# Visual Vertical vs Scoliosis Tools

The clearest difference is review sentiment: Visual Vertical at 100% against Scoliosis Tools's 36%. Visual Vertical also leads on ratings volume (5 vs 1). Scoliosis Tools's advantage is rating (5.0 vs 2.0) and price ($4.99 vs $11.99). On ads, in-app purchases and monetization model there is nothing between them.

Visual Vertical costs $11.99 and Scoliosis Tools $4.99 up front. Neither carries in-app purchases, so what you see is what you pay.

Scoliosis Tools holds the better App Store score, 5.0 against 2.0. That said, the two scores are not equally well evidenced: Visual Vertical has 5 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 100% of Visual Vertical's written reviews are positive against 36% of Scoliosis Tools's, so the app with the better star average is not the one people write more warmly about.

Visual Vertical ships an update every 38 months, Scoliosis Tools every 2 months. Both last shipped on October 26, 2026.
