BillBox: Offline Bill Tracker

BillBox is a simple, private bill management app that runs entirely on your device. No cloud. No servers. No tracking. Just your bills, your data, your control. TRACK YOUR BILLS Add your bills with name, amount, due date, and frequency. BillBox handles the rest — sorting by urgency, flagging overdue bills, and calculating your monthly total. Support for weekly, monthly, quarterly, yearly, one-time, and custom billing cycles. GET REMINDERS Never miss a payment. Set up due-day alerts, advance reminders, and overdue notifications. Choose your preferred times and how many days in advance you want to be reminded. PAYMENT HISTORY Every payment you mark is recorded with date, amount, and method. View your full history, filter by date range or payment method, and export to CSV or PDF. VOICE INPUT Say it, don't type it. Tap the mic and speak your bill details — name, amount, frequency, and due date. BillBox parses it instantly using your phone's built-in speech recognition. BACKUP & RESTORE Your data is automatically backed up every 7 days to your Downloads folder. Create manual backups anytime. Restore with a single tap. All backup files are local JSON — no cloud involved. IMPORT & EXPORT Import bills from CSV files. Export your bills or payment history to CSV and PDF. Fully compatible with Excel and Google Sheets. PIN LOCK Protect your financial info with a 4-digit PIN and security question. Your PIN is hashed with PBKDF2 encryption — never stored in plain text. 27 CURRENCIES Track bills in USD, EUR, GBP, PKR, INR, JPY, and 21 more currencies. Amounts display with the correct symbol and decimal formatting everywhere in the app. DARK MODE Switch between Light, Dark, and System themes. Your eyes will thank you. PRIVACY FIRST BillBox has no backend servers, no analytics, no advertising SDKs, and no account system. Your bill data never leaves your device. The only network activity is Google Play purchase verification and anonymous crash reports to help us fix bugs. FREE & PRO BillBox is free with up to 5 bills and full access to every feature. BillBox Pro is a one-time purchase — no subscription — for unlimited bills. Created by Khalid Qadir and Nouman Khan.
