Best app for Apple watch – Heart Analyzer: Cardio Monitor Review

This is the single best app for Apple watch and surprising Apple hasn't included this functionality natively like Fitbit and other teachers. This app Bridges the gap with other fitness trackers and while not 100% accurate is really darn close and extremely useful. Thanks so much! Also the developer is fantastic at responding to emails!
