Verdict
The clearest difference is in-app purchases: SumDU at none against Countdown Reminder's 1. SumDU also leads on ads (none vs shown) and iOS requirement (12.1 vs 15.0). Countdown Reminder's advantage is update cadence (monthly vs every 8 months). On price, review sentiment and device support there is nothing between them.
