Verdict

The call

The clearest difference is update cadence: 30 day at every 9 days against Plank Challenge's every 3 weeks. 30 day also leads on review sentiment (75% vs 66%) and iOS requirement (13.0 vs 16.0). Plank Challenge's advantage is ratings volume (472 vs 155). On price, rating, ads and in-app purchases there is nothing between them.
