This is the app to the new book "Nachtwandler" from Sebastian Fitzek.
What exactly does "Nachtwandler"?
Nachtwandler is started at bedtime and then waits for the noise level that you preset to be exceeded. When this happens, the app starts recording for the period of time that you specified. The next morning, you can then listen to the noises you made. You can name your session (e.g. nose clip was used, alcohol was consumed) even before the recording starts and immediately determine whether this measure resulted in any sort of change during sleep. You can move the best recordings into the "Hall of Fame" or share them with friends.
Have a lot of fun and success with Nachtwandler.
