This app is a great tool replacing your car log book and great for tax purposes when you want to show usage of vehicle to the Tax man. It’s also great for those of us that like to keep a track of the kilometres we do for business or personal use in our vehicles. At the beginning of your journey just input your speedometer reading and reason for the trip, select if it’s a business trip or personal, then press Start. The app will automatically keep the date and time of the event and will also calculate the kilometres you do from start to finish, so at the end of your journey just click finish and you are done till the next time. You will also be able to print the report or email it to your accountant. Once you have tested it a few times and like the functionality and convenience you may want to throw away your current log book and use your Car Mileage 101 instead. Enjoy!
