About this app

Billiii helps you stay on top of every bill, subscription, and recurring payment — so you never miss a due date again.

WHY BILLIII?
The average household juggles 12+ recurring payments. Missed bills mean late fees, damaged credit, and stress. Billiii puts you back in control.

SIMPLE BILL TRACKING
Add your bills in seconds. Set the name, amount, billing cycle, and due date. Billiii calculates your monthly and yearly spending automatically.

SMART REMINDERS
Get notified before bills are due. Choose when to be reminded: on the day, 1 day before, 3 days, 1 week, 2 weeks, or 1 month before.

SPENDING OVERVIEW
See your total monthly and yearly costs at a glance. Bills are colour-coded by status — green for upcoming, amber for due soon, red for overdue.

SEARCH & FILTER
Quickly find any bill. Filter by All, Overdue, Due Soon, or Later to focus on what matters right now.

YOUR DATA STAYS PRIVATE
All your data is stored locally on your device. No accounts, no cloud, no bank linking. Your information never leaves your phone.

MULTI-CURRENCY SUPPORT
Track bills in GBP, USD, EUR, and 20+ other currencies. Perfect for managing payments across different countries.

CATEGORIES & ORGANISATION
Organise bills by type: Rent/Mortgage, Utilities, Insurance, Phone, Internet, Subscriptions, Transport, and more. Pro users can create custom categories.

DARK & AMOLED THEMES
