Our verdict on Sleep++
Sleep++ is an Apple Watch sleep-tracking app for people who want to review sleep duration, quality, stages, and related health metrics on an iPhone. It supports both automatic tracking from Apple Watch and Apple Health data and manual tracking through the watch app, where users mark when they go to bed and wake up. That makes it a fit for people who want sleep information tied closely to their Apple Watch rather than a general-purpose sleep platform.
The app’s core view combines sleep-stage charts for REM, core, and deep sleep with charts for heart rate, respiratory rate, and blood-oxygen levels. A Readiness Score draws on sleep and heart rate, while a nightly sleep goal and adjustable recorded sleep times offer ways to review or refine the record. Sleep data can optionally be saved to Apple Health or exported. This is a useful concentration of sleep and readiness information for Apple Watch owners, though the described feature set stays centered on sleep tracking rather than a broad health or coaching toolkit.
Sleep++ is freemium, with a free plan. The App Store lists a $1.99 in-app purchase called Support Development; it is not described as a paid subscription plan or as unlocking additional features. Apple Health is the named integration, so buyers seeking a wider integration ecosystem should compare alternatives. Choose Sleep++ if free Apple Watch tracking, sleep stages, readiness data, and Apple Health write-back or export match your priorities. Look elsewhere if you need broader platform coverage or a more expansive set of verified extras.
