Built by parents doing OIT with our daughter.

OIT Journal is a free iPhone app that helps parents keep a daily dose log during their child's oral immunotherapy (OIT) for a food allergy: each dose, the observation window after it, any symptoms, and a PDF report for the allergist.

One tap on a normal day

On a normal day, one tap logs today's dose with the time and starts the observation window. If the day is different, the other button lets you note what's going on, like a fever or poor sleep, or record a skipped dose with a reason.

The Today screen at 07:31, after one tap: Mara's peanut dose given at 07:31, the banner Dose logged, observation started with Undo, the observation window card Watching closely, ends at 09:31, and a Log a symptom button.

Now you watch.

The two hours after, on your lock screen

A Live Activity counts the observation window down where you will see it, with a short after-dose reminder. Tap Log symptoms to jump back to today's dose. When the window ends, you get a notification.

Two hours is the default. If your clinic watches longer or shorter, set your own length. Your clinic's instructions always come first.

An iPhone lock screen at 08:43 on Thursday, October 15, with the OIT Journal Live Activity for Mara: the observation window counting down with 47:51 left, its progress bar, a short after-dose reminder and a Log symptoms button.

Watch the progress add up

Every dose adds to the days on plan, and each new dose step climbs the ladder. Milestones mark the way, like 50 days on plan, and show the next one ahead. Each allergen keeps its own dose history.

The Progress tab scrolled to its charts: the dose ladder, the peanut protein so far and this week, a monthly chart of doses, and a typical dose time of about 07:30.

A clear report for your allergist

Pick a period and share one PDF: a summary, the dose chart, reactions and a day-by-day log.

Treated in St. Pölten? The app also exports the clinic's own paper dosing diary, in German. OIT Journal is independent and not affiliated with or endorsed by the clinic.

The Export screen: Whole OIT selected as the period, 19 Aug to 15 Oct 2026, 58 days, report language English, Include notes on, a preview of page 1 of 4 and the Create and share PDF button.

Every child, one tap each

Siblings in OIT? Each child gets their own allergens, doses and observation window. When both are in their window, the app asks who a symptom is for.

Mara and Leo's day at 07:40, both children in their observation window, with a sheet asking Who is this for? that lists Mara, in the window until 09:31, and Leo, in the window until 09:40.
The OIT Journal Today screen at 07:30: Mara's peanut dose, not given yet, with the question How's Mara feeling today?, a Feeling good, give dose button and Something's off today.

Both parents, one diary

Invite your partner with an 8-character code. Whatever either of you logs shows up on both phones, so you both know if today's dose is done.

Private, and it works offline

Everything is saved on your phone first and syncs when there is signal. No ads, no tracking, and your data is never sold. Delete your account any time, right in the app.

Questions parents ask

Is OIT Journal free?

Yes. OIT Journal is free on the App Store for iPhone, with no ads and no tracking.

Does OIT Journal tell me what dose to give?

No. OIT Journal is a diary. You enter the dose your allergist prescribed and update it when they change it, and the app records what was given. It never suggests or changes a dose. Always follow your allergist's plan.

Does OIT Journal watch my child or detect reactions?

No. OIT Journal is a diary and a timer. It counts down the observation window and tells you when it ends, but it cannot see your child or recognise a reaction. Watch your child the way your clinic told you to. If you think it is anaphylaxis, follow your emergency action plan: use the adrenaline (epinephrine) auto-injector as prescribed and call your local emergency number.

Which allergens can I track in OIT Journal?

OIT Journal has peanut, cashew, walnut, hazelnut, almond, pistachio, milk, egg, wheat, soy, sesame, fish and shellfish built in, plus any allergen you add by name. A child can be on several at once, each with its own dose.

Can both parents use OIT Journal?

Yes. One parent creates an invite code in OIT Journal's Settings and the other joins with it. You then share one household diary on two phones. Anyone else who helps with care can join the same way.

Does OIT Journal work without internet?

Yes. Logging doses and symptoms and the observation window all work offline in OIT Journal. The app syncs with the other phone once you are back online.

Is there an Android app?

OIT Journal for Android is on its way. Join the waitlist below and we'll email you when it's on Google Play, and about nothing else.
