MagicBPM vs Underbeat

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: tuned for music with a steady beat, with an indicator for when the reading is solid. • Precise: a second reading, taken from the last 15 seconds your iPhone heard and shown with the beats it found. When it finds no steady beat (speech, a quiet room), it says No steady beat. It runs on your iPhone, with Apple's music analysis on iOS 27 and MagicBPM's own model before that. Phones too slow to run it are not offered Precise. • Half and double tempo: some songs can be felt two ways. Flip the reading to half or double time with one tap, 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. NAME THE SONG • Tap Identify song while you listen: the title, artist and cover art appear right next to the live BPM, and a tap opens the song in Apple Music. 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. 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. 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. FREE, WITH AN OPTIONAL PRO UPGRADE MagicBPM is free and supported by ads. MagicBPM Pro is a single one-time purchase. No subscription, ever. Pro adds: • Live song detection: songs are identified automatically as they play. Hands-free, no tapping. • Detected Songs history: every song you identify is saved on your iPhone with its BPM and artwork. Pro unlocks the list and opens any track in Apple Music. • Precise in History: as you listen, each song gets its precise BPM and a tempo curve, and on iOS 27 its key. • Twelve metronome sounds: woodblock, claves, cowbell, hi-hat, shaker, triangle and more. Preview any of them before you buy. • Ad-free: removes every ad from the app. Restore your purchase anytime on any device signed in to your Apple Account. 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 on your iPhone. Pro also syncs them through your own iCloud. Never sent to us. Clear them 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. Questions or feedback? Email support@magicbpm.com.

Underbeat is a metronome that plays alongside your music instead of interrupting it — for practising an instrument, and for running. Start a track in Spotify or Apple Music, start Underbeat, and the click sits underneath it. No ducking, no pausing, no switching apps. FOR MUSICIANS Practise to the recorded track rather than to a click in isolation. The Music group starts at 80, 120 and 90 BPM, in 4/4 and 3/4, and a warm wooden click. FOR RUNNERS Hold a cadence over a playlist for the length of a long run. The Running group starts at 160, 170 and 180 steps per minute, with a rim click chosen to cut through music in open air without being loud. One engine underneath both — the same timing, the same mixing. What differs is the preset group you switch to, and each carries its own sound and its own volume. PRESET TEMPOS Switch tempo with one tap. A piece that moves between sections, or an interval that changes pace, should not need you to drag a dial mid-bar. TRUE BACKGROUND MIXING The click mixes with whatever else is playing, and keeps going with the screen off and the app in the background — ninety minutes and beyond, uninterrupted. LOCK SCREEN CONTROL Start, stop and change tempo from the Lock Screen and the Dynamic Island. Your hands stay on the instrument, or keep moving. TAP TEMPO Tap out a few beats and Underbeat takes the tempo from you. BUILT FOR TIMING The beat grid is rendered ahead of time and played from a single buffer, so the interval between clicks does not drift over a long session. Every other feature depends on that. Underbeat has no accounts, no adverts and no analytics. It collects nothing and sends nothing anywhere.
