Cri Cri is a free multimedia application developed by Daniel Souza, which is designed to use the light sensor to emit a cricket sound. This app can be used to play pranks on friends and family by turning the light on and off. The application emits a cricket sound when it detects low light and stops emitting the sound when it detects light.

The app is simple to use and perfect for those who want to add some fun to their daily routine. The app can only be used on devices that have a light sensor. So, if you have a compatible device, download Cri Cri and start playing pranks on your friends and family.
