Split the Bill

Split the Bill

The Challenge

Splitting restaurant bills and group expenses always leads to awkward math and unfair splits. People needed a fast, fair way to divide costs down to the item level.

Our Solution

We built a bill-splitting app with itemized expense assignment, automatic tip and tax calculation, and a history of past splits. The Expo mobile app works offline and syncs when connected. Admin dashboard tracks usage analytics.

Results

  • Itemized bill splitting with per-person assignment
  • Automatic tip and tax calculation
  • Split history with receipt-style summaries
  • Expo mobile app for iOS and Android
