The clearest difference is rating: Structural Navigator at 5.0 against OrthoGraph's 2.4. Structural Navigator also leads on review sentiment (50% vs 13%) and in-app purchases (none vs 11). OrthoGraph's advantage is update cadence (every 2 weeks vs every 5 months) and ratings volume (9 vs 1). On price, ads and device support there is nothing between them.

Both are free to download. OrthoGraph sells 11 in-app purchases, starting at $9.99 per month. Structural Navigator asks for nothing beyond the download.

Structural Navigator holds the better App Store score, 5.0 against 2.4. That said, the two scores are not equally well evidenced: OrthoGraph has 9 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 50% of Structural Navigator's written reviews are positive against 13% of OrthoGraph's.
