Help is no help

Following the Help instructions for my first log and I kept getting a pop-up message that says Start OD reading higher than End OD reading resulting in negative mikes traveled. Please correct before proceeding. The Help file states you begin the by putting in the Start OD on your first full up and then on your next full up put in the End OD and so on, so I’m not sure what the issue is. Definitely not an intuitive UI. The pop-up ads are obnoxious. I have no problem with regular ads on a free app, but the frequency of these pop-up ads coupled with the confusing interface make me want to delete this app.
