No, i dont need it on all night. And besides i have a xiaomi phone that is turned off and sound the alarm, dont need a stand alone clock....thats why im intrigued....why the supposed best movil phones have to be ON so the alarm sounds. For me doesn't make any sense when other phones have been doing it for years.... only if apple is vey interested in hearing what you have to say at night....lol
About being harmless or not. I really don't trust the what they release as safe, like in US has safety values different from the EU. That makes me think. And i don't trust the FDA( allows poison in food, vaccines, etc), as the WHO, same, same. Also they say towers of powers lines are non-ionising, but its been proven that people that live under or near tower power lines, got leukaemia and other kinds of cancer...but hey, its just me wondering..
