# Reaction Time vs Block Tidy

The clearest difference is in-app purchases: Block Tidy at none against Reaction Time's 1. Block Tidy also leads on iOS requirement (13 vs 15.6). Reaction Time's advantage is device support (5 vs 3). On price and ads there is nothing between them.

Both are free to download. Reaction Time sells 1 one-off in-app purchase. Block Tidy asks for nothing beyond the download.
