# LockDown Browser vs McGraw Hill Express Library

The clearest difference is rating: McGraw Hill Express Library at 2.7 against LockDown Browser's 1.2. LockDown Browser's advantage is update cadence (every 5 weeks vs every 4 months) and ratings volume (4K vs 153). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

McGraw Hill Express Library holds the better App Store score, 2.7 against 1.2. That said, the two scores are not equally well evidenced: LockDown Browser has 4K ratings behind it against 153, so its average is the more settled of the two. Written reviews complicate that: 8% of LockDown Browser's written reviews are positive against 3% of McGraw Hill Express Library's, so the app with the better star average is not the one people write more warmly about.

LockDown Browser ships an update every 5 weeks, McGraw Hill Express Library every 4 months. Both last shipped on October 26, 2026.
