What's the difference between percentages and weights?

Percentages are absolute (sum = 100%). Weights are relative: if you assign 2 to one person and 3 to another, the app computes 40/60 automatically. Simpler when you add or remove participants — you don't need to readjust the others.

Can I change the mode per expense?

Yes. Each expense has its own mode, set at entry time. You can have a count with 80% of expenses in equal shares, 15% in exact amounts, and 5% in percentages — no trouble.

In a flatshare with different rents, what do I do?

Set the count's default split in Weights or Percentages mode. If A pays 60% of the rent and B 40%, all subsequent expenses follow that rule automatically unless you override.

What's the default mode?

Each count has a default split mode, chosen at creation. When you add an expense, it follows that mode, but you can always override on the fly.

How does the app handle rounding?

All arithmetic is in integer cents. When a division creates a remainder (3 people, 10 €, each 3.33 €), the app distributes the leftover to the first participants — 3.34 € for one, 3.33 € for the two others. Zero cent lost.

Is this included for free?

Yes. All four modes are available in the free tier, with no usage limit.

Four ways to split an expense.

Split modes

On each expense, you pick how it splits between members: equal shares for the classic case, exact amounts when everyone ordered different things, percentages for specific cases, or weights to keep things proportional without fighting the math. Four modes, one per expense, freely mixed in a single count.

How it works

All modes use the same integer-cent arithmetic — no lost rounding, no missing cent. Each expense keeps its own mode, independent from the others in the count.

01Step 1

Equal shares — the default

Check participants, the amount is split evenly among them. Ideal for a group dinner or the weekly flatshare grocery.

02Step 2

Exact amounts — when each person knows what they ordered

Each person enters exactly what they should pay. The sum must match the total expense, otherwise the app rejects the entry. Perfect when each person ordered differently.

03Step 3

Percentages — for specific cases

Assign a percentage to each participant, total must be 100%. Useful when one member carries a defined share (60% / 40% for a couple, for example).

04Step 4

Weights — to stay proportional

Each participant gets a weight (2, 3, 5...), the app computes the proportional share automatically. More flexible than percentages: you describe the roles, not the numbers.

Honestly

What you should also know.

No overblown promises. Here are the real limits of the feature, to avoid surprises.

All four modes mix within a single count — each expense picks its own mode independently.

In amounts mode, the sum must exactly equal the total expense. If you're off by a cent, the app blocks entry.

In percentage mode, the sum must be exactly 100%. The app helps you balance if you're close.
