I use and like my flight book,free,easy to use ,very handy have it on the IPad ,also have foreflight on the iPad so I always have my log book handy. Usually copy the info in a hard copy log book regularly .
I too use MFB. Wanted to look into Pilotica to compare but their sign-up page is a little strange. Probably just a glitch in the Matrix.
Besides the MFB and my paper logbook, I also have an Excel spreadsheet that mimics the paper logbook precisely which allows me to double-check the math in the entries. If those 3 copies of my logs disagree, something is amiss.
