Building CoinFlow: My First Personal Finance App (Now in Open Testing)
Source: Dev.to
🚀 I Launched My First Android App – CoinFlow (Open Testing Now Live)
After months of late‑night development sessions, debugging, redesigning, and rethinking UX decisions, I finally published my first Android app on Google Play 🎉.

💡 Why I Built It
As someone who likes to track expenses and manage multiple wallets, I noticed most finance apps felt either:
- Too complicated
- Too cluttered
- Heavy and slow
- Uncomfortable from a privacy perspective
I decided to build something that is:
- ✔ Clean
- ✔ Modern
- ✔ Privacy‑first
- ✔ Focused on essential features
- ✔ Smooth and intuitive
🏗 What CoinFlow Does
CoinFlow is a personal finance app that helps you:
- 💰 Manage multiple wallets (with currency support)
- 📊 Track budgets with progress indicators
- 🎯 Set financial goals
- 🔄 Handle recurring transactions
- 📸 Attach receipts to transactions
- 📈 Organize categories, tags, filters
- 📤 Export everything to Excel
- 🔒 Protect data with a locally stored PIN (no server storage)
All financial data stays on the device—no server tracking, no external data processing.
🎨 Design Approach
I focused heavily on UI/UX, incorporating:
- Glass‑morphism inspired UI
- Smooth transitions
- Dark theme optimized for comfort
- Clear financial visual hierarchy
The goal was a premium feel while remaining simple.
🧠 What I Learned
Shipping my first app taught me:
- UX decisions matter more than feature count
- Edge cases are endless
- Performance tuning takes time
- Testing on different devices reveals surprises
- Publishing on Google Play is a journey in itself
Most importantly: Done is better than perfect.
🔬 Open Testing
CoinFlow is currently in Open Testing, meaning anyone can install and test it. I would genuinely appreciate feedback on:
- UX clarity
- Performance
- Missing features
- Confusing flows
- Bugs (especially edge cases)

🌱 What’s Next?
I’m planning to:
- Improve analytics (privacy‑safe)
- Add more financial insights
- Introduce smarter budgeting logic
- Continue polishing UX based on feedback
If you’ve ever published your first app, you know how nerve‑wracking it feels. Any feedback, even critical, is welcome 🙌.
Thanks for reading.
