MagicBPM

Overview

MagicBPM is a microphone-based tempo detector with a metronome and song identification, available across Apple and Android devices. It suits musicians who want to find the tempo of music playing aloud and then practice against a matching beat. Its strongest case is the combination of live BPM readings and flexible metronome controls; its main constraint is that it cannot analyze imported audio files.

The tempo readout updates as music plays and includes a confidence indicator for when a reading settles. A scrolling tempogram gives a view of tempo changes over time, which is more useful for music that shifts pace than a single BPM number alone. Users can also tap the beat to enter a tempo manually.

Tempo analysis runs on-device, and microphone audio is not recorded or uploaded. Song identification is separate: it requires internet access and sends an acoustic fingerprint to Apple’s Shazam service. Identification is disabled on CarPlay and Bluetooth hands-free routes. The free app uses Google AdMob; its privacy policy says it does not run its own servers or use analytics or crash-reporting tools.

Key features

• Live tempo detection: The changing BPM reading and confidence indicator help users distinguish a settled result from one still finding the beat.
• Metronome: It supports up to 300 BPM, eight time signatures, accented downbeats, and eighth-note, triplet, and sixteenth-note subdivisions. That range makes it useful for varied practice rhythms, though custom time signatures are not supported.
• Tempo visualization: The scrolling tempogram shows tempo changes over time, adding context when a piece does not hold one steady pace.
• Music services and identification: MagicBPM can listen while Spotify, Apple Music, YouTube, Deezer, and other services play aloud. Identified-song history can link to Apple Music, Spotify, YouTube Music, Amazon Music, Deezer, TIDAL, or SoundCloud.
• Audio input: It measures sound through the microphone or accepts a tapped beat, but does not import audio files. Anyone who needs to analyze a saved recording directly should choose another workflow.

Pricing

Free — free. The core app is free. The iPhone and Android apps show ads, while the Mac app is ad-free. This is the straightforward choice for tempo detection and metronome use without paying, but it does not include the Pro-only features.

MagicBPM Pro — custom pricing. It is a one-time purchase, with automatic song identification, song history, 12 additional metronome sounds, and ad removal on iPhone and Android. Pro is the fit for users who want identification and saved history or prefer an ad-free mobile app.

Platforms

MagicBPM supports macOS, iOS, Android, and web. Device support includes Mac, iPhone, iPad, Android phones, and an Apple Watch metronome. Minimum versions are macOS 15, iOS 18, iPadOS 18, watchOS 11, and Android 9, so older devices may not qualify. The listed platform coverage includes web, though watchOS is also supported for the metronome.

Who it's for

Choose MagicBPM if you want to identify the tempo of music playing aloud, use the result for practice, and have metronome subdivisions and accents in the same app. Its on-device tempo analysis is also a strong fit for people who do not want microphone audio uploaded. It is a poor fit for direct analysis of audio files, or for song identification when offline or listening through CarPlay or Bluetooth hands-free.

Developers can ask about a licensable SDK for on-device, offline tempo detection on iOS and Android. The maker says it is tuned for steady rhythmic material and that general-purpose libraries are stronger for broad multi-genre offline analysis, including jazz, classical, and solo acoustic music.

Pros and cons

• Pros: Live BPM readings include a confidence indicator, helping users judge when the result settles.
• Pros: The metronome combines a 300 BPM ceiling with eight time signatures and three subdivision types.
• Pros: Tempo analysis is on-device, with no microphone audio recording or upload.
• Pros: The core app is free, and Mac use is ad-free.
• Cons: Audio files cannot be imported, so the app cannot directly analyze a stored track.
• Cons: Song identification needs an internet connection and is disabled on CarPlay and Bluetooth hands-free routes.
• Cons: Custom time signatures are not supported.
