# Captioo vs Docker Guard

The clearest difference is in-app purchases: Captioo at none against Docker Guard's 1. Captioo also leads on iOS requirement (12.2 vs 26.4). Docker Guard's advantage is device support. On price there is nothing between them.

Both are free to download. Docker Guard sells 1 one-off in-app purchase. Captioo asks for nothing beyond the download.
