iOS 18 update and Missing Health/Fitness Data

I recently bought the new iPhone 16 Pro Max and unpaired my Apple Watch Ultra from my old iPhone 14 Pro Max. Everything works perfectly—my Apple Watch Ultra collects data like calories, ECG, breathing, etc. However, in the Health and Fitness apps on my iPhone 16 Pro Max, I only see data from the last day of migration. Oddly enough, everything else like music, messages, and Siri works fine. I’ve tried calibration and location settings, but nothing helps. I don’t want to reset as I might lose data. Any suggestions?

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

Sleep Tracking is still available, the oxygen function used to track apnea is not, for models sold in the US after January 18, 2024. It was Apple response to a 3rd party claim of a proprietary interest in that function.

The only good healthy feature I used for years, now you removed it? For what? Make more money to buy a watch?! Maybe I won’t update iOS anymore and buy other brand cell phone in the future and remove iPhone totally!

Apple told me that the Health app has never been able to track sleep duration, unless we have an Apple Watch.

This cannot be true. My iPhone XS Max has been tracking sleep duration unless duration for years. And I do not own a watch or a 3rd-party sleep app. This is frustrating.

So….it seems you have to set a wake up alarm!!!! WHO in their infinite wisdom thought this was a good idea? I never use an alarm as it wakes my wife up as well, never a good idea.

It seems you cannot write what you think here for fear of upsetting some. Original post edited to omit the following 🤷‍♂️

“That’s this in the bin then - HATE alarms. Too jarring. Will it be fixed?? Or does ideology win the day again?”

this isn’t offensive, it’s a question. Did I hit a nerve??

The activity tracking on my watch SE is not syncing with the fitness App on my iPhone 16. I am also still running my iPhone 13 Pro in parallel until I am certain all passwords are correctly set, and the apps are available.

It would have been nice to leave the toggle option to record the data or not. Not everyone can afford nearly 1k for a watch. The fact that Apple just removes the option for those disadvantaged shows the lack of respect and consideration for their buyers. I mean face it, if it wasn’t for the buyers, they wouldn’t have their billions.

It’s a health related feature. Don’t remove it, try and improve it.

I’m in need of an upgrade but given that feature removal, I’m going to go with a different brand.

Noticed too that my sleep time is no longer logged on my iPhone after updating to iOS 18. I could still add data manually, but it’s too cumbersome to do. I figured the feature must have been removed because it’s usually inaccurate sans a Watch

Side question: I moved from an iPhone 13 Pro to a 16Pro. Luckily, I could keep my phone and still get the trade-in credit. But my watch was paired with the 13 Pro. What would have happened if I had turned the phone in and it was wiped? Would the pairing with the iPhone 13 Pro leave it stuck in limbo? Could I still unpair the watch even though I no longer had the device it was paired with?

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
