As it says in the description, it acts as a wireless keyboard and touchpad for your computer. All that you have to do is download the server software on your computer. What's great about this app is just the simplicity of it. The app itself is very small, taking up a minuscule 42 kb on your phone. The program for your computer is also very small, it takes up only 135 kb and you don't need to install anything, it is a self contained Java program. There is no option to auto-start the program when your computer turns on but this can be solved by just adding a shortcut of the program to your Startup folder. However, the main thing that really bothers me about this app is that you can't make the server run in the background on your computer like a similar app, Gmote. You can have the window minimized but it must always be running or else the app will stop working. Overall, if you are just looking for a simple app to act as a touchpad and wireless keyboard for your computer, this is what to go with. However, if you want more features and an overall more polished product, I would suggest going with Gmote. However, the app and the program are open-source so hopefully we may soon see some of the features that this is lacking.
