# ReViiV vs Sleepwizard

The clearest difference is update cadence: Sleepwizard at every 4 days against ReViiV's monthly. Sleepwizard also leads on review sentiment (100% vs 75%). ReViiV's advantage is device support (3 vs 1) and iOS requirement (13.0 vs 26.2). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. ReViiV sells 2 in-app purchases, starting at $0.99 per month and Sleepwizard sells 6 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.
