Air Tuner

Air Tuner makes guitar tuning simple and direct.

Open the app, allow microphone access and play a string. A clear light meter shows whether the note is flat, sharp or in tune.

• Chromatic tuning displays the current note, including alternate tunings.
• Standard tuning, alternate presets and custom six-string targets.
• Six-string strum inspection on iPhone and iPad, for standard guitar tuning. Detected strings appear together; quiet or masked strings may require another strum.
• Native iPhone and iPad apps; iPad supports portrait and landscape.
• Free core tuning, no ads and no account required.
• CLASSIC is free. Each of the seventeen paid skins has a separate free minute every day, or can be purchased for unlimited use.
• Trial time counts only while the tuner is visible, pauses in settings or the background, and resumes after reopening. When time runs out, the app returns to CLASSIC. Daily trial usage stays on each device.
• The October 2026 collection unlocks its fixed 15 skins, including SUNSET GLASS. A, B and C and future skins are not included.
• Optional tips support development and unlock no extra features or trial time.

Audio is processed locally and is not uploaded or saved by the production app. Tuning and previously unlocked skins work offline. Purchases, price loading and restoring purchases may require an internet connection. Apple processes all purchases; prices are shown in your local storefront.

Apple offer codes can be redeemed on iPhone or iPad. Daily trial usage does not sync between devices. Test recording and automatic music transcription are not part of the production app.
