# OrthoGuidelines vs Implant Identifier

The clearest difference is review sentiment: OrthoGuidelines at 100% against Implant Identifier's 63%. OrthoGuidelines also leads on monetization model (free vs free with in-app purchases) and rating (4.9 vs 4.7). Implant Identifier's advantage is ratings volume (269 vs 11) and update cadence (every 3 weeks vs every 2 months). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

OrthoGuidelines holds the better App Store score, 4.9 against 4.7. That said, the two scores are not equally well evidenced: Implant Identifier has 269 ratings behind it against 11, so its average is the more settled of the two. Written reviews point the same way: 100% of OrthoGuidelines's written reviews are positive against 63% of Implant Identifier's.

OrthoGuidelines ships an update every 2 months, Implant Identifier every 3 weeks. Both last shipped on October 24, 2026.
