I got tired of not knowing where my money went, so I built my own expense tracker. It's free, no ads, no subscription.
I'm not a finance person. I'm just someone who kept hitting end of month and wondering where it all went.
The stack
React Native + Expo, SQLite on-device, Zustand for state, Reanimated for animations. Fully local with optional cloud sync.
Every app I tried either wanted $10/month, shoved ads in my face, or was so bloated I stopped using it after a week. So I built my own.
It tracks:
- Monthly expenses by category
- Recurring subscriptions (so you actually see how much Netflix + Spotify + everything else adds up per month)
- A personal ledger for money you've sent or received from people
- Multi-currency support if you deal with more than one
- Budget limits with warnings when you're close
Your data stays on your device, with optional cloud sync.
(It’s an offline-first app, so everything works without internet.)
Download the app here .
It's completely free. I built this for myself and figured other people might find it useful too.
Happy to answer questions or take feedback — still actively working on it.
