# Master English vs RAIO App

The clearest difference is review sentiment: Master English at 79% against RAIO App's 20%. Master English also leads on rating (4.9 vs 2.7) and ratings volume (32K vs 43). RAIO App's advantage is monetization model (free with in-app purchases vs subscription). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Master English sells 1 in-app purchase, starting at $13.99 per month and RAIO App sells 2 in-app purchases, starting at $19.99 per month. Whichever you choose, the download price is not the number that matters.
