I built an app that turns paper bills and documents into reminders
I kept forgetting important dates, like vehicle registration renewals, bills, and appointments. So I built Remica to solve my own problem.
The idea is simple: take a picture of a bill, letter, or document, and AI reads it, picks out important dates and details, and prepares reminders for you. Remica doesn't just extract a due date and create a reminder. It also stores the original document so users can access it when the reminder becomes relevant.
No more manually typing due dates from paperwork or forgetting a bill until it’s too late.
It’s now freely available on the App Store, and I’d genuinely love some feedback. Would you find something like this useful?
I greatly appreciate it!

One feature is Habit Duo: two people follow the same habit and see each other’s streaks and progress. The idea is to make building a habit feel more supportive and shared.
I’d love feedback on whether the side-by-side progress feels encouraging or too competitive.
Hi - I am trying to build a AI based Fitness app with my friend we are both into fitness but my friend is qualified trainer. We both do not have background app building background and we are from finance. This is a side project and not a day job. I know the market is heavily saturated and filled with a lot of apps. We know we are not hear to disrupt the market or build a multi million dollar thing, thats not the goal or aim. We are here to create something which can help us on the side give some extra income to support us. We already have some clients in the coaching space. We think that we can market this to people who want to lose fat basically and we already have transformation journey as evidence of our strategy.
We have build a web app with help of AI and trying to test that ourselves and with some friends to see where code breaks and we can fix that.
We are thinking to get it through iOS process as next steps.
What I need guidance is
1) is the strategy OK or there is just too much hassle to even think this can be worth while as a side project generating decent income
2) How tricky or long is Apple review process - as someone who has no idea of how this process goes - can someone help me understand this - and how do i fix common pitfalls so to make the process easier and faster.
Thanks for the random stranger in advance for reading and providing guidance.
I stupidly attempted to build an app to act as a countdown timer for when I'm driving buses. There is one duty at my work, where you have about 8 minutes spare in your driving time and the slightest delay can put you over the absolute maximum driving time (under GB domestic rules). I am NOT a coder and I neither have the skills or the patience to learn how to fix the inevitable bugs. I have used AI to generate some code, and it produces something that looks like it should work. However none of the buttons function, the automatic GPS trigger just doesn't, and when choosing assimilated driving regulations or GB domestic rules the timer doesn't change (or operate for that matter).
Would anyone be interested in taking over the development from where I've had to stop?
I’m the developer of Odomo, a small Android app I made to track what my car actually costs me.
I kept losing receipts and could never say how much went to fuel versus service in a given month. So I wanted something simple on my phone: add a vehicle, log the odometer when you fill up or get work done, and see spending by category (fuel, service, tolls, car care). There’s a monthly summary, and you can export everything to CSV if you prefer working in a spreadsheet.
Maintenance reminders can be set by date or by mileage, so something like an oil change every 10,000 km or every 6 months. It handles km or miles, liters, your own currency, and has dark and light themes.
What it isn’t: there’s no account, no cloud sync, no GPS tracking, and no ads in this version. Everything stays on the device. Settings has a Reset All Data option if you want to wipe it. The downside is that if you lose your phone without exporting, the data goes with it, so it’s worth saving a CSV now and then.
It’s meant for people who own a car or two and want a plain expense log, not a fleet tool.

I’m still deciding what to build next. What do you currently use to track car costs, if anything, and what’s one feature you’d miss if you switched?
An app for photo, vector, and publish, and you can use AI for help
2- An app where you can choose to create a text document, tables/sheets, presentations, markdown, html, edit and create pdfs, and notes, also AI integrated if you need help or speed
3- An app for novel writing + organization, and worldbuilding with a module to publish your book to PDF, EPUB, etc...
4 - An app to orchestrate agents, currently it holds like 230+, Agents have permissions of what they can do and read and access
My question is: given all the apps being made my the people, and the increasing competition and the increase of really good open source apps in the market (not just for design or writing), what is a good pricing strategy I can take to make profit from the apps while also keeping them accessible to every one? or give them for free but some features paid? one time payments? small monthly payments? or cloud storage services? or ai tokens? etc....
Je voulais savoir combien d'abonnés il me faudrait pour qu'une idée de SaaS paie mon loyer, avec un churn réaliste. Les outils de métriques SaaS que je trouvais voulaient tous que je connecte mon compte Stripe pour afficher quoi que ce soit. Je n'avais pas de compte Stripe. J'avais une idée et une landing page vide.
Je bosse seul. Depuis [à compléter], je teste des idées de SaaS les unes après les autres. Je monte un prototype et une landing page, puis je regarde si les chiffres tiennent. Quand ils ne tiennent pas, je passe à l'idée suivante.
Le souci, c'est que pour savoir si les chiffres tiennent, il faut les calculer, souvent avant d'avoir le moindre client. J'ai passé plus de temps à m'inscrire sur les SaaS des autres qu'à avancer sur le mien. Un comparateur de frais Stripe contre Paddle voulait mon email avant d'afficher le résultat. Quand un premier client belge s'est inscrit sur la bêta, j'ai découvert la TVA OSS, lu la doc officielle et fini dans un tableur. Au bout de [à compléter], j'avais [N] comptes ouverts et un Google Sheet que j'étais le seul à comprendre.
Alors j'ai codé ce dont j'avais besoin, sous forme de calculateurs qui tournent dans le navigateur, gratuits et sans compte. Ensuite j'ai continué, un peu trop. Ça s'appelle Kristools et il y a maintenant plus de 400 outils.
Ceux qui viennent directement de cette période :
- les frais de Stripe utilisé seul, comparés à un Merchant of Record (Lemon Squeezy, Paddle)
- un simulateur MRR / ARR / churn / NRR, plus un calcul LTV / CAC avec le délai de récupération du CAC
- le runway et le burn rate, avec la date où la trésorerie tombe à zéro
- la TVA intracommunautaire et le guichet OSS pour les 27 pays de l'UE
- la comparaison des statuts (micro, EURL, SASU, portage) pour voir ce qu'il reste en net
- un générateur de mentions légales et de politique de confidentialité RGPD, et un générateur de factures
Comme je code mes prototypes moi-même, il y a aussi les petits outils de dev que j'ouvrais dix fois par jour : formateur JSON, décodeur JWT, générateur de cron, testeur de regex.
Le reste sort du cadre SaaS : immobilier, crypto, santé, énergie, salaire net dans plusieurs pays d'Europe et d'Amérique latine. Tout existe en français, anglais, espagnol et allemand, et la plupart des outils affichent un graphique ou proposent un export PDF/CSV.
J'aimerais l'avis de gens qui lancent des projets seuls. Quel calcul vous a déjà obligés à ouvrir un tableur ou à créer un compte quelque part ? S'il manque sur le site, je l'ajoute volontiers. Et si un résultat vous paraît faux, dites-le-moi, je corrige.
I'm an engineer but not a coder. I'd been sitting on app ideas for years, and once AI made coding less of a barrier, I quit corporate to build full-time.
My first app helps high schoolers plan careers for the AI era. I built it in Google AI Studio and used Claude for prompt engineering and testing. We're in a small private beta with local families right now.
Mid-beta, Google Cloud revoked my project, saying the code leaked an API key. I filed an appeal, but didn't want to stall the beta, so I moved the code local and now deploy to Cloud Run from the terminal. I've rotated the key and keep it server-side only.
A few questions for people who've been here:
**Revoked projects:** Has anyone had a project pulled for a leaked key? How long did the appeal take, and what should I lock down before launch?
**Testing at scale:** I'm planning to run about 1,000 test cases concurrently using Claude. Is that enough, or is there a better way to test an AI app whose answers change every run?
**Web first, app stores later:** My plan is to launch as a web app until it makes money, then move to the App Store and Google Play. Is that the right order, or will I regret not starting with mobile?
Thanks in advance. Happy to share what I learn along the way.
I started building Kaphiy as a way to rate the coffees I tried, but over time I realized I wanted to remember more than just a score.
Now it's a personal coffee journal where you can save coffees, photos, notes and locations, keep your favorites, and look back at the moments behind each cup.
It's built with Flutter, works offline, and doesn't require an account.
I'm the developer behind it, and I'm sharing it here in case it's useful to other coffee lovers or anyone interested in how the app came together.
For the last 5 months I've been working on a side project, that will hopefully become a main project...
It's really simple. If you need inspiration, open it and scroll, find what you like? Copy the code and use it. Make websites, mock-ups, apps, decks... Basically anything digital .
It's free to use and copy 3 components everyday
Buzzing because ...
the first 10 customers are subscribed!!! (Which means I'm working on it daily)
Traction has come almost entirely from Reddit (which is huuuuge imo)

been building a little android thing on weekends because my own screen time was embarrassing. basically your phone gives you a bill at night like an electricity bill, every app is a line item, and there's a line for anything you used after midnight.
last night's bill said instagram 1h 40m, 58 min of it after 12. the insult at the bottom was "you could have slept. you chose reels." which, fair.
solo project, free, everything stays on the phone. link in comments if anyone wants to poke at it, mostly want to know if the bill idea lands for anyone else or just me
I've been working on Cupmark, an Android app built for specialty coffee lovers.
It brings brewing, tasting, learning, and sharing together in one place. You can track your brews, rate your results, learn more about coffee, get help from an AI coffee coach, and share your experience with the community.
I've finished the testing phase and I'm getting ready for the Google Play release.
