Hi! I see so many posts that have "Fuelly"... but I'm not sure what that's all about? Maybe an app? If so, I have an iPhone 5s... is it compatible? Does it integrate with the Prius itself? I have a 2014 Three. Thanks in advance for your help!!
You can see more about it here: Fuelly - Track and Compare Your MPG They have a mobile interface that works on the iPhone but I use another free app and syncs with Fuelly called GasTracker: GasTracker + on the App Store on iTunes It works well to track your gas mileage and put a banner on forums such as mine below.
