iPhone

Log every reaction, spot the trigger, and hand your allergist a clean PDF history. Private, on your iPhone — built for food allergy families. Every allergic reaction leaves a clue. Allergy Tracker turns those scattered clues — what you were exposed to, how bad it got, how long it lasted — into a clear history you and your allergist can actually work with. Purchase required: Allergy Tracker requires a paid subscription (weekly or yearly) or a one-time lifetime purchase to use. This is not a pollen forecast or a barcode scanner. It is a serious reaction logbook built for one job: capturing each reaction accurately in under a minute, then showing you which triggers keep coming back. It never tells you a food is "safe" — a missing entry is absence of data, not evidence — and it never invents treatment advice. It gives you the record; your allergist gives you the answers. WHAT YOU GET • Log a reaction in under a minute — trigger, severity 1–10, symptoms, body zone, duration and the treatment you noted • Walk into every appointment with a paginated doctor-report PDF instead of "it was maybe two weeks ago?" • See which triggers actually recur: allergen breakdown with average severity, symptom frequency and severity-trend charts • Separate profiles for each family member, so your child's milk-protein history never mixes with your hay fever entries • Blood type, known allergens, emergency contact and insurance details on one Emergency Info screen — findable in seconds • A daily reminder at the hour you choose, so the log stays complete enough to be worth showing a doctor PERFECT FOR • Parents managing a child's food allergy who need a clean timeline for the pediatric allergist • Newly diagnosed adults narrowing down which of five suspect foods is the real trigger • Anyone living with anaphylaxis risk who wants known allergens and emergency contacts kept in one place • People working through an elimination diet or suspected histamine or food intolerance who need dates, exposures and symptoms side by side WHY NOT JUST USE A NOTES APP? A note can hold a sentence; it cannot tell you that shellfish appears in six of your last eight severe entries, chart your severity over three months, or format itself into a report your allergist can read in ninety seconds. Structured entries are what turn "I think it's worse lately" into evidence. PRIVATE BY DEFAULT Your medical history stays on your iPhone. No account, no cloud, no analytics on your entries — the doctor report is generated on your device and shared only when you choose to share it. Allergy Tracker is a personal logbook, not medical advice: for severe reactions, always follow your prescribed anaphylaxis action plan and call emergency services. FULL ACCESS Allergy Tracker requires a purchase to use. Every feature — reaction logging, family profiles, Emergency Info, reminders, insights and the doctor-report PDF export — is available only with a paid weekly or yearly subscription or a one-time lifetime purchase. There is no free tier. Log your first reaction today — the pattern is already in your history. Give your allergist the data to find it.
