Verdict
The clearest difference is update cadence: iDays at every 3 weeks against Countdown's every 10 months. iDays also leads on ratings volume (520 vs 4) and monetization model (free vs ad-supported). Countdown's advantage is rating (5.0 vs 4.8). On price, ads and in-app purchases there is nothing between them.
