What's New in Sleep Details

6.0

September 11, 2026

This update focuses on new features for iOS 27 and watchOS 27 — smarter summaries on iPhone and a new sleep summary on Apple Watch. Smarter summaries on iPhone (iOS 27): Summaries now run through Private Cloud Compute whenever possible, including when browsing past days and in the full Daily Summary sheet. The new short summary on the main screen focuses on the night's most notable facts, reads more naturally, and ends with a practical suggestion — like repeating the bedtime that worked, based on your own recent nights. When Private Cloud Compute isn't available, an improved on-device fallback takes over. AI Sleep Summary on Apple Watch (watchOS 27): Your watch now generates the same short AI sleep summary as the iPhone, privately via Apple's Private Cloud Compute. It lives on its own page between the main screen and the details list: swipe to it, or tap the score gauge on the main screen.

Too basic

The data being tracked is very limited and no description of why your overall score is rated as it is. You can’t export the data so I’m not sure what I’m supposed to do with data captured in a single app that I can’t analyze. Also, it greatly varies to sleep scores as reported by Apple and when I get a low rating, I actually don’t feel terrible so I don’t trust it’s algorithm.

Bye

Claims a free trial, the sole way to test features. But Apple’s popup lacks “free” language ALWAYS appearing in every other circumstance a free trial is actually on the table. If you’re not paying attention, you’ll get snickered. Deleted, with dev added to my NEVER! List.

Recent update or what?

Honestly I loved using this app for months now. It kept me on top of my sleep and I loved the fact it would score it.
Recently, idk if it was an update or what but I can’t even add my supplemental sleep anymore.
Because I take naps here and there or sleep past alarm lol. But it won’t even allow me to add them anymore. So I’ll be just going back to apple health because at least there I can add it.
