Verdict
The clearest difference is price: Cylinders at Free against Rules!'s $2.99. Cylinders also leads on ratings volume (1.3K vs 67) and iOS requirement (12.0 vs 15.2). Rules!'s advantage is ads (none vs shown) and review sentiment (71% vs 58%). On rating, update cadence, in-app purchases and device support there is nothing between them.
