# Sleep Cycle vs Sleep++

The clearest difference is rating: Sleep Cycle at 4.7 against Sleep++'s 4.1. Sleep Cycle also leads on ads (none vs shown) and update cadence (weekly vs every 2 months). On price, review sentiment, in-app purchases and monetization model there is nothing between them.

Both are free to download. Sleep Cycle sells 9 in-app purchases, starting at $2.99 per month and Sleep++ sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Sleep Cycle holds the better App Store score, 4.7 against 4.1. That said, the two scores are not equally well evidenced: Sleep Cycle has 29K ratings behind it against 5.7K, so its average is the more settled of the two. Written reviews split almost evenly too, at 39% and 39% positive.

Sleep Cycle ships an update weekly, Sleep++ every 2 months. The most recent releases landed on September 25, 2026 and September 24, 2026 respectively.
