Fibromyalgia: questions people ask
How does Feelcaster learn my pattern?
Check in or log how you feel, especially on hard days. Each log keeps the weather from the hours before it, and the Report tab shows what your bad days have in common.
How much warning will I get?
A Feelcast Warning means a rough stretch is likely within the next 12 hours. A Feelcast Watch means one is possible within the next 2 days. Quiet hours, 10 PM to 7 AM, hold both back.
