How AllerLog works

From a quick log to a clear answer.

Built for that messy minute right after a feed, when one hand's on the spoon and the other's on your phone. Log the meal, add two quick scores, and the foods worth watching start to stand out on their own.

Logging a baby meal in AllerLog — meal type, an ingredient library of carrot, spinach, sweet potato and more, and a taste rating.
01 · Log

Log a meal in seconds.

Add breakfast, lunch, dinner or a snack. Pick from a built-in ingredient library or add your own, set the time, and rate how they liked it.

AllerLog sleep and poop scoring — rating sleep from restless to deep and poop from abnormal to normal on a 1 to 5 scale after a meal.
02 · Score

Add a sleep & poop score.

Rate sleep and poop 1–5 after a meal. Those two scores are the real clue: they're how AllerLog ties a food to a rough night or an unsettled tummy.

AllerLog per-ingredient chart — a graph built from meal scores showing how a single ingredient lines up with good and bad days.
03 · See

See every ingredient's chart.

Per-ingredient graphs, built from your scores, show at a glance which foods line up with good days and which don't. Filter by favorite and least favorite.

AllerLog AI Insights screen surfacing possible food intolerances — lowest-scoring ingredients like milk and egg flagged across multiple meals.

Why parents love AllerLog

Find the food behind the fuss.

No. 01

Find hidden triggers.

See which ingredients line up with poor sleep or an unsettled tummy. The foods that don't agree with your little one are easy to miss day to day, but they're hard to hide once they're sitting there in the data.

No. 02

Sleep & poop are the clue.

A rough night or a difficult nappy is often the first sign a food doesn't agree. Rate sleep and poop 1–5 after meals and AllerLog uses those scores to connect symptoms back to specific ingredients.

No. 03

AI-powered insights.

AllerLog's AI reviews your logged meals and reasons through the data across sleep, poop and mood, flagging possible allergies and intolerances you might miss and explaining the pattern in plain words.

No. 04

Stay one step ahead.

Mark any ingredient as an allergen and get follow-up reminders whenever you introduce a new food or one you've flagged, so you can pace introductions on whatever schedule your pediatrician suggests.
