Sub Zero - Bill Manager

Sub-Zero: Bills & Subscriptions
Are you tired of keeping your bills in a complicated expense manager?

Most expense apps make you log every cent you spend. Sub-Zero is different. It’s a specialized, fully offline Bills, Subscription, and Installment manager that will keep on reminding you of your bills. You'll never miss one of them again.

Stop the "Subscription Creep" and take control of your financial calendar with zero cloud tracking and 100% privacy.

The Proactive Manager You’ve Been Looking For:
Persistent Reminders: Don't just track; get notified. Set multi-day alerts for upcoming bills, expiring free trials, and ending discount periods.

Four Specialized Entry Types: Manage Subscriptions (Netflix, Spotify), Recurring Bills (Electricity, Water), Installment Plans (Gadgets, Appliances), and One-Time Payments in a single, unified list.

Offline-First & Private: No accounts. No cloud. No data collection. Your sensitive financial data lives on your device and nowhere else.

Powerful Tools to Save You Money:
Subscription Graveyard: Built-in "Zombie" detection surfaces apps you pay for but don't use. Log your usage with a single tap and see what’s actually worth your money.

AI-Powered Scanning: Don't type. Use on-device OCR to scan receipts or billing screenshots. We automatically extract the name, amount, and due date for you.

Visual Burn Rate: See your weekly, monthly, and yearly spend at a glance. Our 12-month forecast helps you plan for "peak" billing months before they happen.

Secure & Flexible:
Biometric Lock: Secure your data with fingerprint or face unlock. The app re-locks automatically when in the background.

Variable Bill Support: Not every bill is the same amount. Mark bills as estimates and record the actual payment history to keep your totals accurate.

Multi-Currency Support: Track international services with 48 supported currencies and locally cached exchange rates.

Data Portability: Export your records to CSV for spreadsheets or create a self-contained JSON backup to move your data to a new phone.

Stop scrolling through endless expense categories. Start managing what actually matters. Download Sub-Zero today.
