About

OIT Journal

Features
Read full description

OIT Journal is the daily companion for families going through oral immunotherapy (OIT) for food allergies. Log the dose in two taps, keep the post-dose observation window in sight, and share one up-to-date record with everyone who cares for your child. TWO TAPS ON A NORMAL DAY Dose given, taken with food, "no symptoms" — captured in seconds. Skipped a dose? The app asks why, so the record stays honest and complete. THE OBSERVATION WINDOW, ALWAYS IN SIGHT After every dose, a Live Activity counts down the observation window on your lock screen and in the Dynamic Island — no need to keep the app open. Gentle reminders of what to avoid (no strenuous activity, no hot bath) stay visible the whole time. EVERY ALLERGEN, TRACKED ITS OWN WAY Single-allergen or multi-allergen OIT — each allergen keeps its own dose, its own history, and its own record of up-dosing steps. Doses are fully editable as your clinic adjusts the protocol. SYMPTOMS THE WAY YOUR CLINIC RECORDS THEM Log symptoms against a dose or on their own, with severity levels that match the daily protocol sheet — including the fast "no symptoms" path for the good days. ONE HOUSEHOLD, ONE RECORD Both parents log from their own phones and always see the same diary. Invite family members with a simple link — everyone stays in sync automatically. READY FOR THE CLINIC Export a clean, printable day-protocol PDF (in the format of the German-language daily protocol sheet) for your follow-up visits. REFERENCE AT HAND Keep your clinic's reaction flowchart and emergency action plan one tap away, along with your emergency contacts. ALSO INCLUDED • Daily dose reminder at the time you choose • Works fully offline — logs sync when you're back online • Optional Face ID lock • Calendar view of your full dosing history • In English, German and Romanian • No ads. Your child's data belongs to your household and is never sold. IMPORTANT OIT Journal is a diary, not a medical device. It does not give medical advice, does not recommend doses, and is not a substitute for your allergist. Always follow your clinic's protocol — and in an emergency, follow your action plan and call emergency services.
