Appoggia

About

Appoggia trains your ear and your pitch. It plays a note, listens to you sing it back and shows how close you are and how steady you hold it, in real time and hands-free.

• Your Range finds the lowest and highest notes you can keep steady and makes them the app's range.
• Warm Up climbs your range by half steps and back down.
• Sing the Note: hear a random note, sing it back, hold it in tune and the next one plays.
• Patterns: hear a short pattern, sing it back.
• Stats: practice, level and precision over time.

For iPhone and iPad.

Privacy Policy

Effective 14 November 2026

Appoggia is made by TalonAI LLC. The app does not collect any data. It has no account, no ads, no analytics and no tracking, and it does not connect to the internet.

Microphone

Appoggia uses the microphone to hear your singing. The sound is analysed on your device in real time and is not sent anywhere.

Audio is saved only if you turn on Settings → Diagnostics → Record sessions (off by default). Recordings are kept on your device, in the app's folder in the Files app, and the oldest are removed automatically. They leave your device only if you share them yourself.

Data on your device

Your settings, your range and your practice history are stored on your device only. We cannot see them. Deleting the app deletes them.

Children

Appoggia collects no data from anyone, including children.

Changes

If this policy changes, the new version will be posted on this page with a new effective date.
