# nTube vs Skeleton 3D Anatomy

The clearest difference is in-app purchases: nTube at none against Skeleton 3D Anatomy's 8. nTube also leads on ads (none vs shown) and iOS requirement (8.2 vs 15.0). Skeleton 3D Anatomy's advantage is ratings volume (345 vs 4) and update cadence (every 6 months vs every 20 months). On price, rating, review sentiment and monetization model there is nothing between them.

Both are free to download. Skeleton 3D Anatomy sells 8 in-app purchases, starting at $2.99 per 7 days. nTube asks for nothing beyond the download.

Skeleton 3D Anatomy holds the better App Store score, 4.4 against 4.3. That said, the two scores are not equally well evidenced: Skeleton 3D Anatomy has 345 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 60% of nTube's written reviews are positive against 57% of Skeleton 3D Anatomy's, so the app with the better star average is not the one people write more warmly about.

nTube ships an update every 20 months, Skeleton 3D Anatomy every 6 months. The most recent releases landed on October 23, 2026 and October 24, 2026 respectively.
