Ive only been using the app for since the weekend, but so far its okay. The mode beta/activity does seem to help me focus a little better at work. The alpha/relaxation is an awesome lil tool as well because once youre ready to lay down or even just to relax and watch TV, it sure does help to relax you... Cant wait to see how its working in 6 months from now!!
