# Z vs Cataclysm

The clearest difference is in-app purchases: Cataclysm at none against Z's 4. Cataclysm also leads on ads (none vs shown). Z's advantage is device support (3 vs 1) and iOS requirement (13.0 vs 17.0). On price there is nothing between them.

Both are free to download. Z sells 4 one-off in-app purchases. Cataclysm asks for nothing beyond the download.
