Immunally helps you understand your autoimmune condition by turning everyday logs into clear, personal insight. Living with lupus, RA, ITP, thyroid disease, or another autoimmune condition means noticing what your body is telling you — and remembering it when it matters. Immunally makes that effortless. Log symptoms, meals, medications, and labs in seconds by voice, photo, or tap, and let the app surface the patterns you can't see day to day. WHAT YOU CAN DO • Log fast — speak it, snap a photo of a meal or lab report, or tap. No long forms. • Track symptoms and flares — severity, timing, and how you actually felt. • Connect Apple Health — bring in sleep, steps, heart rate, and more automatically. • Log medications — doses, changes, and adherence over time. • Add lab results — snap a photo and Immunally reads the values, then charts your trends. UNDERSTAND YOUR PATTERNS • Daily briefs that connect the dots between sleep, activity, diet, and how you feel. • Weekly and monthly reviews that summarize what changed and why it might matter. • Trigger detection — see which foods, habits, or factors tend to show up before a flare. • Experiments — run a simple elimination test (like cutting dairy) and get a clear result. WALK INTO APPOINTMENTS PREPARED • Doctor prep turns your data into focused questions worth asking. • Share a clean summary or export for your care team. PRIVATE BY DESIGN • Your health data is encrypted. • We never sell your data or use it for advertising. • You're always in control of what you track and share. Immunally is a tracking and insight tool, not a medical device. It does not diagnose, treat, or provide medical advice. Always consult your physician before making any change to your care. Made for people managing chronic autoimmune conditions who want to feel more in control — one log at a time.
