Verdict
The clearest difference is ads: PRO at none against Apex Booking's shown. PRO also leads on update cadence (every 2 weeks vs every 21 months) and ratings volume (109 vs 1). Apex Booking's advantage is device support (3 vs 1). On price, rating, in-app purchases and iOS requirement there is nothing between them.
