# Sleep++ vs SleepOn

The clearest difference is rating: Sleep++ at 4.1 against SleepOn's 3.0. Sleep++ also leads on ratings volume (5.7K vs 181) and review sentiment (39% vs 21%). SleepOn's advantage is in-app purchases (none vs 1) and ads (none vs shown). On price and device support there is nothing between them.

Both are free to download. Sleep++ sells 1 one-off in-app purchase. SleepOn asks for nothing beyond the download.
