Verdict
The clearest difference is ads: Map Discovery at none against Quindecuple Calc's shown. Map Discovery also leads on iOS requirement (12.0 vs 15.8.3). Quindecuple Calc's advantage is update cadence (every 2 weeks vs every 6 weeks). On price, in-app purchases and device support there is nothing between them.
