A metronome you run with your voice, so your hands never leave the instrument. Say "start" to begin, "faster" to speed up. No tapping, no stopping mid-phrase. The app listens through its own microphone and recognizes speech on your device, so it works right away. There is no need to turn on iOS Voice Control or any Accessibility setting. ON IPAD AND APPLE WATCH On iPad, stand it on your music stand: the beat and tempo are big enough to read from a metre away, and the beat stays in view next to your score app in Split View. A Bluetooth page-turn pedal changes the tempo and starts or stops the click. On Apple Watch, feel the beat as silent taps on your wrist, with a stronger tap on beat one. Turn the Digital Crown to change the tempo. It runs without your iPhone, and the complication starts your last tempo with one tap. Wrist taps go up to 200 BPM. TALK TO YOUR METRONOME "start" and "stop" "faster" and "slower" move 5 BPM, "up" and "down" move 1 "tempo 120", or just a number, jumps straight to it "double" and "half" "quarter", "eighth", "triplet", "sixteenth" for subdivisions "louder", "quieter", "mute" Forget a command? Say "help" and every phrase you can use appears on screen THE FULL METRONOME IS FREE Meters from 1 to 8 beats, with a stronger click on beat one Quarter, eighth, triplet and sixteenth subdivisions Three ways to watch the beat: bounce, orbit and ring Tap tempo: tap the big number in rhythm to set the BPM Timing check: tap the orbit ring as you play and see how close you landed The screen stays awake while it plays, and your last tempo and meter are remembered NOT MY TEMPO PRO Practice mode: a speed trainer that adds a few BPM every few bars until you reach your target Accent editor: set every click in the bar to high, low or silent, and save a preset per song Chromatic tuner: tune up before you start Pro is a yearly subscription with a free trial, or a one-time lifetime purchase. ACCESSIBILITY If you rely on iOS Voice Control, switch the app's own mic off and drive it by button name instead. Controls carry VoiceOver labels. SUBSCRIPTION DETAILS The yearly plan renews automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel it in Settings > Apple Account > Subscriptions. Lifetime is a single one-time charge. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://m1zz.github.io/HandsFreeMetronome/privacy.html
