HealthKit is losing people's data

Side note: I talked to an Apple developer at WWDC and was told that HealthKit data never leaves the device (isn't synced with iCloud). Hence the lack of the iPad app. Given that, if the data is lost, its probably gone forever.

The problem with HealthKit is the lack of testing. Developers may have had the beta app for months - but it couldn't do anything. The app relies (mostly) on data from third party apps and due to the beta testing limitations (100 devices) people running iOS 8 betas couldn't install HealthKit beta apps and test them with the HealthKit app. Same things applies to keyboards which I've found to be very buggy and I think most of it is on the OS side not the keyboard app side. Hopefully this won't be as big of an issue next year with the new TestFlight service (1000 users limitation).

I&#x27;ve seen this problem and I think what&#x27;s going on is that the service that&#x27;s keeping the data is having problems catching up.<p>I noticed yesterday that the data was missing. But it reappeared later (though the dashboard was missing). When checking the data manually (getting to somewhere that has data, like Walking + Running distance) and trying to get all the data, it seems to try to load data, but doesn&#x27;t get it (spinning wheel)<p>Given that the data was available later the same day, I&#x27;m guessing that the problem is related to services that are not as available as they should, probably due scale after all the devices using iOS 8.<p>This is all speculation, of course.

I&#x27;ve had this happen a few times (iPhone 6, iOS8.0.2), but I&#x27;ve found that powering off my phone and restarting seems to restore the data. None of it is truly gone for me, it remains logged and listed, but it&#x27;s almost like it cannot access the database of data that&#x27;s stored and it gets a bit wonky but I&#x27;m not certain on that. Hopefully Apple will have it fixed for the next version or the app will be dead in the water.

I am curious if it is related to just iPhone6 models or if anyone is noticing it on the older models. I have an iPhone5s and have had no problems so far.

The headline should read &quot;Anyones health kit app stop working?&quot;<p><a href="https://news.ycombinator.com/newsguidelines.html" rel="nofollow">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;newsguidelines.html</a><p>My dashboard only contains a few things I entered manually, and fortunately it&#x27;s still there. I haven&#x27;t been using a 3rd party app, yet. (iPhone 6 w&#x2F; 8.0.2)

The step data is surprisingly fine grained. I will get 5-10 data points per minute, just walking around the house. So while it seems like a basic thing, it&#x27;s probably the most data by volume that HealthKit is tracking.

I found this thread because the same thing is happening to me. I wonder how wide-spread this actually is.
