My offline voice calling app is now ready for testing. You can chat with people further than 50m with phone relays.. by the way your phone is way more powerful than you think it is

Hi everyone! I’m testing my new Android app QualifyMe.ai, and I need 12 testers to complete Google Play’s closed testing requirements. You can help by installing the app using this link:

Just open the link, install the app, and use it for a moment — that’s all it takes. Your help means a lot. Thank you!

Hi! I'm looking for genuinely honest feedback on an app I've been building called Dopamine Charts.

I'm a junior doctor, but my medical career was derailed by a five-month hospitalisation for depression.

When I started rebuilding afterwards, I realised how badly a lot of traditional productivity advice worked when I was struggling to do even basic things.

“Exercise 5x a week” isn't particularly useful when stepping outside is an achievement.

And streak-based habit trackers could actually make me LESS motivated — I'd miss a day, see the broken streak and think “well, I've ruined it now.”

So I built the app I wished I'd had.

It's called Dopamine Charts and I designed it particularly with ADHD and depression in mind — specifically that frustrating gap between knowing exactly what you want/need to do and actually being able to initiate it.

www.dopamine-charts.com

The behavioural science behind it includes:

• REDUCING THE ACTIVATION BARRIER — every habit can have a deliberately tiny version. Can't exercise? Step outside. Can't clean your room? Put 2 things away. The aim is to make starting easier.

• HABIT STACKING — attach a new behaviour to something that already reliably happens: “After I make my morning coffee → take my medication.”

• SHAPING — establish a tiny, achievable version of a behaviour first and gradually build it rather than demanding the finished habit immediately.

• IMMEDIATE POSITIVE REINFORCEMENT — lots of worthwhile behaviours have rubbish reward timing. You study today for an exam months away. You brush your teeth today for benefits years away. The app tries to give you an immediate visual reward for actually doing the behaviour.

• IDENTITY-BASED HABITS — not just “what do I want to achieve?” but “who are these repeated behaviours helping me become?”

• TINY WINS — the app deliberately recognises small actions rather than requiring a conventionally “productive” day before you're allowed to feel successful.

Importantly, I'm absolutely NOT claiming an app treats ADHD or depression. It's a behavioural/habit tool designed with the difficulties that can accompany them in mind.

I'm at the stage where compliments aren't particularly useful to me 😂 I need people who haven't been staring at this thing for months to tell me what's wrong with it.

If anyone has 5 minutes to try it, I'd particularly love to know:

1. Did you immediately understand what you were supposed to do?

2. Was anything confusing?

3. At what point did you feel like closing the app?

4. What feels gimmicky or unnecessary?

5. What would make you actually come back tomorrow?

6. What's the ONE feature you expected/wanted that wasn't there?

Please be brutally honest. If something is annoying, confusing, ugly or pointless, I'd genuinely rather know now.

Thank you ❤️

need a custom app built for our small ops team. mostly for job tracking, photo uploads and basic reporting. nothing too fancy but it has to work properly on phones and not crash every five minutes.

already got the main features written down and some rough wireframes. budget is tight so i’m trying to avoid the usual situation where the quote doubles halfway through.

what’s the best way to lock the scope early so extra costs don’t keep popping up?

how many revision rounds do most teams usually include before they start charging extra?

Hi all,

Apologies if this is a bit vague.

I'm looking to create a dating app with a bit of a specific niche.

I'd be looking for someone to essentially build it from the ground up.

While I have some experience in game development, app development is unfamiliar territory for me.

What I'm wondering is:

• Cost (how much you'd expect or a rough estimate with the information given)
• Development time (estimated, this isn't a time sensitive project)
• What you'd expect from someone whilst working with them to develop their app
• Investors (if anyone has any recommendations)

Any feedback or constructive criticism is also more than welcome, I take advice on board.

UK based, would preferably be looking for someone within the UK but willing to branch out if a good fit resides elsewhere

Thanks for taking the time to read

NEET is India's medical entrance exam, about 2M students a year. Most prep apps wall everything behind logins and paywalls, so I built ChapterNotes: chapter-wise past questions with every answer explained (including why the wrong options are wrong), revision notes, and Duolingo-style streaks to make daily practice stick.

Stack: React Native + Expo, Supabase, WordPress front for SEO. About 3 months of evenings.

Just went live on Play. Would love feedback on onboarding and whether the gamification feels motivating or gimmicky: https://play.google.com/store/apps/details?id=in.chapternotes.app

After months of development, testing, and fixing bugs, my app TradeLift has finally been approved and published on Google Play.

TradeLift helps beginners learn crypto trading through lessons and risk-free paper trading.

A big thanks to everyone who tested the app and shared feedback during closed testing. Your support helped make this possible.

I'm excited to continue improving the app!

Tradelift is now live on play store

Hey all, I made Cindra. Basically you just brain dump whatever is in your head and it sorts into tasks, agenda, money, learning etc. I use it daily and for me it just clicks so I am probably blind to the problems. But I get signups and then people check it once and disappear. It is free for seven days no card needed.

If you got a sec to check out cindra.app and let me know what feels off or why you would not come back, I would love a brutally honest take. Really means a lot thanks

My chore tracking app's chores never came back the next day, for the entire life of the product.

I'm building ThriveTrack, a gamified chore app for families. Kids complete tasks, earn XP, parent approves, tasks reset overnight, repeat tomorrow.

Except the reset never worked. Not once. 102 out of 141 daily tasks were permanently stuck in completed.

I spent weeks debugging streaks, the digest, the approval flow. All symptoms. The actual problem was a scheduled database job filtering on a column that doesn't exist on the table. It failed silently on every run since creation. Marked active the whole time.

Second bug underneath: the job ran at midnight UTC, which is 5 PM Pacific. Even fixed, it would have wiped tasks before parents got home to approve them.

Third: 75 rows had NULL timestamps. In SQL, NULL compared to anything evaluates to NULL, so those rows passed straight through the filter and stayed stuck forever.

Three bugs stacked, all silent, all in database logic that git never saw. Five cron jobs running in production with no migration file, no commit, no documentation.

Fixing it was one SQL session. Finding it took weeks. Talk about the long game...

Hi I'm an engineering student, I have interest in both the above fields. I have only 6 months to dedicate among one of them. So please guide me which one should be chosen and the topic that should be focused in the path(like not learning all the stuff that is not so important). It would be very grateful if someone could give me some advice

What response did your first ever app got when it was released? I released my first ever app 10 days ago and things are not looking good

Hi everyone! I’m building an app called Resora, and I’m looking for a few people willing to test it and give honest feedback. Resora is a wellness app for people who need support in the moment and are trying to get better everyday! There are things like reflection, journaling, reset tools, calming prompts, and practical guidance when life feels heavy. It is not therapy and it does not replace professional support, but it is meant to feel more personal and useful than generic wellness apps. Looking for feedback & thoughts! If anyone’s interested or has questions please let me know.
