# Readability vs Read Not Guess

The clearest difference is review sentiment: Read Not Guess at 100% against Readability's 55%. Read Not Guess also leads on monetization model (free with in-app purchases vs subscription) and rating (5.0 vs 4.6). Readability's advantage is ads (none vs shown) and ratings volume (25K vs 7). On price, in-app purchases, device support and iOS requirement there is nothing between them.

Both are free to download. Readability sells 2 in-app purchases, starting at $19.99 per month and Read Not Guess sells 2 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.

That said, the two scores are not equally well evidenced: Readability has 25K ratings behind it against 7, so its average is the more settled of the two.
