Does this work on iPhone Safari?

Yes. Use Safari, allow mic access, and keep the tab open. Add to Home Screen if you want a home-screen icon without a separate install.

Is a phone mic good enough for band rehearsal?

For steady tones and warm-ups, yes for most students. Hold the phone near the bell, play at a solid mezzo-forte, and use a quieter room when you can.

Why did the tuner stop when I switched apps?

Mobile browsers often pause audio and the mic when the tab is in the background. Keep Safari in front, or use the iPhone app when you need to leave the page.

The tab is the app, until it isn’t

If you only need to check pitch for five minutes, open the link, allow the mic, play a note. You do not need another App Store listing first.

Use Safari on iPhone and iPad. Chrome is fine on most Android phones. No account for the web tuner.

iPhone and iPad

Open /tuner in Safari. Tap Start, allow microphone access, and hold the phone near the instrument. Watch cents settle near 0. Optional: Share → Add to Home Screen for a fullscreen icon without installing a separate tuner app.

Safari for reliable mic permission on iOS
Keep the tab in the foreground while you tune
Quiet the room when you can — soft tones can read flat
A440 default; nudge A for ensemble pitch

Android

Open the same URL in Chrome. Allow the mic when prompted. Works for band instruments, guitar, and voice when the room is quiet enough for the phone mic.

When to use the iPhone app instead

Stay in the browser for a quick check. Switch to the iPhone app when you want record, a journal, written transposition (Bb/Eb/F), HYKOM paths, and MM Mode. The tuner stays free; Pro is for the deeper tools.
