For bugs, including the following helps us investigate faster:
Microphone access may be off. Open the Settings app → Hum Memo → turn on Microphone.
Only on your device — they are never uploaded. Deleting the app deletes them too, so save important songs with the export button at the top right (for example, to the Files app).
Bluetooth adds a large delay, which is corrected automatically after recording. If a gap remains, adjust it under Rec setup → Manual timing adjustment. Wired earphones give the most accurate timing.
Choose “Open Overdub” in Rec setup. It reduces the existing tracks playing from the speaker leaking into your take. A speaker volume of about 40–70% works best.
Use Instrument/MIDI to convert a recorded track into an instrument sound, or export it as a MIDI file you can edit in a music app. Humming clearly, one note at a time, improves accuracy.
Tap the song name at the top left → Songs, then use the trash button. Deleted songs can’t be restored.
