MagicBPM: Tempo & Metronome

Know the tempo of what's playing. And its name.

MagicBPM listens through your iPhone's microphone and measures the BPM (beats per minute) of whatever's playing, in real time. Point it at a speaker, an instrument, or a record, and watch the tempo lock in. Tap Identify song and Apple's music recognition puts a name to the track. When you need to keep time yourself, switch to the built-in metronome, on the phone or on your wrist.

FIND THE TEMPO
• Live BPM detection: a dual-engine detector (autocorrelation + onset peak-picking) tuned for music with a steady beat, with an indicator for when it is solid.
• Half and double tempo: some songs can be felt two ways. Flip the reading to half or double time with one tap under the number, and MagicBPM hints which is likelier.
• Live tempogram: a scrolling heatmap of tempo over time. See the beat strengthen, drift or shift between sections at a glance.
• Tap tempo: nothing playing? Tap along and MagicBPM averages your taps into a steady BPM.
• Dial it in: set a tempo range, pick a detection engine, and tune the noise gate to match your room.

NAME THE SONG
• Tap Identify song while you listen and MagicBPM names what's playing, powered by Apple's music recognition.
• See the title, artist, and cover art right next to the live BPM, and open the song in Apple Music with a tap.

KEEP THE BEAT
• Built-in metronome: set a tempo by tapping, typing, or nudging it ±1, then press play for a rock-steady click. Eight time signatures with an accented downbeat, and it keeps playing even with the ringer on silent.
• Keeps going in your pocket: the click carries on when you leave the app or lock the screen, and a Live Activity on the Lock Screen and in the Dynamic Island starts it, stops it, and nudges the tempo without unlocking.
• Subdivisions: practice against eighths, triplets, or sixteenths, with the in-between clicks pitched under the beat so you never lose the pulse. Free for everyone.
• Compound time that counts properly: 6/8, 9/8 and 12/8 group in threes, and 7/8 lets you pick 2+2+3 or 3+2+2.
• Vibrate on beat: feel every tick as a haptic tap, with a firmer pulse on the downbeat.

ON YOUR WRIST
• Apple Watch metronome: every beat is a tap you feel, not a click the room hears, so it works on a loud stage and in a quiet house alike. Set the tempo by tapping the number in time or turning the Digital Crown, then drop your wrist and it keeps tapping. Included free with the iPhone app.

PRIVATE BY DESIGN
• Tempo detection happens entirely on your iPhone. Your microphone audio is analyzed in real time and discarded. It is never recorded or uploaded.
• Song identification, when you use it, sends a compact acoustic fingerprint of the sound, never the audio itself, to Apple's Shazam service to name the track.
• Songs you identify are saved to your Detected Songs history on your iPhone and nowhere else. You can clear the list at any time, Pro or not.
• Anonymous usage and crash reports tell us which features get used and which devices struggle to hear a beat. They never include your audio or the songs you play, and Share usage data in Settings turns them off.
• No account, no sign-in.
