The Study and Coach function is free for all healthcare professionals that want a easy way to follow their clients progress using a ketogenic diet.
A doctor, nutritionist could with one click create their own "study". The "study" is a group of clients that one wants to access their logged breath acetone and other data points like nutrients and exercise.
It works like this:
First the doctor/dietitian/nutritionist/coach selects Create Study, then choose a name which identifies the group of clients who is targeted.
The result is a pair of keys, one is the Study Id the other is a Study Key. There is also a third key generated, the Resign Key. The Resign Key is only available to the clients on request to stop participating in the study.
