Verdict
The clearest difference is ads: Countdown Days at none against Super Calc Pro+'s shown. Countdown Days also leads on iOS requirement (15.6 vs 17.0). Super Calc Pro+'s advantage is update cadence (every 2 weeks vs every 5 weeks). On price, in-app purchases and device support there is nothing between them.
