Div/Sum

Div/Sum is a free AI-powered bill-splitting and group-expense app for iOS and Android. It turns a photo of a receipt into a fair, personalized bill split in under a minute, helping groups calculate what everyone owes and request payment without calculators, spreadsheets or awkward conversations. Instead of entering every purchase manually or dividing the total equally, users simply photograph the receipt. Div/Sum’s AI-powered OCR technology reads the individual items, prices and quantities automatically, including information from crumpled and handwritten receipts. How Div/Sum works:

1. Scan the receipt Take a photo of a restaurant, bar, supermarket or other receipt. Div/Sum extracts the line items, quantities, prices and total, removing the need for manual data entry.
2. Add the people involved Select existing friends, create a group or add guests on the spot. Div/Sum remembers regular group members, making future bill splits faster for friends, couples, housemates and work teams.
3. Assign individual and shared items Tap an item and assign it to the person who ordered or purchased it. Participants can identify what belongs to them, while shared dishes, drinks or household products can be divided evenly between selected members of the group. This item-level approach is particularly helpful when people have ordered different meals, shared only part of the table or purchased groceries based on different dietary needs and preferences.
4. Calculate everyone’s exact share Div/Sum calculates how much each participant owes, including their assigned items and share of anything consumed together. Taxes, tips and service charges can be distributed proportionally, so each person contributes fairly rather than paying an equal part of a bill they did not create. The person who originally paid can be selected as the payer. Their own share is marked as settled automatically, while payment requests are prepared for everyone else.
5. Request payment Generate personalized payment requests through Revolut, Venmo or PayPal. A clear text summary can also be copied and shared through any messaging app. Friends do not need to download Div/Sum or create an account simply to view their total and pay back the person who covered the bill. This makes the process practical even when splitting expenses with new acquaintances, travel groups or people who use different devices. Built for real shared-expense situations Div/Sum can be used for:
