BillSplitAudit: Roommate Payment Tracker
Automatically categorizes shared expenses and calculates who owes whom, handling complex multi-person splits with receipt photo uploads for roommates and group living situations.
The Problem
Roommates constantly argue about shared bills (rent splits, utilities, groceries, household items) because tracking who paid what and who owes whom is manual, error-prone, and creates friction. Existing apps like Splitwise require manual entry and don't handle the complexity of partial payments, recurring bills with different split percentages, or landlord-deposited rent that needs attribution.
Target Audience
College students and young professionals (ages 20-35) living in shared housing, particularly in expensive metros where bill-splitting disputes are frequent and create lasting tension.
Why Now?
Post-pandemic, co-living and house-sharing is growing as housing costs spike; Gen Z expects frictionless digital tools for money management and is willing to adopt niche apps.
What's Missing
Existing solutions treat roommate splits like general group expenses (designed for trip splitting) rather than recurring, proportional household bills. No solution handles photo-based expense capture with automatic OCR and smart categorization.
