PhaseKit

Flexible sequence timers for routines that need clear structure.

PhaseKit helps you build interval routines for workouts, breathwork, mobility, study blocks, and repeatable daily flows. Create custom sequences, group steps, save routines, and start from the timer that matters now.

Core timer building, playback, grouping, and saved routines are free to use.
An optional one-time Support Developer purchase unlocks cosmetic app color customization.
Customers who bought the paid version before the free transition can use Restore in the app settings and do not need to pay again for the supporter unlock.

Privacy-forward by design: PhaseKit works primarily on-device, does not include third-party ads or analytics SDKs, and does not track you across apps or websites.

What PhaseKit Does

PhaseKit focuses on customizable routines, grouped timer flows, saved presets, and a running experience that stays readable while your sequence is active.

Free Core Features

Everything needed to build, save, and run routines remains available without payment.

Optional Support

The one-time Support Developer purchase is not a subscription. It unlocks color customization and helps keep the app maintained.
