From zero code to App Store: How I built a productivity app in 6 months using only AI

6 months ago I was a content team lead with an idea for an app. One problem: I had never written a line of code in my life.

Today, SelfOS is live on App Store and Google Play. Here's how it happened.

Why I started
I've always dreamed of creating my own life management app. Smartphones have become such a big part of our lives — I wanted to offload some of the mental organization onto them. Stop keeping everything in my head. Let the phone handle the tasks, goals, habits, shopping lists.

But every app I tried felt either overloaded with features I didn't need, or just... ugly. No aesthetic. No way to make it feel like mine.

So instead of waiting for someone to build what I wanted, I decided to learn and build it myself.

And honestly? I still have so many ideas for where to take this. This is just the beginning.

The tools that made it possible

1. Claude Code in VS Code terminal — this was the game-changer. Claude sees your entire project folder, understands how components connect, and can refactor across files. It felt like pair programming, not just Q&A.

2. Figma AI — helped me design the visual part of the app. I'm not a designer, but with AI suggestions I could create a clean, aesthetic interface that actually looks professional.

3. React + TypeScript — I didn't "learn" them traditionally. I described what I wanted, Claude wrote the code, I learned by reading and tweaking.

4. Capacitor — turned my web app into native iOS/Android apps.

5.RevenueCat — handled subscriptions so I didn't have to figure out App Store payments.

What I built
SelfOS — a personal life management system:

📋 Daily tasks with timeline view
🎯 Goals with steps and progress tracking
✨ Habit tracker
🛒 Shopping lists with categories

Everything stored locally. No accounts, no tracking, no ads in free version. Privacy-first.

3 weeks in the stores — real numbers

📱 ~120 installs (iOS + Android)
💰 6 paying subscribers ($18 MRR)
⭐ 5.0 rating on Google Play
🔍 33% of installs from organic App Store search

Small numbers, but one moment made it real: a stranger from another country bought a yearly subscription. Not a friend. Not family. Someone who found the app and decided it was worth paying for.

What surprised me

Building was the easy part. With AI tools, I could ship features in hours. The code isn't perfect, but it works.
Marketing is 10x harder. I've tried Telegram ads, Apple Search Ads, posting in communities. Most things don't work. Finding what does is the real challenge.
"No-code" is a spectrum. I didn't write code manually, but I had to understand it. Reading error messages, debugging, knowing what's possible — you can't skip that.

What I'd do differently

Start marketing before the app was "ready"
Build an audience while building the product
Launch smaller, iterate faster

What's next

Preparing for Product Hunt launch
Testing TikTok/Reels content
Trying to crack the distribution puzzle

If you're thinking about building something but feel like you "can't code" — you can. The tools exist now. The barrier isn't technical anymore. It's just deciding to start.
