# My Skyhook vs OnlyStrength

The clearest difference is in-app purchases: My Skyhook at none against OnlyStrength's 2. My Skyhook also leads on review sentiment (100% vs 83%) and rating (5.0 vs 4.8). OnlyStrength's advantage is ratings volume (27 vs 2) and update cadence (every 10 days vs every 4 weeks). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. OnlyStrength sells 2 in-app purchases, starting at $34.99 per month. My Skyhook asks for nothing beyond the download.

My Skyhook holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: OnlyStrength has 27 ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 100% of My Skyhook's written reviews are positive against 83% of OnlyStrength's.
