# Spanish Grammar vs KeyFluent

The clearest difference is rating: KeyFluent at 5.0 against Spanish Grammar's 4.5. KeyFluent also leads on review sentiment (100% vs 88%). Spanish Grammar's advantage is ratings volume (50 vs 5) and iOS requirement (15.1 vs 17.0). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Spanish Grammar sells 12 in-app purchases, starting at $4.99 per 7 days and KeyFluent sells 2 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.

KeyFluent holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: Spanish Grammar has 50 ratings behind it against 5, so its average is the more settled of the two.
