LittleClues: Allergy Tracker

Figuring out which food is upsetting your baby is genuinely hard. Foods get eaten together, symptoms arrive on a delay, and if you're breastfeeding, what you eat matters too. LittleClues is a food and symptom tracker built for parents of babies and toddlers. Log what you and your little one eats and how they feel — and let the app surface the patterns. Not guesswork. Actual data from your own log. LOG IN SECONDS - Log foods and symptoms as dated, timed entries - Track what the child ate directly — or what reached them via breast milk - Rate symptom intensity on a 1–5 scale and add notes - Quick-add repeats foods and symptoms you've used before - Browse a full calendar and day-timeline view - Edit any past entry SEE THE PATTERNS LittleClues turns your log into a ranked view of foods by how often symptoms follow them: Likely trigger · Possible trigger · Unlikely trigger · Needs more data Each food shows a plain-language reaction percentage — "symptoms followed this food on 4 of 6 exposures." You can analyze a single symptom (just rash, just digestive) or see a combined overview. The app also highlights recently introduced foods worth keeping an eye on. BREASTFEEDING-AWARE If you're breastfeeding, what you eat reaches your baby too. LittleClues tracks your diet and your baby's reactions on separate timescales — built from the ground up to handle both. MULTIPLE CHILDREN Track more than one child in the same app. Each child has their own log, food library, and reaction history. Switch between them in a tap. PRIVATE BY DESIGN All your data lives on your device. No account. No login. No server. Back up locally to iCloud, Files, or Google Drive whenever you want — and restore it cleanly on any device. COMING SOON — LITTLECLUES PRO Full per-food analysis, confounding detection (find the real culprit when two foods always show up together), elimination and reintroduction pattern recognition, and a shareable PDF summary for your doctor. Coming as an in-app purchase. 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.
