HTML/PhoneGap App Ideas

I'm gathering ideas for upcoming PhoneGap projects in 2013. What apps would you like to see developed/cloned in HTML/PhoneGap? These ideas will be used for performance comparisons of hybrid and native applications, how-to guides, or could be used for sample app projects. Please specify details below, all ideas are welcome.

Thank you!
