# Context vs Readex

The clearest difference is review sentiment: Readex at 100% against Context's 58%. Readex also leads on rating (5.0 vs 4.5) and update cadence (every 2 days vs every 6 days). On price, ratings volume, ads and in-app purchases there is nothing between them.

Both are free to download. Context sells 2 in-app purchases, starting at $9.99 per month and Readex sells 3 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.
