# MMK vs Language Reactor

The clearest difference is in-app purchases: MMK at none against Language Reactor's 13. MMK also leads on review sentiment (98% vs 66%). Language Reactor's advantage is ads (none vs shown) and update cadence (every 3 weeks vs every 7 months). On price, rating, device support and iOS requirement there is nothing between them.

Both are free to download. Language Reactor sells 12 in-app purchases, starting at $3.49 per month. MMK asks for nothing beyond the download.

MMK holds the better App Store score, 5.0 against 4.8.
