# SkinIO vs CrewFit+

The clearest difference is in-app purchases: SkinIO at none against CrewFit+'s 5. SkinIO also leads on ratings volume (63 vs 3). 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.

Both are free to download. CrewFit+ sells 5 in-app purchases, starting at $1.99 per month. SkinIO asks for nothing beyond the download.

CrewFit+ holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: SkinIO has 63 ratings behind it against 3, so its average is the more settled of the two. Written reviews point the same way: 96% of SkinIO's written reviews are positive against 100% of CrewFit+'s.

SkinIO ships an update monthly, CrewFit+ every 10 days. The most recent releases landed on October 20, 2026 and October 5, 2026 respectively.
