Tempi funktioniert nicht

It's like a reverse metronome. * diese App listens while you (or your entire band) play. * diese App reports the BPM (beats per minute) of your performance in real time with remarkable accuracy. * When you’re done, diese App 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. * Export the audio recording of your performance to keep or share with others.  Use it instead of a metronome while practicing to pinpoint problem areas in a piece of music that you’re learning. diese App 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.  diese App measures you and your entire band’s tempo live, while you play, and lets you analyze the performance when you’re done.  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. diese App is great for individual practice too.  When you’re done playing the song, press the stop button to analyze the performance.  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.  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.  With less structured music it still does quite well but may occasionally report incorrect tempos.
