Use your Apple Watch to AUTOMATICALLY track your sleep! Sleep++ takes advantage of the motion and health monitoring capabilities of your Apple Watch to measure both the duration and quality of your sleep. The better you understand how well you are sleeping the more you are able to make changes in your routines to benefit your rest. My goal is to provide every Apple Watch owner with a free automatic sleep tracker that is simple and clear to understand. For each night you get a straightforward report of how long you slept and how restful you were during the night. AUTOMATIC MODE: Simply wear your Apple Watch overnight and each morning Sleep++ will analyze your sleep and give you a report about how long and restfully you slept. MANUAL MODE: If you want to have more precise control over the start/end time of each night recorded you can also use manual sleep tracking. This is also useful if your nightly routine makes it difficult for Sleep++ to determine when you went to bed. 1) Wear your Apple Watch while you sleep. 2) Tell Sleep++ when you start sleeping. 3) Tell Sleep++ when you wake up. NOTES: Sleep++ integrates with the Health App providing you a safe and private way to share your activity data with Sleep++. This data is used for automatic sleep tracking. You can also optionally have Sleep++ save your Sleep Analysis into your Health database after each night.

Verdict

The call

The clearest difference is ads: Pillow at none against Sleep++'s shown. Pillow also leads on update cadence (every 11 days vs every 2 months) and rating (4.4 vs 4.1). Sleep++'s advantage is iOS requirement (15.0 vs 17.0). On price, review sentiment, in-app purchases and monetization model there is nothing between them.

CostPrice · In-app purchases · Ads · Monetization

Both are free to download. Pillow sells 6 in-app purchases, starting at $19.99 per month and Sleep++ sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Pillow holds the better App Store score, 4.4 against 4.1. That said, the two scores are not equally well evidenced: Pillow has 96K ratings behind it against 5.7K, so its average is the more settled of the two.

UpkeepUpdate frequency

Pillow ships an update every 11 days, Sleep++ every 2 months. Both last shipped on September 24, 2026.
