Description
Built by someone who spent months tracking his own condition in a spreadsheet because nothing else felt right.
If you've been dismissed, doubted, or told to wait it out, this app is your evidence. A quiet, structured way to document your symptoms and walk into your next appointment with real data instead of a half-remembered list.
Flare works for back pain, arthritis, fibromyalgia, migraine, endometriosis, pelvic pain, sciatica, nerve pain -- and any condition you want to track. Start from a template for your condition, or build your own.
