# Archie vs Structural Dynamics Visualizer

The clearest difference is in-app purchases: Structural Dynamics Visualizer at none against Archie's 4. Structural Dynamics Visualizer also leads on rating (5.0 vs 4.8). Archie's advantage is ratings volume (15 vs 1) and iOS requirement (17.0 vs 26.5). On price, ads and device support there is nothing between them.

Both are free to download. Archie sells 4 in-app purchases, starting at $2.99 per 7 days. Structural Dynamics Visualizer asks for nothing beyond the download.

Structural Dynamics Visualizer holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Archie has 15 ratings behind it against 1, so its average is the more settled of the two.
