PS As for the reliability of awakening, I can not yet say much, except the few times I've tried the whole thing just now. But the reviews on the AppStore, according to the supposed will have no problem. So a round thing for a decent price with great options, successful design and a truly impressive sound quality for this small device size :)
Addendum: I now have now a number of different alarm clock apps tested and something goes horribly wrong here completely! Slowly I feel that the dock iPod somehow messes up ... Sometimes I am awakened as planned, but in just over 25% of cases, the alarm goes on though, it is but no sound ... The menu will appear and the alarm goes off, so to speak silently. Certainly not necessary to say that one of them is not monitored because any signal is missing .. I have repeatedly checked all settings, apps uninstalled and then reinstalled it, and even the iPod once reset to factory settings, all unsuccessfully. In absolutely incomprehensible distances of the alarm clock just goes on silently and not wake! This happens even now from time to time, when I use the iPod is not on the station point, completely arbitrary and whatever alarm clock app. These errors are previously never occurred until now in combination with the station ... This is very unsatisfactory, because I can not fix the error, and the station can not be used as an alarm clock, which was the original purpose of the purchase. Although the error now appears primarily to start from the iPod, but since this otherwise also works properly and the error apps or only in connection with the station clock occur, there must be a connection since ... Perhaps it is the ipod not it clear, to stand for many hours in the ward and to be permanently charged, but that's the intention, because it must not happen a mistake ...
