Verdict
The clearest difference is ads: Calculator at none against Reminder & Countdown's shown. Calculator also leads on monetization model (free vs free with in-app purchases) and iOS requirement (13.0 vs 16.0). Reminder & Countdown's advantage is rating (4.8 vs 4.4) and ratings volume (17K vs 5). On price, update cadence, in-app purchases and device support there is nothing between them.
