Local-first routine planning

Rhythm

Rhythm helps you track plans that do not fit a normal calendar: phased medication schedules, training blocks, recovery routines, study plans, and any routine where the rules change over time.

Built for plans that change shape.

Traditional calendars are good at fixed events. Rhythm is designed for staged plans where the frequency, dose, workload, or reminder timing changes by week, month, or day.

Phased schedules

Create routines with multiple phases, custom durations, reminder times, and changing instructions.

Today-first view

See what matters today without scanning a calendar grid or recalculating which phase you are in.

Local-first by default

Use the core app without an account. Sign in only when you want cloud backup, sync, or AI assistance.
