Back in May, Adam covered a great business expense tracking application, ProOnGo Expense. Recently, the app has been updated with a major feature, enabling users to use their built-in GPS to track their mileage. In the new version, users simply open up a new mileage expense and the app will use the GPS to determine the start and end locations, calculating the mileage automatically. An excellent resource for business users on the go, the app also helps track receipts using the camera to capture the information, and even includes reminders to make sure you get that expense report in on time. There is support for various units of measurement, currencies and more, ensuring that each user can tailor the application to their individual needs. Available in the CB store as a free download for multiple devices running OS 4.5 and up, including OS 6 support.
