Build custom routines for workouts, breathwork, mobility, or study blocks — save them once and start them again in seconds. Stop fumbling with a stopwatch mid-set. PhaseKit builds interval routines that hold their shape through an actual workout, breathwork session, mobility flow, or study block — then brings back the one you need in seconds. Create custom sequences, group steps into repeatable rounds, save routines you'll reuse, and jump straight into any saved timer without rebuilding it from scratch. Key features: • Ready-to-run templates: Tabata, 30/30 intervals, box breathing, and focus sessions • Build custom interval sequences with grouped steps • Save and reuse routines for workouts, breathwork, mobility, or study blocks • Start from any timer in a routine, not just the first • Spoken 3-2-1 countdown and a gong between steps • Timers from one second up to 24 hours • iCloud sync for saved routines across your devices • Available in English, Spanish, German, French, Italian, Hindi, and Thai • No account required • No third-party ads or analytics Core timer building, playback, grouping, and saved routines are completely free. An optional one-time Support Developer purchase unlocks cosmetic app color customization and helps fund ongoing development — it's not a subscription, and it never limits the free features. Customers who bought the paid version of PhaseKit before it became free keep the supporter unlock automatically.
