I love this product and the analysis it gives. But i think the app should more user friendly as in for users who cant really make a conclusion out of all this data. You should give a daily score basing on all of the analytics. A score that would give an intuative idea of how recovered are you and a value that will let you know how hard can you push it today. Further more, regarding sleep analysis, you should give advise on how much sleep we should get following a day. For example if i sync my device at night, i would get the analytics from throughout the day and the app can show me how much sleep i need to get to have more of a chance to wake up recovered. Other than that great product. Great analytics and the strap 2.0 never falls. Just need to twick the app a bit.
