Free calculators, nothing to install.
Each tool solves one specific calculation nobody does in their head. They are free, need no signup, and run in the browser. The app is for tracking a split over time, not for doing the maths.
Who owes what?
Enter your group's expenses, get who owes what to whom, and the shortest list of transfers that settles everything.
The minimum number of transfers to settle a group

Unequal rooms should not cost the same. Get a defensible split instead of dividing by the number of flatmates.
Each tenant's rent share based on room size, floor and amenities
See the use case : Handling flatshare expenses without a spreadsheetGroup weekend
Rental, groceries and fuel for everyone, lift pass and dinner for some, two people arriving on Saturday. The one calculation nobody does in their head.
Each person's share when people stay different nights and skip different activities
See the use case : Shared expenses for a weekend with friendsUneven expense shares
A couple counts as two, three people had no alcohol, someone left before dessert. An equal split would be unfair.
A split with weights, exclusions and couples counted twice
See the use case : Splitting a night-out bill with friendsShared expenses spreadsheet
A spreadsheet that actually works, free to download, no signup. Plus what to know before it dies after three weeks.
Nothing, deliberately: it is a ready-made template, not a calculator
The maths is done. Now what?
A one-off calculation settles an evening. For a trip or a flatshare, expenses need tracking as they happen, by everyone, without chasing anyone. That is what the app does.
