I used to use Fuelly a lot on my old Palm Pre and the mobile site worked fine. When I attempted to access m.fuelly.com on my iPhone 4S today it comes up blank. The regular site works fine but is pretty tiny and hard to use. Is the mobile site not compatible with iOS5?
The mobile site at m.fuelly.com works fine on iOS5. Maybe it's a problem with your connection? I can't think of an issue offhand that would make the site come up blank for you beyond a network problem.
I have an iPhone 4 and the Fuelly mobile app tends to do this from time to time (once every few weeks or so). A few tips to try: close app and try again, delete app and reinstall, do a soft reset of the phone, or close all other apps in multitasking tray. Trying these should fix that... If not, it really could be the site.
Thanks for the tips jmp316. But just to clarify, there is no native Fuelly app. There's the Fuelly Mobile website at m.fuelly.com. If you've installed a shortcut to Fuelly Mobile on your Home Screen you can remove and re-add that if you want to, but there's no app to install/reinstall.
