Understand the patterns behind your fatigue.

Even Keel looks back over the data your tracker has already gathered, finds the patterns in how you crash and recover, and turns them into plain English you can pace by. It pays the most attention to the way a crash can land a day or two after you have overdone it, the pattern that is hardest to catch by feel alone. I built it for my wife, who lives with CFS, after watching that data sit there unused.

Please take it as a way to spot patterns in your own past data, nothing more. It is not a diagnosis, and it is not a substitute for advice from a doctor.
