Two phases.
One clean timer.

A minimalist interval timer for hangboard and grip training. Set work and rest independently. Run your protocol. Don't think about anything else.

Core

Two phases, timed independently

Set a work duration and a rest duration. They run back to back, cycling through your repeat count. Perfect for 7-second hangs with 3-second rests, or any protocol your training demands.

Phase 1 · Work
7s
Phase 2 · Rest
3s

Repeats

Finite or endless

Set 1–99 repeats for a structured protocol, or enable infinite loop mode for open-ended sessions. A repeat counter keeps track during your workout.

  • 1–99 repeat count
  • Infinite loop mode
  • Repeat counter shown during run

Choose a different sound cue for each phase. Know instantly whether you're starting work or rest without looking at the screen.
