Frequently asked questions

Yes. The everyday loop is always free: logging foods with a yummy or yucky verdict, tracking allergens with the watch window, and recording feeds, sleep, and diapers. Plus is an optional subscription that adds unlimited babies and caretakers, video clips, the Journey keepsake, and diaper and formula price tracking.

You do not have to. YummyYucky is on the App Store for iPhone and on Google Play for Android. You can also install it straight from your browser on any device (iPhone, Android, or desktop): it adds to your home screen in a couple of taps and behaves like a normal app. However you get it, it is the same YummyYucky.

Yes. You can log a bite with no connection and it saves on your device, then syncs automatically once you are back online. Handy in the baby-aisle dead zone or a basement nap room.

No. YummyYucky is funded by parents, not their data. Your baby’s logs, photos, and reactions belong to you, and we don’t sell them.

Yes. You can share a baby with other caretakers so everyone logs to the same record. Whoever feeds the baby can log it, and it all shows up in one place.

Yes. You can add more than one and switch between them. The free plan covers one birth, and multiples count as one, so twins or triplets are free as long as each birthday is within 30 days of the first sibling you add. A separate birth, or a baby with no birthday to check, is where Plus comes in, which also raises the caretaker limit and unlocks video.

Yes. Parents around the world use it, and the feeding guidance is general and drawn from sources like the AAP, CDC, and NHS. Plus diaper price tracking now works in the US, UK, Canada, Australia, New Zealand, Germany, and France, showing prices in your local currency from local stores.

When you introduce a common allergen, offer it on its own and keep an eye out for a reaction over about 3 days (most reactions are quick, but a few are delayed). Introduce one new allergen at a time and let its window close before starting the next brand-new one, so any reaction can be traced to a specific food. If two allergens are being watched at once and a reaction shows up, it is much harder to tell which one was responsible. YummyYucky opens an observation window on each new allergen, tells you when it is clear to start the next, and reminds you to keep the ones that go fine in regular rotation. The one thing not to do is put off introducing allergens; early and steady is the goal.

Foods (with a yummy or yucky verdict and optional photo or video), allergen introductions, bottle and nursing feeds, sleep, and diapers. There is also a food library, feeding, sleep, and diaper trends, and evidence-informed guides.

No. It is a tracker and a source of general, evidence-informed information, not a substitute for your pediatrician. Always talk to your doctor about your baby’s diet, introducing allergens, and any reaction. In an emergency, contact emergency services.

Yes. The iPhone app is on the App Store and the Android app is on Google Play. You can also install it straight from your browser on iPhone, Android, or desktop, where it adds to the home screen like a normal app.

Both, from Settings inside the app. You can download a copy of your data whenever you like, and you can delete your account and everything in it just as easily. Your data is yours.

Please do. There is a feedback form linked in the app and in the footer, and a real person reads every note.
