Questions
How does it find the tempo?
It measures how the sound changes: drums, plucked notes and sung syllables each make the spectrum jump. It then looks for the time between jumps that repeats most regularly, between 50 and 220 BPM, and refines it over several beats.
Why does it say “or 64 BPM”?
Many songs can be counted at two speeds: a hip-hop beat at 90 BPM is also a 180 BPM beat with half the kicks. The detector picks the likelier reading and names the other, so you can choose the one that matches how you count.
How reliable is it?
Very, for music with a steady beat (pop, rock, dance, hip-hop). Songs that speed up and slow down, classical music and ambient pieces have no single tempo; the detector then says it isn’t sure. Tapping along gives you a second opinion.
Are my songs uploaded anywhere?
No. Your songs are opened and processed on your device, and the results are saved straight back to it. Nothing is uploaded. How to check.
Is it free? Do I need an account?
It is free to use and there is nothing to sign up for. There are no watermarks and no daily limits.
