About this app

The Fair Calculator helps you and your friends track shared expenses for travel and daily life, including joint expenses, common costs, personal spending, shared bills, purchases made by friends, shopping lists, payment records, notifications, and data exports. Data is synced to your account and joined groups via Firebase, allowing for easy viewing across multiple devices and collaboration with members. A Pro subscription unlocks advanced reporting, more groups, and receipt scanning features.
All your travel expenses, including splitting costs with friends, sharing bills, making purchases, and settling accounts, can be managed with one app.
