# iRis vs Sleep

The clearest difference is in-app purchases: iRis at none against Sleep's 12. iRis also leads on ads (none vs shown) and review sentiment (75% vs 60%). Sleep's advantage is ratings volume (9.6K vs 10). On price, rating and device support there is nothing between them.

Both are free to download. Sleep sells 12 in-app purchases, starting at $2.99 per 7 days. iRis asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 4.3 for iRis against 4.3 for Sleep. That said, the two scores are not equally well evidenced: Sleep has 9.6K ratings behind it against 10, so its average is the more settled of the two. Written reviews are what separate them: 75% of iRis's written reviews are positive against 60% of Sleep's.
