Great iPhone app, Apple Watch app almost there...
This app is amazing for monitoring heart rate throughout the day and really being to analyze it. From using this app I really can identify patterns that have lead to lifestyle changes and Im so glad I downloaded it. Having said this, there is improvement that can be done for the Apple Watch app. It is a very fast app for the watch, however the complication for the watch face does not update enough and that makes it not as useful to glance at. Fix that and this should be a "must have" for all Apple Watch users!
