What is Partly?
Partly is a freemium mobile app designed to remove the friction from sharing expenses with other people — whether it’s a weekend trip, a shared flat, a couple’s budget, or regular nights out with friends. Instead of juggling spreadsheets, notes and long chat threads, you snap a photo of any receipt or bill, let the app’s AI/OCR extract the line items, and then decide exactly how to split the cost: evenly, per item, by percentage or with custom amounts for each person. You can create dedicated spaces for each group or event to keep running totals clear over time and close everything cleanly at the end. Partly focuses on being fast, transparent and fair, so everyone can see what they owe and settle up without awkward conversations or manual math.
What problem it solves
Partly removes the pain of splitting shared expenses in groups — no more spreadsheets, manual calculations, or awkward “who owes what?” conversations. It’s built for friends, couples, roommates, and travel groups who want to scan a receipt, split it fairly, and settle up fast.
