Past · present · future
See your money over time.
Know what is available
Available Now is derived from the opening amount and real transactions. It is never a mystery number.
Plan what comes next
Budgets and schedules can forecast a future date without pretending planned money has already moved.
Kind by design
A useful financial tool should respect both your attention and your data.
Clear, not clever
Large numbers, plain language, and a direct path to the next transaction.
Private by default
No bank password, advertising SDK, or third-party behavioral analytics.
Yours to keep
Financial records remain in your Apple environment, with CSV export when you want a copy.
SumKind
A little clarity can be a lot of kindness.
We are preparing the first release for Apple devices.
