Crash w/ iOS 8 and iPhone 6 - Fix Inside!
 

GasTracker opens on my iPhone 6 with an Error pop up that just says Error. Press OK and another popup says I have been logged out due to changed user credentials. The app then crashes. Help!

Found the fix. Delete the app and agree to remove all files. Go to App Store search for GasTracker + and redownload. Sign back in and all is well.

Thanks for reporting your issue and the "fix". The more info we get back like this from our users, the better. It's much appreciated.

Hey, this just worked for me too! I have an iPhone 6 with IOS 8, and was crashing non-stop. Deleting, re-downloading, and re-installng worked! Thanks!!

I had this issue with the iphone 6 plus - 128gb gold at&t. I imagine its an ios 8 issue itself and the transfering of an actively logged in app, which came from the backup. Anyways, Glad this fixed it because it was really annoying.

Same here... iOS8 worked fine but on the iPhone 6 with ios8 I get the same errors as above.

Thanks for the advice. I was having trouble, constant crashing, with a iPhone 6 Plus, deleting and reinstalling fixed it.

I followed the instructions but now am NOT able to login. Can you please help?

Sorry for the frustration! Based on the reports we're getting it seems there's something going on with the download process from the App Store.

Could you completely kill the app, uninstall GasTracker, hard reset your device (don't worry, no data loss by doing this) and then download GasTracker again.
To hard-reset, press and hold both the Sleep/Wake and Home buttons for at least 10 seconds, until you see the Apple logo.

Let me know if you continue to have issues!

Great! I just did the fix. Thanks for the help.
