# iAudio vs Master

The clearest difference is in-app purchases: Master at none against iAudio's 11. iAudio's advantage is ads (none vs shown) and ratings volume (10 vs 2). On price, rating, review sentiment and device support there is nothing between them.

Both are free to download. iAudio sells 11 in-app purchases, starting at $4.99 per month. Master asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 5.0 for iAudio against 5.0 for Master. That said, the two scores are not equally well evidenced: iAudio has 10 ratings behind it against 2, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.
