# CraftOS vs SDK85

The clearest difference is rating: CraftOS at 4.8 against SDK85's 4.0. CraftOS also leads on ratings volume (17 vs 1) and chart position (#192 vs unranked). SDK85's advantage is in-app purchases (none vs 1) and update cadence (every 2 weeks vs every 4 months). On price, ads, monetization model and device support there is nothing between them.

Both are free to download. CraftOS sells 1 one-off in-app purchase. SDK85 asks for nothing beyond the download.

CraftOS holds the better App Store score, 4.8 against 4.0. That said, the two scores are not equally well evidenced: CraftOS has 17 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 88% of CraftOS's written reviews are positive against 100% of SDK85's, so the app with the better star average is not the one people write more warmly about.

CraftOS ships an update every 4 months, SDK85 every 2 weeks. The most recent releases landed on October 6, 2026 and October 12, 2026 respectively.
