You might have heard of the application called TorchButton if you happen to own a device with a flash equipped camera. The good news is that TorchButton has evolved to version 2.0 which brings HD2 support to the application.

It basically turns on the camera’s flash and enables you to have a torch-like flashlight which stays on as long as the application is running. When you want to turn it off, just launch the application again. That’s all!
