FlareCast

If your fitness tracker treats a bad day like you're broken, you're using the wrong app.

FlareCast is built for people living with autoimmune and chronic illness (Sjögren's, lupus, RA, MS, fibromyalgia, and more), by someone who lives it too. Instead of a fixed step goal that ignores how you actually feel, FlareCast gives you one honest number: your capacity %, calculated from your sleep, symptoms, fever, stress, and check-ins. A 30% day is a 30% day. FlareCast tells you that, and tells you why, so you can pace yourself instead of pushing through and crashing.

See the pattern. Protect your pace.

Track what matters: symptoms on simple sliders (customizable to you), body temperature with a fever flag, hydration, stress, mood, notes with photos, medications with reminders, and your cycle if you want it.

Works with the wearables you already wear: FlareCast reads from Health Connect, so your sleep, heart rate, HRV, and activity flow in from your Galaxy Watch, Oura or Galaxy Ring, Fitbit, Pixel Watch, Garmin, Whoop, and more. No new device to buy.

One tap, a doctor-ready report: generate a clean PDF of your last 30 days to email your specialist, so you walk in with the whole picture instead of a foggy memory.

Your data stays yours: everything lives on your phone. No account, no cloud, nothing sold. FlareCast augments your health apps, it does not replace them.

FlareCast is free to use, with an optional Premium subscription for the deeper analysis layer (long-range trends, forecasts, the visual body-map report, and more).

FlareCast is not a medical device. Anything it shows is for personal pattern tracking, not diagnosis or medical decisions. Always talk to your doctor.
