# YAML Tools vs JSON Viewer Pro

The clearest difference is chart position: YAML Tools at #1 against JSON Viewer Pro's unranked. YAML Tools also leads on price ($0.99 vs $2.99) and iOS requirement (15.6 vs 17.0). On ads, in-app purchases and device support there is nothing between them.

YAML Tools costs $0.99 and JSON Viewer Pro $2.99 up front. Neither carries in-app purchases, so what you see is what you pay.
