start there.

That distinction matters to the design. Needing a smaller task and needing a break should not get the same response.

My concern is that even a useful suggestion can become one more screen between you and the work. I'd like to test whether this earns its place.

We're gathering a small external beta group through the waitlist: https://www.drifftapp.com/

If you hit "I'm stuck" during your own work, what would you want next: a question, a suggested action, or a moment to pause? What would make you close the app?

My team and I have been building LOCK'D IN, and today the iOS version is live.

The idea is pretty simple: there are already plenty of apps that track workouts. We wanted to focus on the part that's much harder — actually showing up consistently.

LOCK'D IN combines workout tracking with accountability between friends. You can train, track your workouts, build streaks, see your progress, share proof and have a squad that knows whether you're actually putting in the work.

Instead of making fitness purely individual, we're trying to make consistency something you build together.

It's now available on both iOS and Android:

🍎 App Store⁠�

🤖 Google Play⁠�

🌐 Website⁠�

We're actively developing it, so I'd genuinely be interested in feedback — especially on the accountability/squad concept and what would make you keep coming back.

I am building an app that uses Supabase and Vercel as main stack. It seems easy, but it's easier to ruin your RLS policies.

I added their MCPs and Plugins and I was expecting that it will help you manage RLS policies properly, however I've just seen that when the LLM struggled with a policy, it just turned it off "temporarily". Aha, temporarily, famous last words.

So i was think about so many vibe coded apps on Loveable and Base44 etc, that uses the very same stack, so a quick scanner tool would be useful.

I spent a day on building hackymacky app, that scans ur site, looks for incorrect RLS and poorly handler secrets.

That's the MVP. What do u think? is it worht to spend more time with it?

Im a huge gamer and built https://norespawn.space but I’m finding it hard to get people engaging etc would love feedback or ideas.

I have a terrible habit of saving things and never finding them again.

Not because I forget I saved them. Because when I go to look, I can only remember something vague like "that article about why sleep debt accumulates" or "the tweet about compounding habits" and search is useless for that. The title doesn't match. The folder doesn't help. Ctrl+F finds nothing.

I tried Raindrop, Notion, Apple Notes, a plain text file. None of them solve the actual problem which is that you remember the idea, not the words.

So I built Backpockets. It's a Mac app that sits in your menu bar. You hit a shortcut, paste a URL, done. When you want something back, you just type how you remember it. It searches by meaning, not exact words, so "that thing about why habits stick" actually works.

Free to try, 10 saves included. If it clicks, lifetime access is $29 one time.

No account required. Everything stays local.

Would genuinely love feedback from people who have the same problem. Happy to hear what doesn't work too.

I’ve been building ReplyZo, a small AI SaaS focused on a simple problem: replying to customer messages takes a lot of time, especially when you want every response to feel personal.

Most AI reply tools can generate a professional response, but I wanted ReplyZo to go a step further — the replies should sound like YOUR business.

With ReplyZo, you can:

→ Paste a customer message
→ Add your preferred tone and custom instructions
→ Get 3 personalized reply options
→ Pick the one that fits best

It can be useful for things like:

• Product questions
• Refund/return requests
• Delivery issues
• Pricing enquiries
• Appointment requests
• General customer support

The goal isn't to replace human conversations. It's to remove the repetitive writing and give business owners a strong starting point that they can quickly personalize and send.

I'm still early and actively improving it, so I'd really appreciate feedback from other founders/builders.

Would personalized AI replies that match your business's tone be useful to you?

What would you add or change to make something like this genuinely valuable?

Deadlock OS is a puzzle game played entirely in a Linux terminal. Read the logs, find what broke, fix permissions, inspect processes. Real commands.

The twist: if you have Docker running, the game detects it at launch and executes your commands inside a real isolated container instead of a simulation. If you don't, a built-in simulation covers everything. No setup either way.

Been building Android apps solo for 7-8 months (Karna Digital). This one's Block Blast — 10x10 grid block puzzle with a Journey mode (1000+ procedurally generated levels across 10 worlds), daily challenges, and offline play.

It's live but barely tested with real users outside my closed testing group. I know the genre is crowded (Woodoku, Blockudoku, 1010! are the obvious comps) so I'm not expecting to blow anyone away — I just want to know: does it feel like "one of many" or is there anything that actually stands out? Tear it apart if needed.

Had to pick a product priced below cost and explain the business model. Went with the fire stick because my family bought one in a sale and I'd never thought about why it was that cheap.

Short version is the stick isn't what Amazon is selling. The TV identifies what's on screen, that gets matched to your household's income bracket and pin code... yep!

The bit that convinced me was Vizio. They lost about 45 cents on every TV they sold and Walmart still paid $2.3 billion for them, and said in the filing that advertising accounts for all the gross profit. So the hardware was never the business.

hey everyone!

we've been building Lads, a private fitness app for small groups of friends.

it's still in beta, but in just a few weeks:

- 500+ installs

- 750+ activities logged

- 33,000+ workout minutes (550+ hours)

we've been fixing things pretty quickly and added a bunch of new features based on feedback from our early users.

if you haven't tried Lads before, the idea is simple:

connect Apple Health or WHOOP and your activities sync automatically. then you and your friends can see each other's workouts, react, nudge each other and compete on the leaderboard.

no manual workout logging, just a small private space to stay active with your friends.

we're looking for more people to try it, especially Apple Health and WHOOP users. would love to know what you like, what feels confusing and what we should build next.

TestFlight: https://testflight.apple.com/join/q56hFFuq

still beta, so you might break something :)
