BeatIt! is a program that lets you measure a tempo or heart rate in beats per minute.
Tap a beat with the BeatIt! button, or use the hardware up/down buttons instead.
Choose 2, 4 or 8 beats to tap. The updated BPM-rate appears inverted whenever the last beat is tapped.
That feature prevents from affecting the BPM-rate unconsciously.
If Timeout is checked, the BPM-Rate and the counted beats will be reset if the last tap was 1.5 seconds ago (rates below 40 bpm doesn´t make much sense).
You can use BeatIt! as a timer, if you set the mode to "ms" and disable the Timeout option.
