A new smartphone app has been developed that can detect a number of medical conditions by looking at your wee.
The app is called the Uchek and has been shown off in Los Angeles, United States.
The app tests for 25 different health issues like diabetes, infections and liver problems.
To use the app people dip a special strip of card into their wee and watch it change colour. They then 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 people – you don’t actually wee on your phone!
