Got questions?

How does itemized mode work? expand_more

Itemized mode allows you to list individual dishes and drinks, then assign them to specific people. The app then calculates exactly what each person owes, plus their share of tax and tip.

Can I split unevenly or round up? expand_more

Yes! You can choose to split to the exact cent, or use our smart "Round Up" feature to make the per-person amount a clean dollar figure.

Does it work offline? expand_more

Absolutely. All calculations happen locally on your device. It works in basements, on airplanes, or in remote cabins with zero reception.

Are there ads or accounts? expand_more
