Smartphone app tests your wee for health problems
A smartphone app that can detect medical conditions by looking at your wee has been shown off in Los Angeles, United States.
The app called Uchek tests for 25 different health issues like diabetes, infections and liver problems.
Users dip a special strip of card into their wee and watch it change colour.
Then they take a photo of the strip with their smartphone and the app works out if there's a problem.
The app was invented by Myshkin Ingawale who said: "I wanted to get medical health checks into users' hands."
The app is expected to cost around £13 which includes five test sticks.
The developers hope it will improve healthcare in developing countries.
Beware though - you don't actually wee on your phone!
