I have had problem to log in because of a bug and when I contacted emphatek, one person from it answered quickly and have been very patient in order to solve my problem. The app is convenient, but the function "wake or sleep" not really. It would be better if it could be set up like an alarm clock (where you can choose when you want to wake up) rather than like a time-switch. Also it would be really convenient if this wake timer could work while the app in the background and the screen locked. I would appreciate that the message from the empty wish list and favorites to stop popping up every time I touch them, once is enough.
