App: Tempi – Live Beat Detection
Developer: Made by Windmill, LLC
Genres: Music, Education

Tempi measures you and your entire band’s tempo live, while you play, and lets you analyze the performance when you’re done. It's like a reverse metronome.

* Tempi listens while you (or your entire band) play.
* Tempi reports the BPM (beats per minute) of your performance in real time with remarkable accuracy.
* When you’re done, Tempi lets you analyze the recording so that problem areas can be pinpointed and improved.
* Use Tap for Tempo to quickly get a BPM reading at any time.
* Switch themes for easy nighttime use or just to suit your style.
* Recording sessions can be saved for later analysis.
* Export the audio recording of your performance to keep or share with others.

HOW TO USE

In a band setting, place the iPhone or iPad in a position where the entire band can see it so everyone will know when the band is speeding up or slowing down. When you’re done playing the song, press the stop button to analyze the performance. You can scroll through the entire song, isolate where the tempo sped up or slowed down, and play back the song to get an idea of what went wrong.

Tempi is great for individual practice too. Use it instead of a metronome while practicing to pinpoint problem areas in a piece of music that you’re learning. If you can play through an entire song with the tempo only changing by 1 or 2 BPMs, you’ve arrived :-)

Tempi works best when there’s a distinct “pulse” to the song, like a kick drum/snare or a repeating chord, and assumes the player is trying to play at a consistent tempo. With less structured music it still does quite well but may occasionally report incorrect tempos.

If your song is very fast or very slow, tap the button at the top right to toggle between 1/2x, 1x, and 2x tempos.

Release notes:
- Recording sessions can now be saved for later analysis
- The "range" button has been replaced by a button that toggles between 1/2x, 1x, and 2x tempos
