Verdict
The clearest difference is rating: One Calendar at 4.8 against Year View Planner's 2.0. One Calendar also leads on ratings volume (21K vs 1) and iOS requirement (15.0 vs 17.0). Year View Planner's advantage is in-app purchases (none vs 1). On price, update cadence, ads and device support there is nothing between them.
