Emberlog is the symptom tracker for chronic illness flares, doubling as an endometriosis tracker and POTS tracker for the conditions that need close pattern-watching. When you live with IBD, CFS, POTS, fibromyalgia, or endometriosis, patterns matter. This flare diary helps you catch them without wearing you out. - Log a flare in seconds: a time, a severity, and whatever details you have energy for - Note the factors that might play a role, like sleep, meds, food, and mood - See gentle pattern cards with honest sample sizes, computed right on your phone - Pull sleep and activity from Apple Health instead of typing them twice - Bring a clean, date-ranged summary to your next appointment Your entries stay on your device. Emberlog is a personal journal, not medical advice. It does not diagnose or treat any condition; discuss patterns with your clinician.
