Good but as some people already pointed out it reconnects on its own , does not disconnect sometimes and does not connect sometimes. These issues can be dealt by force stopping the app but should be fixed by the developer. Anyway does the job most of the time Muito bom!
I would give 5* BUT, when internet is active with the alarm set, the alarm starts on its own without anyone messing with the phone after a while, without internet access it works just fine. Also, in the next version I would recommend to add some selfie option and send that photo via email and gps coordinates in case phone got stolen while the alarm is on. Thanks Perfect
