View iOS Health data externally

Is there a way to view ios 8 health data externally? For example, with iCloud sync it seems feasible to be able to access the data through a website (i've checked https://www.icloud.com/ but it's not visible). I really like the Health app dashboard but I'd like it more if I could also see it from other devices :)

If there is no official way, does Apple allow accessing iCloud data through some web API? I can build a proof-of-concept dashboard if they have some kind of web service.

Lastly, another method I've considered is building an app that (after requesting permissions) reads the data through HealthKit and then provides that to an external storage service. I'd like to know if something like this exists (so I don't reinvent the wheel).

I found another thread from June 2014 that indicates it's not possible to directly inspect iCloud backups, though I'm pretty sure they're only referring to viewing through iTunes or iCloud.com.

Best way I found was to: Open Health App and head to Health data < All and use the arrow on the upper right of the screen then choose Export.

It will take a while if you have a data. You'll be able to get a ZIP file that you can mail to yourself.

Just use XCode and you should (at least!) be able to read your data. You could then use dropbox to sync it with your other devices.

Doing an encrypted backup on iTunes (unencrypted backups don't include health datas) and using a backup reader app, like iBackupbot (http://download.cnet.com/iBackupBot/3000-18553_4-75532275.html), that will ask you your backup password, you can get on your computer the healthdata folder which contains all your Health datas!
