Best IOU and expense-splitting apps in 2026
Shared rent, group trips and the tenner you lent a friend all deserve a clear record. Here are ten apps that track IOUs, split costs and help everyone settle up.
AI generatedThe best expense splitting app keeps money between friends, housemates and partners from getting awkward. Someone covers the groceries, someone else pays for the taxi, and a month later nobody is sure who owes whom. An IOU app or bill splitting app keeps a running record so balances are clear and settling up takes one payment instead of an argument.
We started from the apps that come up most often in 2025 and 2026 lists of Splitwise alternatives and kept only those that are actively maintained. We compared how each app handles group trip expenses, personal loans between two people, uneven shares and multiple currencies, how it works out who should pay whom, whether it works without sign-up or offline, and what the free version limits. Support for iPhone, Android and the web, plus privacy, also played a part.
At a glance

#1 · Best for Personal loans and group costs in one place
Listub Debt Ledger
IOUs, contracts and group splits together
Debt Ledger is an IOU app and expense splitter with three modes: Solo for a private record only you keep, Contract for a one-to-one loan agreement both people accept, and Group for splitting bills with friends or roommates. In a contract, the terms, date and acceptance are locked when the room is created, so nobody can change the deal later. Group costs split evenly or by exact amounts, everyone sees a net balance, and part payments update the running balance without rewriting the history. The Galveo AI assistant can log a new expense from a quick sentence.

How to choose
Think about what you are tracking. An expense splitting app for roommates or a group trip needs to handle many people paying for many things, and the key feature is a simplified settle-up that reduces the number of transfers. A personal loan tracker is different: you want a clear record of the money owed, the date and any repayments, ideally agreed by both people so there is no dispute later.
Then look at the practical limits. Splitwise caps how many expenses free users can add each day and keeps receipt scanning and currency conversion for Pro, which is why many people look for a free Splitwise alternative. Some apps skip accounts entirely, which is convenient for a one-off trip but less useful for long-running balances between couples or housemates. Check that everyone can use the bill splitting app on their own iPhone, Android phone or browser, and decide whether you want the app to handle payments or simply keep the record.
