# Z80CPM vs Sensor

The clearest difference is device support: Z80CPM at 4 against Sensor's 2. Z80CPM also leads on iOS requirement (15.0 vs 18.0). On price, ads and in-app purchases there is nothing between them.

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