Sorry you're having trouble.
This was posted in the aCar section, but it sounds like you may be referring to the Fuelly Web App.
We've been receiving reports of the viewing of the main site (when you click on Edit, it takes you away from the mobile site- m.fuelly.com to the main site-
www.fuelly.com.
BUT this is only when using the mobile web app.
We're looking into better optimizing the main site for mobile devices, but for now, you can either bookmark and use m.fuelly.com in a regular browser window on your device, or as you did this time, make your edits once you're near a computer.
