Verdict
The clearest difference is rating: OnePrep at 4.7 against uSafeHS's 3.3. OnePrep also leads on update cadence (every 5 days vs every 3 months) and ratings volume (701 vs 24). uSafeHS's advantage is in-app purchases (none vs 23) and ads (none vs shown). On price and device support there is nothing between them.

Both are free to download. OnePrep sells 23 in-app purchases, starting at $28.49 per 7 days. uSafeHS asks for nothing beyond the download.
OnePrep holds the better App Store score, 4.7 against 3.3. That said, the two scores are not equally well evidenced: OnePrep has 701 ratings behind it against 24, so its average is the more settled of the two. Written reviews complicate that: 67% of uSafeHS's written reviews are positive against 45% of OnePrep's, so the app with the better star average is not the one people write more warmly about.
uSafeHS ships an update every 3 months, OnePrep every 5 days. The most recent releases landed on October 6, 2026 and October 25, 2026 respectively.
