Step Timer is a basic timer for mapping out simple or complex multi-part timing sequences in sound, lighting, projections, animation, video and film.

Tap Start to start the timer. Each time you tap Mark it will record both the total elapsed time and the interval since the last mark. Set the accuracy to 1/10 or 1/100 of a second, or to 24, 25, or 30 frames per second. The timing log can be copied and then pasted into another app for saving or sharing.

Tap the big button in the Tempo view in time to your music to display beats-per-minute, as well as the inverse: time-per-beat, which is critical for setting cue or effect timing to match the music.

Step Timer is a must for lighting, sound and projection design, video and animation, or any work where a sequence of action steps must be timed accurately, or synchronized to a music tempo.

Ratings and Reviews

Great App for using on shoot!


just needs the bottom screen to save the markers for when you stop the filming. but overall worth the 99 cents! Thanks

Simple and highly useful


This is straightforward and easy to use, does exactly what it says with no fuss.

I have used it now for timing sequences for an off-Broadway musical, an opera and several one-off band performances and it made each of those tech days significantly less stressful.

Thank you for another useful tool.
