Downloading xPocket 2.0 for Mac from our website was free. The actual developer of this free Mac application is Art Coughlin. The application lies within System Tools, more precisely Device Assistants.
From the developer:
xPocket helps you to control an X-10 Model CP290 computer interface from an iPod Touch, iPhone, or iPad. Install xPocket on a Mac with an attached CP290. Nothing is installed on your iDevice and it doesn't need to be jail-broken. You will have to edit an HTML file, but HTML skills are not necessary.
You may want to check out more Mac applications, such as Portable Nvu or Matchprint Virtual, which might be related to xPocket.
