Useful but needs work on data entry

This app is perfect apart from one thing. It forces you to put both the beginning and ending odometer miles in at the beginning of the trip. My last trip I put the beginning miles in and guesstimated on the ending miles thinking I would just adjust the ending miles at the end of the trip. But once you put the beginning and ending miles in, you then get total miles. So when I adjusted the ending milage at the end of the trip, the total miles remained the same and changed my beginning miles. I then lost my initial odometer reading.... Data entry could be made much easier.
