Tone is a chromatic tuner that does one thing well: tell you the pitch — clearly and instantly. No ads. No accounts. No sign-up. No analytics. Open it and play. WHAT IT DOES • Hears any note from your instrument and shows the note, octave, and how many cents sharp or flat you are. • Reads like a real tuner: an analog needle that swings with the pitch and stands upright the moment you're in tune. • Turns a single accent color the moment you're in tune, with a gentle haptic tap — keep your eyes on the instrument, not the screen. • Adjustable reference pitch: A4 from 415 to 466 Hz. • Reference tone (tuning fork): switch to FORK mode, pick any note and octave, and play a clean sustained tone to tune by ear — no microphone needed. PRIVATE BY DESIGN Audio is processed entirely on your device and is never recorded, saved, or sent anywhere. Tone works fully offline and contains no third-party tracking. DESIGNED FOR iOS A native interface built like a piece of hardware, with VoiceOver and Dynamic Type support. Tune a guitar, violin, cello, wind instrument, or anything with a clear pitch. ## Key features - Instant pitch detection - Analog needle display - Color-coded in-tune indicator - Adjustable reference pitch - Tuning fork mode - Offline functionality - Privacy-focused design ## Frequently asked questions about Tone ### What instruments can Tone tune?

Writing a review, sharing Tone, help and support, and the privacy policy are all in one place. • A switch to turn review reminders off, if you have already reviewed Tone or would rather not be asked. Changed: • The header now moves the tuner / reference toggle onto its own line at large text sizes, so nothing gets clipped. ### 1.2.0 — 2026-08-14 Changed: • A new app icon. The needle and note now stay readable at the size the icon is actually shown at — on the Home Screen and in search. ### 1.1.1 — 2026-08-13 Fixed: • Tone now appears in Japanese on Japanese-language devices. The translation was already in the app but never showed — including for VoiceOver. The microphone permission prompt is now in Japanese too. ### 1.1.0 — 2026-08-01 New in this version: • A share button on the tuner face, for passing Tone along to someone else. Also fixed: • The tuner face no longer bounces when you drag it. • Switching from the reference tone back to the tuner now starts listening without a gap. • Leaving and returning to Tone in quick succession no longer leaves the tuner not listening. ### 1.0.1 — 2026-06-27 Bug fixes and reliability improvements: • The microphone now starts reliably right after you grant access, and recovers on its own after calls, Siri, or unplugging headphones. • Tuning prefers the built-in microphone over a Bluetooth headset for more accurate pitch. • Other apps' music or podcasts now resume after you leave Tone. ## Related topics [tone tuner](https://appshunter.io/ios/topics/tone-tuner) · [twelve-tone tuner](https://appshunter.io/ios/topics/twelve-tone-tuner) · [g strings tuner](https://appshunter.io/ios/topics/g-strings-tuner) · [tone reader](https://appshunter.io/ios/topics/tone-reader) --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
