Verdict
The clearest difference is in-app purchases: Rummi Countdown Timer at none against JDP's 6. Rummi Countdown Timer also leads on ratings volume (10 vs 2) and iOS requirement (12.0 vs 14.2). JDP's advantage is review sentiment (100% vs 83%) and rating (5.0 vs 4.8). On price, update cadence, ads and device support there is nothing between them.
