I use LogTen Pro for Mac products and I love it. Their customer service is fantastic and I've been pleased with the product ever since 2009.

I used a printed logbook from LogTen for my interview at Delta. All you have to do is select the style you want, save it and send it to a FedEx print store. I had it printed on 8.5 x 11 card stock and had it bound and covered. Looks amazing!
