# Ruler vs SUBDossier

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

Both are free to download. Ruler sells 1 one-off in-app purchase. SUBDossier asks for nothing beyond the download.
