RemoteYun is an application that will allow you, after you create an account on "remoteyun.com", to remotely control all the Arduino Yun pins over Internet, wherever you are, without the need for local server, and without any programming knowledge. You only have to connect whatever you want to Arduino pins and control it with this application. You can assign each pin one of the allowed modes to choose between: Analog Input, Digital Output, PWM output, you can also assign an alias to each pin and a measure unit and an amplification/attenuation factor for Analog Inputs.
