Feature highlights

Built for reliable daily tracking with a practical blend of local-first and cloud-backed workflows.

Live shift timer

Clock in and out with one primary action while the foreground service keeps timing active and visible.

Smart history editing

Review past sessions and update project names, start times, end times, or remove entries when needed.

Cloud-backed data

Room stores entries locally first, then Firestore sync keeps your data available across installs and devices.

Anonymous auth

Automatic anonymous sign-in secures user-scoped cloud data without adding account setup friction.

Configurable settings

Set default project labels, pay rates, pay periods, and work days to match your routine.
