Verdict
The clearest difference is in-app purchases: TimeSpanCalc at none against Countdowner's 1. TimeSpanCalc also leads on iOS requirement (12.0 vs 18). Countdowner's advantage is update cadence (every 9 days vs every 3 weeks). On price, review sentiment, ads and monetization model there is nothing between them.
