Verdict
The clearest difference is ads: GymJam at none against Plank Workout Challenge's shown. GymJam also leads on update cadence (every 11 days vs every 5 months) and rating (5.0 vs 4.8). Plank Workout Challenge's advantage is ratings volume (129 vs 1) and iOS requirement (12.0 vs 18.0). On price, in-app purchases, monetization model and device support there is nothing between them.
