# Gadget Set vs Key Calculator

The clearest difference is in-app purchases: Key Calculator at none against Gadget Set's 1. Key Calculator also leads on ads (none vs shown). On price, device support and iOS requirement there is nothing between them.

Both are free to download. Gadget Set sells 1 one-off in-app purchase. Key Calculator asks for nothing beyond the download.
