# ™ Go vs Echo

The clearest difference is device support: ™ Go at 3 against Echo's 1. ™ Go also leads on iOS requirement (13.0 vs 16.0). On price, ads and in-app purchases there is nothing between them.

Both are free to download. ™ Go sells 1 one-off in-app purchase and Echo sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
