# BitSafe vs Grammar

The clearest difference is price: Grammar at Free against BitSafe's $4.99. Grammar also leads on update cadence (every 2 weeks vs every 4 months) and ratings volume (1.1K vs 2). BitSafe's advantage is rating (5.0 vs 4.4) and in-app purchases (none vs 1). On device support there is nothing between them.

Grammar is free to download; BitSafe costs $4.99 up front. Grammar sells 1 in-app purchase, starting at $4.99 per 7 days. BitSafe asks for nothing beyond the download.

BitSafe holds the better App Store score, 5.0 against 4.4. That said, the two scores are not equally well evidenced: Grammar has 1.1K ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 100% of BitSafe's written reviews are positive against 70% of Grammar's.

BitSafe ships an update every 4 months, Grammar every 2 weeks. The most recent releases landed on November 1, 2026 and November 3, 2026 respectively.
