MagicBPM vs MetroGnome

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.

MetroGnome is an iPhone and iPad app combining a metronome, rhythm-pattern editor, and instrument tuner. Its metronome runs from 20 to 300 BPM and offers tap tempo, customizable meters, subdivisions, nine synthesized tick sounds, and live beat accents ranging from strong to silent. Eleven flamenco palos include traditional accent cycles that can be edited during playback. The pattern editor supports unlimited measures, mixed time signatures, rests, tuplets, repeats, tempo changes, and real staff notation. The tuner covers 60 instrument tunings across five families, plus chromatic Any Note mode and 16 historical reference pitches such as Baroque A=415 and Verdi's A=432. These tools run on-device and offline without an account or login, while clicks continue with the screen locked or another app open. The maker says tuner audio is analyzed in memory and not recorded, stored, or transmitted. iOS 17 or later is required; Android is coming soon.
