This is such a great development-I just has to make a post about it. I've had a form of insomnia for 8 years & this alarm has changed the 3 days of my life that I've had the Pro edition. I plug it in to my charger & put it on my night table or mattress next to me,keep the sensitivity setting at 50 & sleep. Even if I don't sleep that well atleast I get to see what times I move around & how much. I love it so much & I thank the administrators & developers for going this far to help people like me. 
