I think it needs several improvements. – Polar Flow Review

It works well with the clock in terms of synchronizing and pulling data from my clock. I also really like the GPS feature when I cycle. Having said that, the design feels like a spreadsheet. It give me the information I want without allowing me to expand and understand better. Also, I cannot zoom in my heart rate data to see the values in better detail. The same is true with my sleep data. Finally, I do not have access to my historic heart rate data apart from the work out sessions. Thank you!
