# CGX vs OSTEO

The clearest difference is rating: CGX at 4.2 against OSTEO's 2.4. CGX also leads on review sentiment (55% vs 36%) and ratings volume (642 vs 48). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. CGX sells 2 in-app purchases, starting at $12.99 per month and OSTEO sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

CGX holds the better App Store score, 4.2 against 2.4. That said, the two scores are not equally well evidenced: CGX has 642 ratings behind it against 48, so its average is the more settled of the two. Written reviews point the same way: 55% of CGX's written reviews are positive against 36% of OSTEO's.

Both ship on a similar rhythm, roughly every 8 days. The most recent releases landed on October 30, 2026 and October 22, 2026 respectively.
