# Polyglot Reader vs Readlang Mobile

Readlang Mobile also leads on review sentiment (100% vs 66%) and update cadence (every 6 days vs every 2 months). Polyglot Reader's advantage is ratings volume (74 vs 3) and iOS requirement (16.0 vs 18.0). On price, rating, in-app purchases and monetization model there is nothing between them.

Both are free to download. Polyglot Reader sells 11 in-app purchases, starting at $3.99 per month and Readlang Mobile sells 2 in-app purchases, starting at $6.99 per month. Whichever you choose, the download price is not the number that matters.
