iOS 8 Health app

You'll need a third party app to send that data to Health.

I believe the FitBit app plugs into Health for calorie counting.

An app like Pillow or Sleep Cycle plug into Health for sleep activity.

OK thank you

FitBIt seems awesome but I've not seen into this app if it works with Health, does it?

And I'll going to download Sleep Better for my sleep activity

No, FitBit does not work with Health. Their CEO has specifically state they will not support HealthKit. However, there are some apps such as SyncSolver that will allow you to move data from the FitBit app to Health. There are some very inexpensive tracker options that play nice with Health available from Shine (Misfit Flash) and from Jawbone.

SyncSolver transfers data from the FitBit app to health. You'd need both. If you're looking for an app (and not a wearable) for your phone, look at Moves, Jawbone UP app (the one that doesn't require a band).

yes but Jawbone UP isn't optimized for iPhone 6/6 Plus.

🙂

That would seem to be one of the least important attributes. It looks fine. And, more importantly, it works well. In fact, of all the apps of it's type, it's my favorite.
