# PRO vs Apex Booking

Apex Booking's advantage is device support (3 vs 1). On price, rating, in-app purchases and iOS requirement there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

PRO ships an update every 2 weeks, Apex Booking every 21 months. The most recent releases landed on October 26, 2026 and October 7, 2026 respectively.
