OIT Journal
Read full descriptionHide full description
OIT Journal is the daily diary for families going through oral immunotherapy (OIT) for food allergies. Log each child's dose in one tap, keep the observation window in sight, watch the progress add up, and bring your allergist one clear report. ONE TAP ON A NORMAL DAY Feeling good? One tap logs the dose and starts the observation window. Something off, or skipping a dose? Note what happened and 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, with no need to keep the app open. What to avoid (no strenuous activity, no hot bath) stays visible the whole time. EVERY CHILD, EVERY ALLERGEN More than one child in OIT? Each child gets their own allergens and doses, and you switch between them in a tap. Every allergen keeps its own dose, history and up-dosing steps, in mg protein or the unit your clinic uses. Doses stay editable as your clinic adjusts the plan. WATCH THE PROGRESS ADD UP The Progress tab shows each allergen's dose ladder, the milestones you've reached, the amount so far and how many doses went calmly, month by month. The calendar shows every day at a glance: given, skipped, symptoms and step-ups. SYMPTOMS THE WAY YOUR CLINIC RECORDS THEM Log symptoms with a dose or on their own, using the severity scale of the daily protocol sheet. When two children are in the observation window, the app asks who it's for. A CLEAR REPORT FOR YOUR ALLERGIST Pick a period and share one PDF, the OIT Journal report: a summary, the dose chart, reactions and a daily log with your notes. If your clinic uses the German-language paper dosing diary, you can export that form too, one page per month. ONE HOUSEHOLD, ONE RECORD Both parents log from their own phones and always see the same diary. Invite family members with a short code, and everyone stays in sync automatically. 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; entries sync when you're back online • Optional Face ID / Touch ID lock • In English, German, Romanian and Spanish • 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.

Verdict
The clearest difference is in-app purchases: OIT Journal at none against Tolerance Tracker 2's 10. OIT Journal also leads on update cadence (every 2 weeks vs monthly). On price, ads, device support and iOS requirement there is nothing between them.
