Health Flare

Chronic Illness Companion

Health Flare is a private, offline-first health companion designed for people living with chronic illness.

Track your health story — symptoms, vitals, medications, meals, sleep, flares, activity, and daily check-ins — all in one place, all on your device. There are no accounts, no servers, and no cloud. Your data never leaves your phone unless you choose to export it.

WHAT YOU CAN TRACK

• Symptoms — log severity over time to surface patterns • Vitals — blood pressure, heart rate, temperature, oxygen, weight, blood glucose • Medications & doses — track what you take and when • Meals — note what you eat and flag reactions • Sleep — bedtime, wake time, quality, and naps • Flares — document flare start, severity, and triggers • Daily check-ins — wellbeing, stress, and optional cycle tracking • Activity & rest — log exertion with a PEM (post-exertional malaise) flag for ME/CFS • Doctor visits — keep a record of appointments and notes • Journal — long-form entries with mood and energy tagging

BUILT FOR CHRONIC ILLNESS

Health Flare was designed with the chronic illness community in mind, not the casual wellness market. It supports the kinds of tracking that matter for conditions like ME/CFS, fibromyalgia, lupus, EDS, POTS, IBD, MS, and other complex long-term conditions — including a dedicated PEM flag for post-exertional activity logging.

MULTI-PROFILE SUPPORT

Manage health records for yourself and the people you care for. Add profiles for family members, switch between them in seconds, and keep each person's data completely separate.

YOUR DATA STAYS WITH YOU • No account or login required — ever • No data uploaded to any server • No analytics, telemetry, or crash reporting • No advertising • Data stored in a private, sandboxed database on your device • Optional backup lets you export your data as a file and store it wherever you choose

Health Flare is not a medical device and does not provide medical advice. Always consult your healthcare team for medical decisions.
