Good experience
Been a month or more since app download and I still use it over my built in alarm. Wake up "is" not so abrupt and Im not sure how I feel about putting the phone near your head during sleep so the apps algorithms can audibly measure your cycle and gauge when best to trigger alarm sound, as it is bad to have a phone near your head. Even Dr. Oz says so! but I like the App yes!
