# Smart Study Global vs Grammar Check

The clearest difference is rating: Smart Study Global at 5.0 against Grammar Check's 4.5. Smart Study Global also leads on update cadence (every 2 days vs every 2 weeks). Grammar Check's advantage is ratings volume (6 vs 1) and iOS requirement (13.0 vs 15.0). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Smart Study Global sells 3 one-off in-app purchases and Grammar Check sells 3 in-app purchases, starting at $1.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Smart Study Global holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: Grammar Check has 6 ratings behind it against 1, so its average is the more settled of the two.
