# SH1FT vs OSTEO

The clearest difference is rating: SH1FT at 4.9 against OSTEO's 2.4. SH1FT also leads on in-app purchases (none vs 3). OSTEO's advantage is review sentiment (36% vs 20%) and update cadence (every 8 days vs every 3 weeks). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. OSTEO sells 3 one-off in-app purchases. SH1FT asks for nothing beyond the download.

SH1FT holds the better App Store score, 4.9 against 2.4. That said, the two scores are not equally well evidenced: OSTEO has 48 ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 20% of SH1FT's written reviews are positive against 36% of OSTEO's, so the app with the better star average is not the one people write more warmly about.

SH1FT ships an update every 3 weeks, OSTEO every 8 days. The most recent releases landed on October 24, 2026 and October 22, 2026 respectively.
