Apps that ask 'what's wrong?' are AI behind the scenes. They can be wrong. Always tell a grown-up too.
7 min · Reviewed 2026
The big idea
Symptom-checker apps use AI to guess what might be wrong with you. They can miss serious things or scare you about nothing. They are a clue, not an answer.
Some examples
An app might say a tummy ache is one of 20 things
Some real serious problems do not match the app's questions
An app saying 'probably nothing' is not a doctor saying that
If you feel really bad, tell a grown-up — do not just trust the app
Try it!
Make a rule: 'If I feel bad enough to use an app, I will tell a parent too.' Say it out loud.
