Health app lost data after updating to 8.02

Same here. This is really not a good apple

I had a similar issue (iPhone 6). Eg I ran 3 miles yesterday, and the health app shows no distance for yesterday in the charts, but it did yesterday before the 8.0.2 update. My steps and flights climbed are both accurate though.

Yep, same thing happened to me (and a few people on MacRumors are reporting same). I came here hoping to find a solution, maybe a way to restore my lost steps. If I can't trust the Health app to save my activity data after a routine software update, it's useless. I was about to ditch my fitbit since the M8 + Health can do the same thing, but even the free fitbit app backs data up to a remote server, which Health apparently doesn't. Hmm, if only Apple had some kind of cloud backup system in place to help with this... An "iCloud," if you will. Dare to dream!

After I updated to iOS 8.0.2 I began entering all my data and even syncing with the updated MyFitnessPal app and everything seemed to be working fine. I had multiple dashboards including the blood glucose one so that I could see trends in my readings. Everything worked fine until later that night, 9-26-2014, when all my dashboards were gone from the main screen. I went into each separate health data category and all my data is gone. Now if I even try to click on the "me" category the app just freezes. It would have been nice if all that data was backed up on iCloud and I could restore, but I can't.

Using an iPhone 5s 16GB on iOS 8.0.2.

I am also having this problem. My dashboard was reset this morning and I tried to re-add my various data points to it. The switches toggle, but the dashboard remains blank and all my data seems to be gone.

That is exactly what is happening to me. I have tried to turn off the read and write data to the Health app for MyFitnessPal and turn them back on and nothing happens, it's like the Health app is just frozen.

Me too. health app freezes in 'Me' and dashboards aren't working. Healthkit is working, various apps are sharing data, but the one feature I was looking forward to isn't. Try reinstalling all apps, hard reset...nada.

Way to go Apple! I just checked the app again and all my dashboards and data are back. Apparently somehow the data must be backed up because I didn't restore anything, restart my phone, or delete any apps.

Okay, so the only HealthKit app I had installed was MyFitnessPal. I deleted it and did a hard reset (home+sleep) and my dashboard & data is back. Are all you guys using MFP? Maybe it's a MFP bug?

Either way, try the hard reset.

I thought I was the only one. Started having the same problem after the 8.0.2 update. I also use MyFitnessPal (MFP). I've noticed using the M7 processor still logs activity in MFP, but not in HealthKit. In fact my selected health readings disappeared and every time I shut down the app, I lose them again.

There is definitely a problem with HealthKit.

I am not using MFP, but rather RunMeter, which accesses pedometer data.

Today I did a bunch of walking/running, and health app says I did 50 steps. Run meter says something like 15,000 which is what I would expect. Seems like apps that access health data appear to hijack the data completely or something.

I'm not sure what Apple felt like they needed to address in HealthKit that they pushed out 8.0.1, but it was working prior to 8.0.2.

I wasn't using any other apps, I was just tracking my steps with the health app itself (and comparing it to my fitbit -- side-note, they were always within a few hundred steps of each other). I just tried the hard restart trick and it didn't restore my pre-update step data. Unlike others have reported here, it seems to be working fine since the update, just wish it hadn't wiped out my first week of steps (I'm on a 64 GB iphone 6 VZN btw).

IIf health app dashboard is showing empty, but data is present within each sub screen, try switching off phone and back on. It seems to wok for me.

i Think it's an ios 8.02 bug

I'm having the same issue. I tried hard reset/and plain old restarting phone. It tracks nothing! Not to mention extremely poor battery life now
