A Japanese firm has created a toilet that can be controlled from a smartphone.

The toilet goes on sale in the Spring, and it can be completely controlled by a smartphone app, which can also track user's bowel movements for health reasons.

The app can control all of the toilet's functions, even raising and lowering the lid.

It uses Bluetooth to communicate with the mobile phone app, and can even play music through speakers built into the toilet’s base.

The app will be available for selected Android phones under the app name, “My Satis.”

Every feature including flushing, lifting the toilet seat, and spraying can be controlled.
