Training timer
HoldTempo — Hangboard Timer
Create your own hangboard work and rest intervals, run repetitions and sets, and keep a private session log. Timing runs while the app is visible; leaving the app pauses it until you explicitly resume.
Free to download. Pro is optional.
HoldTempo is a timer and log. It does not provide coaching, diagnosis, pain interpretation, medical guidance, or personalized load recommendations.
Optional Pro
Pro lets you create, reorder and reuse Programs built from your own timers, with optional private iCloud sync for Programs. Monthly and Annual subscriptions renew automatically; Lifetime is a one-time purchase. Single timers, templates, session history and recovery stay free.
A practical workflow
When to use HoldTempo
- Enter a work/rest pattern you already chose.

Choose this app when its documented scope fits the task you want to keep on your iPhone. The free web resources below are independent alternatives for a single worksheet or calculation.

Before you choose
Does the timer continue when I leave the app?
Timing runs while HoldTempo is visible. Leaving the app pauses it until you explicitly resume.
Does it recommend training loads or routines?
No. You choose the pattern. It provides no coaching, pain interpretation, diagnosis or personalized loading recommendations.
Are the browser calculator and app connected?
No. The calculator checks duration arithmetic only. It does not import a pattern, sync a session or run an active workout timer.
