Even Keel

Understand the patterns behind your fatigue.

Even Keel reads the data your fitness tracker already collects and turns it into plain English. It is built for chronic fatigue, suspected ME/CFS, and fatigue during illness or recovery. It looks for the things that matter for tiredness, above all the way a crash can arrive a day or two after you have overdone it.

Your file is read inside your own browser and is never uploaded anywhere. If you add the optional AI guide, only a short, anonymous summary of numbers is sent, never your raw data.

A one-off download. You only need the daily summary file, and it is usually a couple of taps.
