Verdict
The clearest difference is rating: Ruler at 3.5 against Epic Ruler's 1.0. Ruler also leads on review sentiment (40% vs 0%) and update cadence (every 3 weeks vs every 17 months). Epic Ruler's advantage is in-app purchases (none vs 4). On price, ads and device support there is nothing between them.
