Studio51 Song Analysis · effective August 29, 2026

Studio51 Song Analysis is a paid iOS app from Studio51. It compares an original recording you upload to a features-only index of past year-end singles and albums. It is not a chart-rank or hit-probability predictor.

What stays on your iPhone

• Your audio file is chosen on device and analyzed on device. It is not uploaded to Studio51, mix2, or any server.
• There is no microphone, no account, no sign-in, and no tracking SDK.
• Reports live in the app on that iPhone. We do not receive a copy.

What the app does fetch

When you have a network connection, the app may refresh a public comparison index (tempo, key, loudness, and similar features, plus public names of year-end recordings). That index is features-only. It does not include commercial audio.

Purchases

The app is sold as a one-time App Store purchase. Payment is handled by Apple. We do not see your card details.

Children

The app is not directed at children under 13. Do not upload recordings you do not have the right to analyze.
