In their own words
MagicBPM
MagicBPM listens through a microphone to measure music tempo in real time, with a metronome and song identification. Its BPM readout updates as music plays and shows a confidence indicator as the reading settles; a scrolling tempogram displays tempo changes over time. The metronome supports up to 300 BPM, eight time signatures, accented downbeats, and eighth-note, triplet and sixteenth-note subdivisions. It can listen while music plays aloud from services including Spotify, Apple Music, YouTube and Deezer. Tempo analysis runs on-device, and microphone audio is not recorded or uploaded. Song identification sends an acoustic fingerprint to Apple’s Shazam service, requires internet access, and is disabled on CarPlay and Bluetooth hands-free routes. The app does not import audio files: users measure microphone-captured sound or tap the beat. Apps are listed for Mac, iPhone, iPad and Android, with an Apple Watch metronome. The core app is free; iPhone and Android versions show ads, while the Mac app is ad-free.
