# Decoding Chart vs English Grammar

The clearest difference is rating: English Grammar at 4.6 against Decoding Chart's 4.0. English Grammar also leads on update cadence (weekly vs every 36 months) and ratings volume (51 vs 2). Decoding Chart's advantage is in-app purchases (none vs 10) and ads (none vs shown). On price, review sentiment and iOS requirement there is nothing between them.

Both are free to download. English Grammar sells 6 in-app purchases, starting at $8.49 per 7 days. Decoding Chart asks for nothing beyond the download.

English Grammar holds the better App Store score, 4.6 against 4.0. That said, the two scores are not equally well evidenced: English Grammar has 51 ratings behind it against 2, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.

Decoding Chart ships an update every 36 months, English Grammar weekly. The most recent releases landed on November 1, 2026 and November 2, 2026 respectively.
