# Prometheus vs ExactAge

The clearest difference is device support: ExactAge at 4 against Prometheus's 2. ExactAge also leads on iOS requirement (15.0 vs 17.6). 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.
