Casha
A personal finance tracker that doesn't get in your way.
---
Most finance apps make you feel like you're filing taxes. Casha doesn't.
It's built around one idea: tracking your money should take seconds, not minutes. Clean interface, zero clutter, everything exactly where you'd expect it.
---
## What it does
Casha gives you a real-time picture of your finances without overwhelming you with features you'll never use. Add a transaction in two taps, see your balance update instantly, know exactly how far into your monthly budget you are — all from a single screen.
It's not trying to be a spreadsheet. It's trying to be the app you actually open.

## ✦ Features
**Balance Card**
The centerpiece of the dashboard. Your total balance, rendered on a customizable gradient card with a gyroscope-powered 3D tilt effect. Long-press to edit the gradient colors and type — linear, radial, sweep, or solid.
**Income & Expense Tracking**
Every transaction gets a category, an icon, an optional note, and a date. The list is instantly searchable and filterable by type. Nothing is buried.
**Category Breakdown**
A dedicated screen with pie and bar charts showing exactly where your money comes from and where it goes. Switch between expenses and income with a single tap.
**Monthly Budget**
Set a spending limit and watch a progress bar fill up in real time. Goes red when you're over — politely, not aggressively.
**Multi-currency Support**
USD, EUR, BYN, RUB — pick your primary currency in settings. Exchange rates are fetched automatically.
**Biometric Lock**
Optional fingerprint protection on launch. One toggle in settings, zero friction in daily use.
**Dark & Light Theme**
Follows your system theme automatically. Both themes are fully designed — not just inverted colors.
**Localization**
English and Russian, switchable in settings. Date formats, month names, category labels — everything adapts.
**Amount Formatting**
Choose between compact (1.2K) or full number display depending on how you think about money.
