# Sleep Time vs Sleep++

The clearest difference is rating: Sleep Time at 4.7 against Sleep++'s 4.1. Sleep Time also leads on review sentiment (76% vs 39%) and update cadence (monthly vs every 2 months). On price, ratings volume, ads and in-app purchases there is nothing between them.

Both are free to download. Sleep Time sells 8 in-app purchases, starting at $4.99 per month and Sleep++ sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
