Check how well you sleep! And identifiy your rest HR! How to identify your rest HR? Well, with this APP it is easy - have a sleep with your belt and in the morning you will have all the data in your Ambit - just transfer it to Movescount and check your charts. Just before a sleep or right after you will see on your Ambit the approximation of your RestHR so far - and you don't have to sleep with the watch - just place it close to your bed. 1) Save this APP 2) Add it to one of your sport modes 3) Enable logging of data - you will be able to see a chart for SLEEP MONITOR - REST HR IDENTIFICATION 4) I configured just two screens for "SleepWell" sport mode: the first with: HR Rate, this APP, and Calories; the second screen with a graph for HR Rate 5) After a sleep it is fun to analyze your HR graphs and "restHR" graph - you can easily identify your rest rate and adjust it manualy in your Ambit (it is not like with SUUNTO_USER_MAX_HR, which is being adjusted automaticaly!) Enjoy!
