Vouch
The anti-Splitwise
Roommate and trip splits that cite the paper. Snap a receipt, housemates tap what they owe, everyone vouches — nobody argues about organic blueberries.
Problem
Splitwise makes housemates retype every line from a crumpled receipt. Even splits feel unfair, Venmo threads turn into fights, and nobody trusts the total because the paper never made it into the app.
Approach
Vouch keeps the receipt as proof. Upload a photo (or type the lines); Interfaze pulls merchant, date, total, and priced items. Housemates open a share link and tap I owe this or Not mine. Groups track who owes whom after people have vouched.
