Before you press play.
Does it save or upload my audio?
No. The live audio is analyzed on your device. Saved sessions contain statistics, not recordings.
Can I use it without an account?
Yes. There’s no Just BPM signup or login. Purchases use your platform’s store account, and device-verification records manage the free allowance with your permission.
What if a rhythm reads at half or double tempo?
Some rhythms have more than one plausible pulse. Choose the right instrument profile, tap your intended tempo, or use a target to help the detector follow it. Results depend on the rhythm and audio conditions.
Does it keep listening in the background?
No. Live monitoring is a foreground activity. It stops safely when the app is backgrounded or the microphone is interrupted, preserving the captured statistics.
Which devices will it support?
iPhone and iPad are the first App Store release. The Android version is in development. We’ll publish download links when each release is available.
