About

TapSplit

Splitting a bill shouldn't feel like homework. TapSplit reads the receipt with AI — snap a photo or import a PDF invoice — and lets each person tap the items they had. Tax, tip, and service charges get shared proportionally to what everyone actually ordered — no rounding, no guessing, no one paying for the drinks they didn't drink. WHY TAPSPLIT • SCAN A PHOTO OR IMPORT A PDF — Aim at a paper receipt or drop in a PDF invoice from Uber Eats, Glovo, or your favourite delivery app. TapSplit reads every line item in seconds. Handwritten totals, faded thermal paper, multi-column bills — TapSplit handles all of them. • NO INSTALL FOR YOUR FRIENDS — Share a link. Guests pick their items in the browser and see exactly what they owe. Nobody needs an account. • FAIR SPLITS, AUTOMATICALLY — Tax and service charges are split by consumption, not evenly. If you had a €5 salad and your friend had the €40 steak, you don't pay half the tax. • GROUPS THAT LAST — Weekend trip? Shared apartment? Set up a group once and every future expense feeds into the same balance sheet. • PAY YOUR WAY — MB WAY, Revolut, PayPal, PIX — set your preferred method once, everyone knows exactly how to send you back. • ONE-TAP QUICK SPLIT — At the table, tap "Quick split" on the home screen, scan, done. No group creation form to fill in first. BUILT FOR THE REAL WORLD TapSplit works whether you're a couple splitting rent, five friends on a ski trip, or ten coworkers at a birthday dinner. Multi-currency for travel. Offline-safe when reception is bad. Export to CSV when tax season comes. PRIVACY-FIRST Your receipts and expense data are yours. We never sell your information, and we never advertise on top of your data. Download TapSplit and never do restaurant math again.
