Calculations are accurate and reliably match target values.
Clear default data entry and simple, efficient UI that speeds up fueling calculations.
Strong overall user sentiment; frequently described as the best/easiest E85 calculator available.

This app is definitely the best out there, thank you for making our lives easier. I am saying this as a recommendation for a small feature. I’m not sure if others have the same problem, but it would be nice to be able to set the target fuel amount in the tank. Right now, the calculator gives you the number of gallons to add in order to get to a full tank. But for those that are racing competitively and maybe don’t want the added weight of a full tank, it would be nice to say, for example: “I want 1/2 full of a tank and I’m at 1/4, how much ethanol and pump gas do I need to add?” Hopefully that make sense. Thanks!

I’ve been using this for quite awhile now and it works great! I guess the math doesn’t lie but I’m always surprised at how accurate to my target it is.

This app is excellent. The best app that I have found. The layout is perfect to easily enter default information. The slide bar was a brilliant idea to enter the key variable whenever you go to fill up. Much quicker than typing in the % of fuel remaining in the tank. Enhancement that would really finish/polish this app: The E85 stations in my area (NJ) do not allow you to pump in a specific number of gallons. You have to enter the dollar amount of fuel that you want, and exactly that dollar amount is pumped into the tank. So the current app forces me to exit and use the calculator app to multiply the number of gallons times the price per gallon. A great enhancement would be to add default fields for the price per gallon of ethanol and of gasoline. Then in the calculated results show the gallons of ethanol needed along with its total cost. And do the same for gasoline results. Hope that you will consider this enhancement. It would make your app the absolute easiest/quickest to use when pulling in to a station to fill up. Right now, I park on the side first to use the app and then the calculator app to have the total price before pulling up to the pump. Don’t want to be that jerk who isn’t prepared and takes forever while other people are waiting to get gas. Thanks again!
