What agrees with you? Your diary helps you find out.

How it works

Here's how: log your food, note your symptoms, spot the patterns.

Step 01

Log your meals

Log what you ate and when.

Step 02

Note your symptoms

Note which symptoms you had and how strong they were.

Step 03

Spot patterns

Eatolerance compares your entries and shows what stands out on days with and without certain food components.

Example analysis

What a result can look like

Lactose Gut strong

You had symptoms on 22 of 25 days with lactose - and on 2 of 31 days without lactose.

With lactose 22/25
Without lactose 2/31

On days with lactose the symptoms were stronger too: 5 out of 10 on average instead of 0. The more lactose, the stronger the symptoms.

To check: Look for a meal that contains lactose but none of the other suspects. Until then the diary cannot tell them apart, however long it gets.
Features

A diary that does the thinking.

A food catalogue with over 1500 entries

With portion sizes, allergens and possible components. If a food is missing, you can add it.

Amounts are taken into account

The analysis factors in how much of a component you ate.

Record your symptoms

Note your symptoms and how strong they were, on a scale from 0 to 10.

A diary for several people

Keep a separate diary for each person in the family - and share a profile with a code so you can log entries together.

Foods at a glance

Drawn pictures and portion sizes help you recognise entries quickly.

Six languages

German, English, Spanish, French, Italian and Portuguese - with the right food names and synonyms.

Questions

Who is Eatolerance for?

For anyone who wants to know how they react to lactose, fructose, histamine, gluten or FODMAPs - for example with IBS or histamine intolerance.

Does the app make a diagnosis?

No. It shows patterns in your diary - a good starting point for a conversation with your doctor.

How long do I need to keep a diary?

The more days with and without a component you collect, the clearer the picture. If it is not enough yet, the app tells you so.
