Accurate 20–400 BPM metronome with meter, accents and subdivisions.
Start the tool with a deliberate click. For tuners, allow microphone access, play one clean note and wait for the reading to settle. Audio is not recorded and samples never leave the device.
Results depend on the microphone, background noise, room reflections and the quality of the played note. This is a practical tuning and practice tool, not laboratory measurement equipment.
