I'm Jerry, founder of Monni.

I'm giving 20 people a free 1-year membership in exchange for blunt feedback on the first week.

Monni is an iOS money brief for people who want a lighter weekly check-in instead of a full budgeting system.

Best fit:

• you use or used Mint, Monarch, YNAB, Simplifi, spreadsheets, or mental math
• you want a clearer "what's safe to spend this week?" view
• you're okay telling me what feels confusing or untrustworthy

App Store: https://apps.apple.com/us/app/monni-ai-money-tracker/id6778174904

Website: https://monni.io

DM me if you want one. I'll reply asking for the email to grant access to, then manually add the free year.

Please don't post your email publicly, and don't send balances, screenshots, account numbers, addresses, passwords, or private financial details. High-level workflow feedback is enough.

I may be biased because I'm the founder of Monni.io.

I'm a solo Android dev. This started as a personal itch: I wanted to know exactly how many lectures I could skip before my attendance dropped below the 75% my college enforces. Every existing app either made me type in semester totals, buried me in banner ads, or wanted a login for a thing that runs perfectly fine offline.

So I built Bunku. The whole idea is one number: how many classes can I safely bunk in this subject right now, and if I've already fallen behind, how many do I need to attend to climb back above my target. You add subjects, set a minimum % per subject (75, 80, whatever your college wants), and tap Present or Absent after each class. It does the maths — live percentage, safe-to-bunk count, colour-coded Safe / Warning / At Risk.

A few decisions I made on purpose:

• No ads, ever — free tier or paid. This was the whole reason I started, so putting ads in would've been hypocritical.
• Fully offline, no account. Your logs never leave the phone. No cloud, no sign-up.
• Pay once, not a subscription. Pro is a one-time unlock (unlimited subjects, backup/restore to a file, CSV export, timetable, reminders). I hate renting software, so I won't make students rent this.
• Free tier is genuinely usable — 3 subjects, no time limit, not a trial that expires.

Slightly weird feature I'm oddly proud of: there are small pass-and-play games built in (2048, Tic-Tac-Toe, Air Hockey) for the gap between lectures. It fits the "college downtime" vibe and it was fun to build.

Tech stack: native Android (Kotlin), local storage only, no backend at all — which is why there's nothing to log into and no server bill to pay.

What I'd love feedback on:

• Is "how many can I bunk" clear enough as the core value, or does the games thing muddy it?
• The biggest competitor auto-imports attendance by reading a screenshot of your college portal (OCR). I'm debating whether that's worth building vs. keeping it dead simple. Curious what makers here would priorities.

— happy to answer anything about the build.

I’m the founder of Ambar, a free iPhone app for people who want social photography without turning every photograph into a video.

The current version includes:

• high-resolution photo posts;
• one photograph at a time in chronological order;
• automatic fullscreen when the phone is turned sideways for landscape images;
• no video, Reels, or audio;
• no public follower counts;
• likes visible only to the person who posted;
• private conversations instead of public comment threads.

The honest limitation is that it is a new social network, so the community is still small. The experience becomes much better if you join with a few friends or photographers you already know.

If you try it, I’d rather hear one thing that feels confusing or unnecessary than receive a generic compliment. What would stop you from using it a second time?

Sensium is a practice app for getting sharper when two wines feel similar, and a fast grape reference when something unfamiliar shows up at dinner.

I built it because I still freeze with the label hidden — even after years of caring too much about wine. Peak low: dinner in Malta, Girgentina and Ġellewża, half the meal on my phone instead of talking to people.

Two modes on purpose:

• Table — open a grape: how it usually tastes/smells + the one tell that sets it apart

• Practice — look-alike pair drills, side-by-side Compare, Blind coaching on aromas / regions / winemaking terms / your own mistakes

Solo maker.

Roast the first minute: what confuses you, and does the table-vs-practice split make sense or feel like a mess?

Disclosure: I'm the developer — posting per the sub's developer guidelines.

I made TapeBoy, an iPhone app that gives your Apple Music now-playing a cassette-deck look: a home-screen widget where the current track rides on a spinning tape, reels turning as it plays. It works with Apple Music — I grew up when getting music took real effort, and I wanted my library to feel like that again.

It's free on the App Store; the cassette widget is a one-time paid unlock (no subscription). If you'd rather try the widget before paying, there's a TestFlight where in-app purchases run in sandbox and never charge you.

Not here to hard-sell, genuinely after feedback what you miss functionally and visually and how does the app work for you.

My story: I'm a high school music teacher. For years I watched students (and honestly myself) fail at daily practice for the same dumb reason: the phone always wins. So as a solo iOS dev I built TuneLock to fix my own problem first.

It uses iOS Screen Time to lock your chosen distracting apps until you've done your daily practice session. Do the practice, everything unlocks, your streak ticks over. There's an emergency release if you genuinely need your apps, and it won't cost you your streak.

To be upfront about pricing (I know the rule): the core loop, practising to unlock your apps plus streak tracking, is free forever, no trial that expires. There's an optional one-time unlock (no subscription) that adds rest days, stats, custom unlock windows and a second ritual. You never have to pay to use the main thing.

Roast away. I especially want it on:

- The Screen Time permission onboarding, which is the scariest moment in the funnel.

- Whether the core idea actually makes you want to practise or just feels like nagging.

- The App Store page: does it sell the value in the first few seconds?
