Thaw and Tell - read your cold-finger colour log

Log the times your fingers went pale, blue or red in the cold, one line each, and say when it began. The page tallies colours, minutes, fingers and settings on a hand picture and checks for warning signs, free. One metered run reads the pattern: the settings that set episodes off, what your own lines say helped, three gentle warm-up moves and, when the check calls for it, a note for a doctor; the page re-checks it. Not medical advice. Built on the SkillSafe skill @huifer/health-trend-analyzer.
