July 2017: New: The Challenge Report, Better Insights

The new challenge report, displayed after completing a challenge, will tell you exactly how you've changed since your last challenge. See how much you've gone up or down, and get tips on what your scores mean.

Insights are now more representative of the population, and it is harder for a small number of people with uncommon data to influence results.

Entering your bed time and wake-up time is now much easier, thanks to a new time picker.
