Verdict
The clearest difference is in-app purchases: Just Workout at none against Plank Challenge's 1. Just Workout also leads on iOS requirement (9.3 vs 18.0). Plank Challenge's advantage is update cadence (every 3 months vs every 20 months). On price, ads and device support there is nothing between them.
