About this app

LittleClues is a food allergy tracker and symptom diary built for parents of
babies and toddlers. If you're trying to figure out which food is behind
your baby's reactions, LittleClues turns your food and symptom log into a
ranked list of likely triggers — so you're working from patterns, not guesswork.

WHY PARENTS USE A FOOD ALLERGY TRACKER

Foods get eaten together, symptoms show up on a delay, and if you're
breastfeeding, what you eat matters too. Whether you're running a full elimination diet or just watching one suspect food, a casual food diary can't keep up with all of that. LittleClues is a baby food tracker and allergy journal
built specifically to handle it — logging both what your child ate and how
they felt, on the same timeline.

LOG FOOD AND SYMPTOMS IN SECONDS

- Log meals and symptoms as dated, timed entries
- Track food your baby ate directly, or food that reached them through
breast milk if you're breastfeeding
- Rate symptom severity on a simple 1–5 scale and add notes
- Quick-add foods and symptoms you've logged before
- Browse a full calendar and day-by-day timeline
- Edit any past food or symptom entry

FIND YOUR BABY'S LIKELY ALLERGY TRIGGERS

LittleClues ranks the foods in your log by how often symptoms followed them:
Likely trigger, Possible trigger, Unlikely trigger, or Needs more data. Each
food shows a plain-language reaction rate, like "symptoms followed this food
4 of 6 times." Look at one symptom at a time — just rash, just digestive
upset — or see a combined view across all symptoms.

A BREASTFEEDING-AWARE ALLERGY TRACKER

Reactions in breastfed babies can come from something the mother ate, not
just something the baby ate directly, often a day or more later. LittleClues
tracks a mother's diet and a baby's food intake separately, scored on their
own timescales, because those two kinds of reactions show up differently.
Built specifically for parents managing cow's milk protein allergy (CMPA),
food intolerance, or suspected sensitivities while breastfeeding.

TRACK MULTIPLE CHILDREN

Manage more than one child in the same app, each with their own food log,
symptom history, and caregiver profile. Switch between children in a tap.

PRIVATE, LOCAL-FIRST FOOD AND SYMPTOM DIARY

All your data — food entries, symptoms, profiles, settings — stays on your
device. No account required, no login, no server. Back up your log to
Google Drive whenever you want, and restore it later on any device.

What’s new

Safe foods: mark what you already know is fine, and it stays out of Foods to watch.

Insights rebuilt. A clearer five-level scale — very low to very high — replaces the old labels, and percentages are gone. You now see the actual counts from your log, next to the same counts for ordinary days, so you can see what the rating is based on.

New plain-language explanations throughout, and you can now view one symptom at a time inside a food's detail.
