Show HN: Minimal Portfolio Tracker for Stocks, Crypto, Gold and Funds

https://play.google.com/store/apps/details?id=com.ahmetyildiz.portfoyapp&hl=en_US
1•ahmtyldz•1h ago
I built a simple portfolio tracking app to view daily and total profit/loss clearly.

I invest across Turkish stocks, US stocks, crypto, gold and mutual funds. Most existing apps felt either too complicated or didn't show daily performance in a clean way. So I created my own.

Key features: - Track stocks, crypto, commodities, FX, and funds in one place - Daily and total P/L, with quick category-level summaries - Clean UI focused on “check your positions in 5 seconds” - Optional account sync (Firebase) or full offline use - Data caching to reduce API calls

Tech stack: - Flutter (mobile) - Node.js + Express backend - Firebase Authentication + Firestore (optional sync) - Local caching layer for API efficiency

Screenshots: (link) App Store / Play Store: (link) GitHub (optional): (link)

I’d really appreciate feedback on: - UI clarity and layout - Which metrics matter most in daily use - Whether a “premium” tier for advanced analytics makes sense

Thanks for taking a look!
