Verdict
The clearest difference is in-app purchases: The Core Effect at none against RF Coaching's 1. The Core Effect also leads on update cadence (every 2 months vs every 5 months). RF Coaching's advantage is device support (3 vs 1). On price, ads and iOS requirement there is nothing between them.
