The everyday puzzle

Some days you feel fine. Others you don’t — and the reason is rarely obvious.

The cause and the symptom are often days apart, tangled up with sleep, stress and a dozen meals. That’s exactly the kind of pattern a person can’t hold in their head — but software can. Log what happens; let the correlation engine find what connects.

How it works

Three steps, a few minutes a day.

  1. 1

    Log

    Quickly record meals, symptoms, medication, sleep, stress and more — in seconds, from your phone.

  2. 2

    Correlate

    Our AI engine works in the background, weighing thousands of possible links between what you do and how you feel.

  3. 3

    Know

    See your most likely triggers ranked clearly — and take a report to your GP, dietitian or consultant.

Wherever you’re starting from.

mySymptoms isn’t only for one condition. It meets you where you are.

“After years of blaming gluten, mySymptoms showed me it was onions and garlic all along. Four weeks of logging did what a decade of guessing couldn’t.”
