iOS App vs Web from iPhone
 

I've only just discovered the iOS Gas Tracker app. I've been using the web pages to record my fill ups.

On line I have a couple of vehicles one with 87 fillups and the other with 53. The UK MPG is 27 and 29 MPG.

On the App there are only 30 fill ups recorded and the UK MPG is only 6.7

Have I missed a setting?

You may need to force a sync. You can try logging out and back in of GasTracker or pulling down to refresh.

Thanks - thats pulled down all the fill ups.
