Klok In
Hours and invoices for contractors, 2026
Available on
App Store
A timesheet for people who bill by the hour and forget to write things down. Log what you just worked on in two taps, or start a timer that keeps counting on your Lock Screen.
When it's time to bill, pick a client and a range, and Klok In builds the invoice from their rate, your expenses and tax, then keeps track of who has paid.
Every client, their own rate
Rates, currencies and colours per client, and a day that can switch to just one of them.
Invoices, not just timesheets
Six templates, sent as PDF, Word or CSV, with a history of what's outstanding and paid.
A timer on the Lock Screen
A Live Activity in the Dynamic Island that keeps counting with the app closed.
Insights, all on the phone
Hours against the last period, earnings and unbilled time, with no account and nothing to sync.
