I have issues. I love to track automobile data like mpg, oil changes, and other service information.
I have been using a Twitter app called MyMileMarker. Their software reads direct twits with mileage, gallons, and price. It has a few bugs. I had a little trouble getting responses confirming that the data was received. MyMileMarker also does not allow for recording service items. I like to track oil changes and tire rotations also.
A few days ago I found Gas Cubby. Here is a direct link via iTunes.
Gas Cubby fills the bill for me. It allows for multiple vehicles and tracks all your fuel fill-ups & vehicle service records. The options are endless. I enjoy being able to track Octane. My Mini Copper S requires a high grade of fuel and being able to track mileage when I don’t fill it with Premium is great. My new Jeep has a a life time warranty, assuming I keep good service records. Gas Cubby allows for export in .csv. Making and annually service log will be simple.
Good luck Gas Cubby. Worth every penny to me.
