# Sleep Cycle vs NapBot

The clearest difference is rating: Sleep Cycle at 4.7 against NapBot's 4.2. Sleep Cycle also leads on review sentiment (40% vs 21%) and chart position (#39 vs unranked). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Sleep Cycle sells 9 in-app purchases, starting at $2.99 per month and NapBot sells 2 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

Sleep Cycle holds the better App Store score, 4.7 against 4.2. That said, the two scores are not equally well evidenced: Sleep Cycle has 32K ratings behind it against 6.3K, so its average is the more settled of the two. Written reviews point the same way: 40% of Sleep Cycle's written reviews are positive against 21% of NapBot's.

Sleep Cycle ships an update weekly, NapBot every 11 days. The most recent releases landed on November 9, 2026 and November 6, 2026 respectively.
