Nibble Book

1. Tap a food

There are 100 foods to discover, sorted into Veggies, Fruits, Proteins, Grains, and Allergens. Foods your baby hasn't tried yet are pencil sketches.

2. Log how it went

Choose the date and a reaction (Loved it, Liked, Disliked, or Allergy), add any notes, and tap Save. The food fills in with color.

3. Watch when it's a new allergen

When you log an allergen today, choose a time and tap Save & Start Watching. A countdown appears on your Lock Screen. When time is up, or when you tap the ... button and choose Finish Now, the app asks if you noticed any reaction. Answer, and the food fills in with color.

4. Share the list

Tap Export List and type your baby's name. Your list becomes a single image, with any reactions at the top. A ✓ marks foods you watched for the time shown without noticing a reaction. Save it to Photos or share it with your pediatrician or sitter.

Why are some foods already filled in?

The first time you open the app, 12 example foods show how the journal looks. Tap Start Fresh to clear them. Examples never appear in a list you save or share. If you open an example and tap Save, it becomes part of your own list.

Why can't I save or share my list yet?

Your list needs at least one food of your own. Until then, the preview uses the examples and is marked SAMPLE.

How long should I watch?

That's for you and your pediatrician to decide. You can pick 1, 2, or 4 hours. A finished watch doesn't mean a food is safe, and reactions can also appear later. If you notice one later, tap the food and change its reaction to Allergy.

The countdown isn't on my Lock Screen

Check Settings › Nibble Book › Live Activities. The countdown also shows at the top of the app. If you turned off notifications, the question appears in the app when you open it.

How do I remove a food?

Tap the food, then tap Remove from List.

Save to Photos doesn't work

iOS asks for permission the first time. If you said no, turn it on in Settings › Privacy & Security › Photos › Nibble Book.

Is my list backed up?

It's stored in the app on your iPhone and is included in your iPhone backup. It doesn't sync between devices, and deleting the app deletes it. To keep a copy, save your list to Photos.

Does the app tell me which foods are safe?

No. Nibble Book is a place to write down what your baby has tried. It doesn't give medical advice and isn't a medical record. Ask your pediatrician when and how to introduce foods, especially allergens. If your baby has trouble breathing, swelling of the lips or face, or repeated vomiting, call 911.

Nibble Book doesn't collect any data. The developer can't see your baby's name, foods, reactions, or notes. There is no account, no analytics, no advertising, and no tracking.

What's stored

The name you type and the foods, dates, reactions, and notes you log are stored in the app on your iPhone. Nothing is sent to a server.

Photos

If you choose Save to Photos, iOS asks for permission to add the image to your photo library. The app can't read your photos.

Notifications and Live Activities

If you allow them, the app schedules a reminder on your iPhone for when a watch ends and shows a countdown on your Lock Screen, including the food's name. No data is sent to a server.

Sharing

Your list leaves your iPhone only if you send it. Whatever app you share with handles it under its own policy. The image includes the name you typed and any notes on foods marked Allergy.

Deleting your data

Tap a food and choose Remove from List, or delete the app to remove everything.

Children

The app is meant for parents and caregivers. It doesn't collect information from anyone, including children.

Changes

If this policy changes, the new version will be posted on this page. Last updated November 7, 2026.
