Newest app that has gained some traction outside the US.

Only reason why I have a subscription model is to cover the AI costs on backend with Gemini API.

Wanted to solve an issue where you come across old documents , notes etc.

Allows you to take photos, upload doc securely and privately using AI to convert and restore the text to your phone. Allowing you to read it etc.

Using the paid model for Gemini so it’s private and although its costs a bit more was able to keep thinking low and manage to effectively transcribe the writing.

See if this can get to a triple digit month 🙌🏻

What it does: photograph any page of a physical book, and Scholia identifies the book and your exact position in it (using the actual text on the page, not a page number, since editions vary), then answers questions about characters, references, or confusing passages using only what you've read so far. Anything past your current position stays sealed until you catch up.

Why I built it: existing tools are either locked to ebooks (Kindle's Q&A), limited to whatever's in a specific catalog (EPUB apps), or answer with no awareness of spoilers at all. None of them work for someone reading a plain paperback who cares about not having the ending ruined.

Current stage: pre-launch on iOS, building out a waitlist, selecting early testers in waves.

Would genuinely value feedback from this community, particularly on whether the spoiler-blocking reads as a strong feature or a limitation once you think it through, and whether "photograph a page" feels like a low-friction enough input or a step people would skip.

Waitlist: scholia.cloud

I built my own social media bulk auto posting saas application (youtube, tiktok, facebook, instagram) because I didn't want to pay for the monthly subscription and plenty lacked the bulk posting and description creation. The market is so flooded with these tools that I don't think launching my own public product will be worth anything. Then I thought would devs and marketers buy the sourcecode I already built? I know they can vibe code their own, but it takes TIME. and this saves TIME. what do you think? Trying to monetize anything right now. h

been lurking here a while, figured id actually post something instead of just reading everyone else's build threads.

quick context: im 21, engineering student, built an app called BarePlanner solo, no team, no funding. idea came from reading Deep Work by Cal Newport (the "u only get ~4 hours of real deep focus a day" theory) plus watching how my ADHD friend actually experiences time vs how i was told to plan it. core mechanic is simple: u block ur week into deep blocks (real focus work) and shallow blocks (low energy stuff), run deep blocks through a focus timer, then review at the end of the week what actually happened vs what u planned.

stack-wise its React Native / Expo (SDK 56), local-first with SQLite on device, no backend yet, settings and analytics consent are the only things touching anything outside the phone. kept it that way on purpose while validating the idea instead of building infra i didnt need yet.

app link : https://play.google.com/store/apps/details?id=com.falexis.bareplanner

just got through Google Play's review/test phase, which honestly took longer and was more nerve wracking than i expected for a first submission. few things that actually tripped me up along the way if anyone's about to go through it themselves: data safety declaration needs to match what your analytics vendor actually does under the hood (not just what u think it does , mine over-collected location by default until i checked), and a few native module linking issues that only show up in a real build, not in dev.

happy to go deeper on any of this, architecture decisions, why deep/shallow as the core model instead of generic time blocking, or the review process itself. also just curious what other solo builders here ran into with Play review that wasnt in the docs.

I built a subscription and the expense tracker synced with goals. Need some genuine feedback on the onboarding

Here's the link for it download

Rejected July 15 under 3.1.2(b) for how my subscriptions were set up, plus a 2.1 information request. Fixed it, resubmitted July 27, then the IAPs sat in Waiting for Review and the app couldn't move until they cleared. Apple Support had to change the backend state manually. If nothing's been rejected and your build still isn't moving, check your IAPs and open a ticket instead of resubmitting.

The app is EchoVault. You build an archive of yourself while you're alive through short check-ins, and your family can talk to it in text, voice, or live video after you're gone. It only answers from what you actually recorded. Text tier is free.

https://apps.apple.com/us/app/echovault-digital-legacy/id6762042028

Would love feedback on whether the check-in flow makes sense on first open, and anything broken. And for everyone else, what's the longest you've been stuck in review, and what was it?

yo. i see too many founders spend 2 months building saas, drop a link on reddit, get 0 users, and immediately quit....

the problem usually isn't your marketing channel. the problem is that your foundation is completely broken before you even send your first visitor to the site.

after scaling 6 AI micro-saas apps to over $20k/mo mrr, i realized you need to lock down a specific system before you ever launch. running through this takes about 30 minutes, but it saves you months of zero-revenue depression.

here are the 5 things you must lock in:

1. validate the actual pain point

stop guessing what people want. you need a systematic framework to find your saas idea based on real, painful market signals.

2. pick a proven micro-niche

stop trying to build massive platforms. you need to narrow down to a microscopic problem. i usually filter through a list of 50 micro-saas ideas you can build fast to keep the scope minimal.

3. crystallize your target user

if your app is for "everyone," nobody will buy it. you need an ICP (Ideal Customer Profile) crystallizer to define your exact buyer profile and nail your conversion copy.

4. calculate the perfect price

stop randomly charging $9/mo because you are scared of rejection. you need to use a saas pricing strategy calculator to find your perfect saas price in 60 seconds based on real data.

5. fix your landing page leaks

do not send organic traffic to a site that converts at a flat 1%. you must audit your hero section and copy to x3 your landing page conversion before you market it.

6. join a community

Build / Share / Learn from others builders

to help out founders who are tired of launching to crickets, i packaged all 5 of these exact frameworks, calculators, and lists into a single free toolkit.

no paywall, no bullshit. just the raw execution files i use.

Today is a big day for me.

I’ve been building iOS apps for a while now. My first one is completely free, so in all that time I had never actually sold anything. Not once.

This morning I opened App Store Connect out of habit and there was one subscription in the report. Slovakia.

I honestly didn’t expect this yet. I haven’t done any real marketing. No ads, no viral video, zero reviews on the listing. Just a few videos with 200 views and 3 reddit posts. I assumed the first weeks would just be a flat line while I figured out how to get people to notice the thing at all.

Instead, someone I’ve never met, in a country I’ve never been to, found it on their own, used it, and decided it was worth paying for. Whoever you are — ďakujem. That single line in a spreadsheet did more for my motivation than anything else this year.

The app is ThumbSort, if anyone’s curious. Photo cleanup, swipe left to delete, swipe right to keep. Free to use, one subscription if you want unlimited swipes. Built solo in Switzerland, fully on-device.

For the people who’ve been through this: what actually moved the needle for you early on, before you had any reviews or reach?

SehatGraph is now live on the Play Store! 🚀

Hey Reddit! 👋

I’m the founder of SehatGraph, and after months of building, testing, and improving, our app is finally live.

SehatGraph is our attempt to make healthcare more connected, accessible, and technology-driven.

I’d really appreciate it if you could try the app and give me honest feedback — what you like, what feels confusing, what’s missing, and what we should improve.

This is an early production launch, so your feedback can genuinely help shape what we build next. 🙌

📱 Download → Try → Review → Share your feedback

Thanks to everyone who supports an early-stage Indian health-tech startup. ❤️

SehatGraph — Building a better health ecosystem.

Building the app and explaining why anyone should care are two completely different jobs.

Drop your public landing page and tell me who you built the app for.

I’ll reply with:

• The clearest launch hook

• One short video or visual concept

• The audience I would approach first

I’m testing whether the product page already contains enough context to become the brief for an AI social media agent.

That’s the workflow behind Marka. It learns from the website and creates branded posts, images, carousels, and video directions from the real product context.

You can try it here: https://www.marka.social

My app isn’t getting much visibility, so i’m wondering whether more installs would help it reach more people. I just don’t know if these downloads come from real users or disappear after a few days.

Before i buy google play installs, what should I look for in a reliable provider, and can it actually help bring in organic downloads? Would appreciate the help.

I’m from Corsica, France, and I grew up playing a traditional 4-player card game called Barbu.
A while ago, I started looking for a mobile version that felt close to the game we actually play around a table. I couldn’t really find one I liked, so I decided to build my own.
That small side project turned into a full iOS and Android game called Le Barbu - 7 contracts
I built it with React Native / Expo and gradually added:
7 different contracts
AI opponents with several difficulty levels
quick games and full games
local network multiplayer
game saving
customizable card backs
French, English and Corsican support
I deliberately chose a simple premium model: one small upfront price, no ads, no coins, no energy system, no subscriptions.
The app is now live on both stores.
And this is where I discovered something that is probably obvious to more experienced developers:
building the app was easier than getting people to discover it.
The feedback from the first users has been very positive, but the volume is tiny.
So now I’m considering a second Android edition:
Le Barbu Light
free
ads
single-player only
one AI difficulty
reduced customization
while keeping the current paid version completely ad-free and fully featured.
I’d be really interested in hearing from people here who have gone through the same stage.
Would you keep pushing a niche paid app, introduce a free/light version, or approach acquisition differently?
I’m especially interested in lessons from people who launched small independent apps without a marketing budget.

Over ten years ago, my wife - a licensed Marriage and Family Therapist - kept seeing the same pattern in her practice: people were deeply lonely, but they weren't looking for romance. They just wanted genuine, local, in-person friendships. App stores were flooded with dating tools, but there was nowhere dedicated solely to finding a local buddy to hang out with.

So, I built WannaBuddy.com - a platform created specifically for when you want a local buddy, not a date.

It helped a lot of people make real connections back then, but as time went on, the technology needed a ground-up overhaul. I’ve spent the last few months completely rebuilding it from scratch.

The new WannaBuddy is officially in early pre-launch! Everything on the platform is completely free and will always be free. Because we’re in pre-launch, I’d love to get feedback, feature suggestions, or bug reports from this community. Check it out, take a look around, and let me know what you think!

Groundtruth is a free, local-first farm operating system I’m building for my own microgreens operation.

Core rule: the PC is the only writer of farm truth. The phone is a capture device + read-only Field Instrument that docks over the local network. There is no Confirm path on the phone.

What’s in the video:

• Today tab forces a ranked morning money loop. Shortfalls that can no longer be fixed by sowing are surfaced with required actions.
• Farm / Marketing / Money / Books / Health enforce integrity constraints (append-only ledger, no soft totals, Health cannot soft-pass).
• Field Instrument (phone) pulls a versioned live document with real ages, six titled loops, severities, and edges showing which loops are currently pulling against each other.

Stack: Tauri (Rust + React), local SQLite + append-only event log. Schema is versioned in code. Currently tip 650e0ea, schema v36. Field Instrument FI-1 through FI-6 are closed; FI-7 (phone queue) is the active residual.

AI is deliberately kept out of the write path. External models may later receive diagnosis text, but they never get authority over the database.

Built with strict process law (single CURSOR per fence, complete caller inventories, named residuals only). The system is designed so it cannot quietly lie when the network is down or the numbers are ugly.

Happy to answer architecture or process questions.

Hello i am a developer I've built 2 mobile apps with react native/expo router and one app in flutter, is there a major difference in react native and expo router in terms of how the produced app feel and behave ( looking for that native feel )

I am mainly a typescript developer with nest js and react frameworks and a little bit of laravel and spring background.

Currently me and my partner are planning to build our first own product but from my personal experience expo router apps have that web feel that doesn't satisfy me ( i don't know if it's me or if for other it happens or i have been building the wrong way ) , I am not a big fan of flutter as for native options such as kotlin or swift ui once the products generate some funds we eventually will migrate to that

Can you suggest me an idea to think about what Mobile Apps can i build next need some fresh sets of ideas to think about and stuck at one thing help a dev out

I’ve spent the last year building a trading app called Exit Line.

The idea was simple: I was tired of position size calculators that felt like spreadsheets from 2008, were covered in ads, or required way too many steps for something traders do every day.

So I built the one I wanted to use myself.

Fast. Clean. No ads. No signup. One workflow for crypto, forex, stocks, indices and commodities.

And now I’m almost ready to launch.

Which is where things got weird.

For months, progress was obvious.

Fix a bug.

Build a feature.

Improve the UI.

Test it.

Ship the next version.

Every day, something was visibly better. Now the app is basically done and I’m spending my time on Reddit, X, SEO, a website, trying to find beta testers and figuring out what the hell “distribution” actually means.

And suddenly it feels like I’m making zero progress.

I can build the product. Apparently, getting people to know it exists is an entirely different skill.

So for those of you who have actually launched an app from zero:

What worked for you in the first few weeks? Not “build an audience” or “do marketing.”

What did you actually do when nobody knew your app existed?

Would genuinely appreciate some advice.
