Free CrossFit Timer for iPhone

The ad-free timer that looks and works like the clock at your box

A gym clock in your pocket

Box Timer was built to replicate the large wall clock at a CrossFit box. The digital display, the beeps at round transitions, the simple controls — everything is designed so you can set up a WOD in seconds and focus on the workout, not the app.

Whether you are doing an AMRAP at the gym, an EMOM in your garage, or a For Time workout while traveling, Box Timer handles all the standard CrossFit timer formats.
