Yes. Maelzel declares the iOS background-audio capability, which is what lets a metronome keep going with the screen off or while you are in another app. If it stops, check that the iPhone’s silent switch is not muting it and that another audio app has not taken the session — starting a track in another app interrupts the click, and Maelzel shows Paused — interrupted rather than pretending it is still counting.
That delay is the headphones, not the app: every wireless audio link buffers, and nothing in software can remove it from the sound. What you can do is move the picture to match the sound. Open Preferences → Playing → Visual lead and raise it until the flashing beat lines up with what you hear — 100–200 ms suits most Bluetooth headphones. The setting moves the on-screen beat only; it never changes the timing of the click itself, and it does nothing on wired headphones or the built-in speaker, where you should leave it at zero.
No. Start the free three-day trial explicitly. It lasts 72 hours from the original trial purchase and never automatically charges or renews. After it ends, continued metronome and trainer use requires a separate one-time lifetime purchase. Apple handles refund requests.
Open Preferences → Maelzel access and tap Restore purchases, also available on the purchase and first-run screens. Use the same Apple Account you purchased with. Restoring does not restart the trial. If access is still missing, email us with the purchase date.
Every feature: the complete metronome, tempo ladder with confirmation and memory, configurable and growing gaps, random mute, all offbeat presets, polyrhythms, songs, setlists, Live mode and your complete practice log. Lifetime access includes the same features, without a time limit.
When the trial ends, your records stay saved and exportable. Data settings, backup export/import, restore and legal information remain available. Reinstalling, resetting data, restoring purchases or importing a backup does not restart the trial.
Set a start tempo, a target and a step, and Maelzel climbs: it holds each tempo for the bars you chose. Auto keeps climbing. Confirm pauses at each rung and asks whether it was clean; Again repeats it and Clean moves up. If you keep missing the same rung it stops, and the next ladder on that piece proposes a start just below where you stalled.
The click plays for a number of bars and then drops out while you keep playing. When it returns, you can hear whether you drifted. Set both lengths, grow the gap as you go, and mute bars at random. All options are included during the trial and with lifetime access.
Yes, with active trial or lifetime access. Build a setlist and tap Go live for the song name, tempo, beat and Previous / Play / Next controls. The screen stays awake and supports landscape.
Preferences → Data → Export backup builds a JSON file and hands it to the iOS share sheet — save it in Files, iCloud Drive, or anywhere you will find it again. Import backup reads the same file back and replaces what is on the phone, so it asks you to confirm first. There is no automatic sync; the backup file is the copy.
No, and it cannot. There is no microphone access anywhere in the app: no tuner, no recording, no pitch detection, no beat following. Maelzel never asks for microphone permission, so you will never see that prompt. Its microphone purpose string exists only because Apple requires one when an included audio library contains recording code.
Metronome use requires active trial or lifetime access; offline access depends on known purchase information in the app’s cache. RevenueCat automatically checks purchase status at startup, even before a purchase. Starting a trial, buying, restoring, and fetching current offers or fresh purchase information require a connection. Expo may also automatically check for and download updates. These requests do not upload your songs or practice log. See the Privacy Policy.
Delete the app to remove local songs, setlists, pieces, sessions and settings. Manage exported files and operating-system backups separately. Removing the app does not delete purchase records held by Apple or RevenueCat or restart a trial. For provider-data or support-information requests, see the Privacy Policy or email us.
Email bogdan.tsiganiyk@gmail.com. Your iOS version, device model, and what you were doing when it happened all help. If the timing sounded wrong, tell us the tempo, the meter, the subdivision, and whether you were on the speaker, wired headphones or Bluetooth — those four answers narrow it down faster than anything else.
