BPM Detector: Live Tempo is a free multimedia app available for iPhone users. Developed by Quentin Hayot, this app automatically detects the tempo of music using your device's microphone.

With BPM Detector, there is no need to manually tap to find the tempo. The app intelligently analyzes the sound captured by the microphone and accurately determines the BPM (beats per minute) of the music. This makes it a convenient tool for musicians, DJs, and anyone who wants to know the tempo of a song.

One of the standout features of BPM Detector is its integration with Shazam. For iOS 15 and above, the app seamlessly integrates with Shazam to provide not only the tempo but also the track's name and artist. This enhances the user experience and makes it easier to identify and categorize the music being detected.

Another useful feature is the detection history list. This feature, available for iOS 15 and above, allows users to keep track of their detections over time. The list includes the Shazam track IDs and BPM for each detection, providing a comprehensive record for reference.

BPM Detector also offers a fullscreen mode, which displays a large BPM counter. This makes it easy to view the tempo from across the room, ideal for situations where the app is being used in a live performance or for monitoring tempo during rehearsals.

Overall, BPM Detector: Live Tempo is a reliable and user-friendly app for automatically detecting the tempo of music. Its integration with Shazam and the detection history list add value to the app, making it a versatile tool for musicians and music enthusiasts alike.
