Verdict
The clearest difference is in-app purchases: Easy Motion Skin at none against Rule's 1. Easy Motion Skin also leads on ads (none vs shown) and iOS requirement (11.0 vs 15.0.0). Rule's advantage is update cadence (every 3 weeks vs every 2 months). On price and device support there is nothing between them.
