# Grammar Express vs Medical Reference Guides

Medical Reference Guides's advantage is update cadence (every 9 months vs every 149 months) and iOS requirement (12.0 vs 15.0). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Grammar Express sells 1 one-off in-app purchase and Medical Reference Guides sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Grammar Express ships an update every 149 months, Medical Reference Guides every 9 months. The most recent releases landed on September 25, 2026 and September 17, 2026 respectively.
