Getting better

This app is fairly good, I really would like to access all my metric data either through the app or have their website support a mobile browser. The website has great breakdowns of all the metrics that are recorded, it would be wonderful if they could add those features to mobile. It's nifty now, but will be amazing when they do that. Also they should add a way to force the watch to read a HR, sometimes it'll go 5 mins without reading a HR, it's annoying to see the graph have 50 data points in 50mins when your heart rate barely varies, then when you're active and heart rate is varying and rising, the watch seems to suddenly not take a reading for an inordinate amount of time. It's not even that it is having trouble, it is that it is not even trying. I've gotten good readings above 100bpm, but when my rate is over that, the interval reading is 5-10mins apart vs when I'm resting and the interval is as little as a few seconds for a real time reading. Love the watch, the app is getting there, the firmware would be nicer if customers were allowed more control of the metrics displayed and allowing for a forced reading of the HR or at least an error message stating it is having trouble rather than showing data that is obviously not true like when I ran a mile and the watch was stuck saying my bpm was only 55. Great potential so close to being unleashed.

Great health tracking app, bugs fixed

Great app. Most detailed sleep analysis of any health tracker (and I've tried several), and very glad that this is focused on establishing and tracking goals rather than just plainly reporting activity metrics. Best app & device on the market and highly recommend them.

Great Tracker!

I love the detailed information that the Basis and provides, especially the in depth sleep analysis. The only reason I am rating this device four stars out of five is that I wish the band would automatically sync with my iPhone. The manual sync is a pain. Perhaps newer updates will have this capability.
