Cosum: Split Expenses
Log what the group spent, see who owes whom, and settle in fewer transfers.
About Cosum: Split Expenses
Cosum keeps track of what a group spends together and answers one question at a glance: who owes whom, and how much.
A trip, a shared flat, a dinner that four people paid for in pieces. Cosum records it and closes the account correctly.
NOBODY ELSE HAS TO INSTALL ANYTHING
Add the people you are splitting with by name. They do not need an account, a phone number, or the app. One person can record the whole group's spending, and the others simply get told what they owe.
If someone does want to join later, they open the invite link, pick their own name from the list, and everything already recorded under that name becomes theirs. Nothing is lost and nothing is entered twice.
AN EXPENSE IN UNDER FIVE SECONDS
Nobody wants to open an app at the dinner table. So every default is already filled in: you are the payer, the split is the one you used last, and the keyboard opens on the amount. Category is optional. Type the number, done.
ONE SENTENCE, NOT A SPREADSHEET
The home screen tells you where you stand — "You owe Alex 240" — and the breakdown is one tap away when you want it.
Before anyone transfers anything, Cosum simplifies the debt. Five people with ten tangled IOUs settle with three transfers instead of ten.
IT OPENS WITHOUT A SIGNAL
No blank screen, no endless spinner. The last synced state is there and the app tells you it is offline. Reading works everywhere; adding an expense needs a connection.
WHAT COSUM IS NOT
Cosum is a ledger. It does not move money, hold funds, or connect to your bank. Every transfer you agree on happens between you and the other person, outside the app. The balances are a calculation from what you entered.
FREE, AND PREMIUM IF YOU NEED MORE
Free covers 5 active ledgers, 10 people per ledger and 6 entries a day, with a single banner on the summary screen.
Premium removes the banner, lifts the ledger and daily limits, and takes a ledger up to 50 people. Monthly or yearly, cancel any time from your Google Play account.
Available in 18 languages.
