# BIO vs Διαβαστούλης

The clearest difference is device support: BIO at 3 against Διαβαστούλης's 1. BIO also leads on iOS requirement (15.6 vs 17.0). 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.
