Race Fuel Calculator is a full version Android app designed to take the guesswork out of calculating the fuel needed for races. The app provides a quick and easy way to calculate the amount of fuel required for a race, as well as how much fuel to add at the pitstop if needed.

The app is based on a spreadsheet created by HankBizzle, with modifications made by Joe Blow to round up the calculations to always include the final lap of the race. The jQuery data spinner updates the calculations in real-time, without the need for a submit button. With Race Fuel Calculator, you can easily determine the total laps including the final lap after the time runs out, making it a must-have for any racing enthusiast.

Overall, Race Fuel Calculator is an excellent tool for anyone looking to streamline their fuel calculations for races. It's easy to use, accurate, and saves time by providing real-time updates.
