Verdict
The clearest difference is in-app purchases: Smart Aqua at none against ARuler's 1. Smart Aqua also leads on update cadence (monthly vs every 3 months) and ratings volume (7 vs 1). ARuler's advantage is iOS requirement (11.0 vs 13.0). On price, rating, ads and monetization model there is nothing between them.
