# Engo vs KnowLang

The clearest difference is ratings volume: Engo at 119 against KnowLang's 1. Engo also leads on update cadence (every 8 days vs every 3 weeks). KnowLang's advantage is rating (5.0 vs 4.8). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Engo sells 11 in-app purchases, starting at $1.99 per 7 days and KnowLang sells 7 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.
