Support
Last updated: August 11, 2026Support for Piyanomini Ars and Piyanomini Manus is handled by email. Write to us and we usually reply within 1-2 working days.
What to include
Tell us which app you are using (Ars or Manus), the app version, your device model and your iOS version. The app version appears near the bottom of the Settings screen, on the line starting with v. If the problem occurs in a particular exercise, add the name of the exercise and the settings you used; being able to reproduce the exact case makes the fix much faster.
Free trial
Each app can be tried in full for 14 days from first use. No card details are requested during the trial, no automatic charge is made when it ends, and there is no subscription. Once the trial is over you can buy the app and carry on where you left off; your practice history stays on your device.
Restoring a purchase
If you changed device or reinstalled the app, tap the Restore link on the purchase screen. A purchase is valid on the devices you use with the same Apple account and for members of your Apple Family Sharing group. If restoring does not work, check that the device is signed in to the App Store with the right Apple account, then write to us.
Microphone and audio
The tuner, intonation and singing exercises request microphone access; if you declined, you can enable it in your device settings. If pitch detection drifts, try a quiet room. Using headphones, so that sound from the speaker does not feed back into the microphone, noticeably improves the result.
Refunds
Purchases are made through the App Store and handled by Apple, and refund requests go to Apple as well. We have no access to your payment details, so we cannot start a refund on your behalf; you can request one from Apple's refund page.
Teachers, schools and suggestions
You are welcome to write about classroom use, student groups and institutional questions. Bug reports, gaps you notice in the content and ideas for new exercises reach the same address; the roadmap is shaped largely by this feedback.
