HealthFace for Apple Watch

SPSS 

HealthFace goes deep on exposing health information as a complication on any Apple Watch face. Any data from HealthKit can be shown, and it’s easy to configure it to show different data on different watch faces — you can, say, show your sleep data on the Utility face and your blood pressure on Utility. The interface for configuring the complications is better than Apple’s.

If you have any interest in displaying your HealthKit data on your Apple Watch, HealthFace is the app for you. And it’s a great deal — a one-time purchase of just $1.99.
