A minimalist interval timer for hangboard and grip training. Set work and rest independently. Run your protocol. Don't think about anything else.
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.
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.
Choose a different sound cue for each phase. Know instantly whether you're starting work or rest without looking at the screen.
A black screen, a large countdown, and a color-coded progress ring. Nothing else. Each phase has its own color so you always know where you are at a glance.
Add a title and notes to each timer. iCloud sync keeps your protocols up to date across all your devices automatically, with no account required.
Built for one thing: running your protocol without friction.
