Who paid, who owes, how much.
Mutual Ledger keeps your flat's shared spending in one place. Log an expense, pick who it's for, and the app splits it and keeps every balance up to date. No notebook, no group-chat maths.
What it does
The shared-costs book your flat actually keeps.
- Spending
- See who spent what
Every shared purchase sits in one list with who paid and how much, so the monthly total is never a guess.
- Even splits
- Split between the right people
Choose who an expense is for and it's divided equally between them. The flatmate who wasn't there for takeaway isn't charged for it.
- Balances
- Any two people, one tap
Pick two flatmates and see exactly who owes whom and how much, with every shared expense between them already counted.
- Settlements
- Record it when you settle
When someone pays back, log the settlement and the balance updates by itself. Nobody has to cross anything out.
How it works
One receipt, split fairly, done.
- Add the expense. Enter the amount and who paid for it.
- Choose who shares it. Tick the flatmates it applies to. The app divides it equally.
- Check a balance. Tap any two people to see where they stand.
- Settle up. Record the payment and the balance goes back to zero.
Why roommates use it
Less arguing about money at home.
- No manual sums. Totals and debts are worked out for you.
- One source of truth. No more scrolling back through chats to find who paid for what.
- Fair by default. Equal splits between exactly the people involved.
- Your data stays on your device. No accounts, no ads, no tracking.
Keep the flat's books straight.
