Know What Your Baby Can Handle.

LittleClues is a food-allergy and symptom tracker for parents of babies and toddlers. You log what you and your little one eat and how they feel, and the app surfaces which foods are most likely behind their reactions.

Yes. All logging, photos and notes on symptoms, meal reminders, backup and restore, up to 5 safe foods per child, and a preview of the insights are free. LittleClues Pro is available for parents who want the full analysis — $4.99 per month or $39.99 per year, with a 30-day free trial on the annual plan. Those are US storefront prices; the app always shows your own local price.

LittleClues is available on iOS (including iPad) and Android. The app interface is in English. The built-in list of suggested food and symptom names comes in 10 languages — English, Spanish, Portuguese (Brazil), French, German, Italian, Polish, Lithuanian, Japanese and Simplified Chinese — and you can always type whatever you want.

It compares how often symptoms follow each food against how often symptoms happen anyway, during ordinary food-free stretches of your own log. Each food lands on a five-point chance scale — Very Low, Low, Moderate, High or Very High — or Needs more data if it has not been eaten on enough separate occasions yet. These are patterns to discuss with a doctor, not a diagnosis.

Because the reaction rate and the rating answer different questions. A food could show a high percentage under a calm label, or the reverse, and no reader could reconcile the two. Instead LittleClues shows the raw counts from your log — how many occasions were followed by a symptom and how many were not — next to the same counts for ordinary food-free stretches.

Foods you already know agree with your child. Mark one safe and it steps out of Foods to watch, so the ranking stays about the foods you are genuinely trying to work out. Nothing is deleted and the rating never changes — and if the pattern later disagrees with you, the app flags it as worth another look. Free for up to 5 foods per child; unlimited with Pro.

Yes, and it is free. Photos attach to a symptom — a rash, hives, a swollen lip — from the camera or your photo library, so the picture stays tied to that symptom and the time it happened. They are stored on your device, never uploaded, and you can choose which ones go into the PDF report for your doctor.

Yes. You can analyse a single symptom — just the rash, say — and it gets its own reaction counts and its own baseline, fully isolated. Picking one symptom never distorts the reading on the others. There is also an Any symptom overview that pools them together.

Yes. Food your baby ate directly and food that reached them through breast milk are tracked separately and scored on their own timescales, since those reactions show up differently.

LittleClues is local-first: your entries, foods, photos, profiles and settings stay on your device. There are no accounts and no server holds a copy of your log. Crash reporting and anonymous usage analytics are optional and can be turned off anytime.

No. These insights are based only on patterns in your own log. They are not medical advice — always check with a healthcare professional about suspected allergies.

Yes. You can add as many children as you need, each with their own name, color and breastfeeding setting, and keep a separate log for every one of them.

Yes. You can turn on optional breakfast, lunch and dinner notifications at times you choose, so logging becomes a habit.

Yes. You can export a backup to Files, iCloud or Google Drive and restore it later — photos travel with the data, and older backups always restore cleanly into newer versions. A doctor-shareable PDF report is included in LittleClues Pro.
