Tempo: Live BPM & Takes

Tempo shows the tempo of live music as you play, records takes and shows how the tempo moved over time. It was made for a brass band and works for any band, orchestra, choir or player who wants to know: are we rushing, dragging, or right on the beat?

LIVE TEMPO
• Tap Listen and play: after about 5 seconds the tempo appears in BPM.
• A white number is a sure reading; a grey one is the last good reading while the music is unclear.
• Counting in halves or doubles? Tap ½ or 2× and the app stays at that level. Hold to pick ⅓ or 3× for music felt in 2, like 6/8.
• Time signature (3/4 or 4/4) with one dot per beat, the first beat of the bar larger.
• While the tempo moves, an arrow shows whether it is going up or down.
• Analysis window of 4, 6, 8 or 16 seconds: shorter follows changes faster, longer is steadier.
• Tap tempo when there is nothing to listen to.

RECORD TAKES
• Tap Rec, play, tap Stop. Optional count-in clicks and a fixed length with a progress ring.
• Every take shows its tempo curve: average, range, drift per minute and steadiness.
• Hold a finger on the graph to read the tempo at any moment.
• Play the recording back with a dot bouncing on the beats.
• Rename takes and keep them in folders with colours and symbols, inside each other if you like.
• Compare two to four takes of the same piece, by time or by percentage of the take.

KEEPS GOING IN THE BACKGROUND
• Switch apps or lock the screen: the tempo stays in a notification, with Slower, Faster and Stop.
• A take being recorded goes on in the background until you stop it or its length is reached, even if you close the app.
• On Android 16 the tempo can appear as a Live Update in the status bar, where the phone supports it.
• Both can be turned off in Settings.

SHARE AND KEEP
• Share the audio of a take as M4A, WAV or the original recording.
• Export the tempo readings as a CSV file for a spreadsheet.
• Import any audio file and see its tempo curve.
• Back up all takes and folders to one file, for example on Google Drive, and restore them on another phone.

PRIVATE BY DESIGN
• Audio is analysed on your phone. Tempo has no account, no ads and no tracking, and its code makes no internet requests.
• Takes stay on your phone until you share them or make a backup.

ALSO
• Light, dark or system theme, portrait and landscape.
• A short guide to every function in About.
