# Orthopaedic Book vs VPOP® PRO

The clearest difference is review sentiment: VPOP® PRO at 83% against Orthopaedic Book's 25%. VPOP® PRO also leads on rating (5.0 vs 1.0) and update cadence (every 4 weeks vs every 2 months). Orthopaedic Book's advantage is in-app purchases (none vs 4) and iOS requirement (7.1 vs 15.0). On price and ads there is nothing between them.

Both are free to download. VPOP® PRO sells 4 in-app purchases, starting at $15.00 per month. Orthopaedic Book asks for nothing beyond the download.

VPOP® PRO holds the better App Store score, 5.0 against 1.0. That said, the two scores are not equally well evidenced: VPOP® PRO has 7 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 25% of Orthopaedic Book's written reviews are positive against 83% of VPOP® PRO's.
