Verdict
The clearest difference is price: RulerBasic at Free against Ruler App's $0.99. RulerBasic also leads on update cadence (fortnightly vs every 11 months). Ruler App's advantage is in-app purchases (none vs 4) and iOS requirement (12.0 vs 16.0). On ads and device support there is nothing between them.
