Verdict
The clearest difference is in-app purchases: SkinIO at none against CrewFit+'s 5. SkinIO also leads on ratings volume (64 vs 7). CrewFit+'s advantage is rating (5.0 vs 4.6) and update cadence (every 10 days vs monthly). On price, review sentiment, ads and device support there is nothing between them.
