iOS 18 update and Missing Health/Fitness Data

Good morning everyone!


I’ve been having one heck of a week with my iPhone and Apple Watch. First my phone was acting up, so I restored from my iCloud backup to iOS 17.6. Everything is going hunky dory, Health and Fitness are slowwwwwly redownloading my rings, awards, all my recorded. Great? Great. Then I downloaded iOS to my phone, and that’s when all the problems started. Here’s where things get interesting:



  1. After the iOS 18 the Fitness and Health apps refused to record my calories, steps, stand hours.
  2. At one point, my watch managed to unpair itself from my phone.
  3. All my rings, awards, EVERYTHING going back to 2013 is gone!
  4. The Fitness and Health apps seemed to be trying to redownload something, but would get stuck at a certain point.
  5. There’s no listed monthly challenge in Fitness.


I’ve called Apple about this and was told this is a known bug. I was instructed to delete the health data off my phone to force downloading from iCloud. But it just doesn’t seem to be doing it, as far as I can tell. I’ve attached screenshots of what I’m seeing. There’s a little over 17gb of data on iCloud which corresponds with all my Health and Fitness data. Is there anything I can do to resolve this?

Earlier I use to track my sleep data with my iphone only ( Without Apple Watch ) but after updating it to IOS 18, Sleep widget not tracking my sleep , I have tried everything but still the same issue ( No data Available )

Hope apple resolve this in upcoming updates.

Same here. Reset everything, unpaired and re-paired watch and still nothing. Oh, my mistake it says I was in bed for 3mins. Come on Apple you have only your eco system to work with. What happened to “it just works”.


Vitals! Luckily it isn’t vital I have it working. Maybe time to move to Ultrahuman or Oura because this is a joke. £2k on hardware that just doesn’t work and software rushed out

After I installed iOS 18 the Trends data no longer populates. I can still see fitness data back to 2019 but the Trends area never populates. Apple Help Desk suggested unpairing watch then deleting and reinstalling the Apple Fitness App. I have not tried this yet as I’m worried about losing everything. I’ve been watching for a software patch ?

The option of using an alarm doesn’t work consistently. Sometimes the sleep and vitals populates and sometimes it’s just those block of blue squares and nothing populates. Vitals sometimes takes 1 reading sometimes 5 - it’s a hot mess of rushed software release.

somehow though Welltory seems to be able to capture sleep stages and populate it correctly. Come on Apple you only have your hardware and software to work with so please get back to the moto of “it just works”. As of now it’s just an expensive lack lustre experience

Unfortunately I’ve tried that and it still doesn’t do as advertised. It recorded nothing last night. Not even a little blue block and only 1 vital. Just ordered whoop to see if that’s better and then onto ours if not. At present it’s an expensive hunk of junk good for naff all! Said to Apple yesterday I may want a full refund due to it not being fit for purpose, which it isn’t
