# Chatto vs StructaPin

The clearest difference is device support: StructaPin at 3 against Chatto's 1. StructaPin 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. Chatto sells 4 in-app purchases, starting at $7.99 per 7 days and StructaPin sells 2 in-app purchases, starting at $7.99 per month. Whichever you choose, the download price is not the number that matters.
