# Grammar vs Passive Voice Master

The clearest difference is in-app purchases: Passive Voice Master at none against Grammar's 1. Passive Voice Master also leads on iOS requirement (13.0 vs 15.0). Grammar's advantage is ads (none vs shown) and update cadence (every 13 months vs every 80 months). On price and device support there is nothing between them.

Both are free to download. Grammar sells 1 one-off in-app purchase. Passive Voice Master asks for nothing beyond the download.

Grammar ships an update every 13 months, Passive Voice Master every 80 months. The most recent releases landed on October 15, 2026 and October 12, 2026 respectively.
