Hi Guys A little app using Nicolas's gw library. M.P.G: To use this app first fill your vehicle up to the top with fuel and set the mile counter to zero. When read to refuel, fill up to the top again and make a note of the miles traveled, pence per litre and litres used. Apart from miles traveled, the other information will be on your receipt . Put the three pieces of information into the app and press Calculate. The app will then display the MPG and other information about the fuel costs of your vehicle. Most of the information and the date is saved to a history file, and is reloaded each time you run the app. As long as you always fill your vehicle up to the top and zero the miles counter and enter the information into the app, you will have a record of your vehicle's fuel costs. On low resolution devices the history box may not look right. If this is the case, try holding the device horizontally. To test try: Miles Traveled 208.5 Pence Per Litre 119.7 Litres Used 15.6 Many thanks to Nicolas for his gw library, and help with this project. Regards Roy
