Yes, it's the standard page count for all their 32page books. 18-20 pages (really less since I believe the 'previously' page is counted in that), and the rest is ads.Even on the $3.99 books? I misunderstood - I thought that was on the cheaper books. Wow.
I didn't mind it at first, but when they do a lot of boring things and then have an app that barely works, I stopped with it completely.It's meaningless to me. It's not interesting or compelling enough to make me feel like paying an extra dollar is worth it.
