Now with the most recent update, it now requires an email. No thanks, so long. ### 3/5 — Buggy but (barely) usable *2026-06-03, version 5.454* I’ve been using this app since 2012 so I have amassed lots of data over the years. Regrettably, Azumio pays very little attention to this app and it hasn’t been updated in a while. [edit 06/02/26]: Azumio completely broke the tag functionality with the latest update. Let’s hope they get it fixed. There is no way to get the sleep data out of the app that I’ve found, even with the Premium version. Supposedly it syncs with the iOS health app but the Health app finds no Sleep Time data to sync so 🤷‍♂️. Also, it’s extremely buggy. Crashes a lot when trying to update tags, etc. I would move to a different sleep tracking app if I could get the data out of this one. ### 5/5 — This Sleep App *2025-04-04, version 5.416* Helps me to know how much sleep I’m actually getting. I do love the soundscapes to help me fall asleep. Makes it easier. ### 3/5 — Buggy but usable *2025-03-06, version 5.416* I’ve been using this app since 2012 so I have amassed lots of data over the years.

Batterie Einstellungen bestätigen dass es an dieser App liegt. ### 5/5 — Great sleep health app *2023-10-07, version 5.416* This app has helped improve my sleep more than any other sleep app ### 3/5 — Heart Rate Integration vanished *2023-09-12, version 5.416* The latest update on 4 Sept 2023 , supposedly just bug fixes, has down graded the functionality and now integration with Heart Rate has gone. After many, many years of using this app, which I have to date found excellent, this loss of function is REALLY annoying. Please can it be fixed? ### 5/5 — Long time *2023-09-11, version 5.416* I started using this app in April of 2014 and have used it almost every weeknight since then. I love the way it wakes me up. I wish I had a way to export all of the data over to my health app though. It only goes back so far. ## Frequently asked questions about Sleep Time+ Cycle Alarm Clock ### What does Sleep Time+ do?
