# Clue Formula vs Arrow Loop

The clearest difference is ads: Arrow Loop at none against Clue Formula's shown. Clue Formula's advantage is device support (4 vs 1) and iOS requirement (15.0 vs 17.0). On price and in-app purchases there is nothing between them.

Both are free to download. Clue Formula sells 2 one-off in-app purchases and Arrow Loop sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
