Avoid using the latest version of the GasBuddy app on your iPhone. The developer admits it is causing problems and has temporarily withdrawn it from the App Store until a fix can be released.

UPDATE: A fixed version of GasBuddy is available on the App Store. Users of this service should install this new version immediately.

GasBuddy lists crowdsourced gasoline prices. It’s free and useful enough to make our list of 50 essential iOS apps.

It’s road trip season, and that means gas prices can have a big impact on your vacation. Sometimes what seems like a decent gas price is actually a ripoff because you don’t know about the local station around the corner that’s selling fuel for far less.

If you want to get the best gas price, use GasBuddy for iPhone. The app shows you where all the nearby gas stations are. Better still, GasBuddy helps you find the best prices on gas, wherever you are.
