FAQ

Tap tempo feels off by a beat or two.

BPM is the median of your tap intervals, so it needs at least four taps to settle. Keep tapping through a full bar; the reading tightens as it goes. Reset clears the buffer.

Audio detection returned the wrong BPM.

Check the half/double-time alternatives shown beneath the main reading — tempo detectors often lock onto 2× or ½ of the true tempo. Low confidence usually means the excerpt had little transient content; try a section with a clear kick.

Key detection disagrees with my DJ software.

Key detection is statistical. Compare the runner-up key and the chroma bars; tracks with heavy modulation or few tonal elements are inherently ambiguous. The Camelot wheel lets you correct the key with one tap.

Does the app send my audio anywhere?

No. All analysis runs on your device using Apple’s Accelerate framework. Nothing is uploaded and no account is required. See the privacy policy below.

Yes — email us with your iOS version, device and steps to reproduce. Screenshots help.
