Home app has not been that useful to me even though I only have Philips Hue lights in three rooms. I did download Controller for HomeKit (3rd party app) but never used it. Maybe the new Home app will be easier for me to use.

It's nice that Fitness app will now be on iPhone. Also all the Fitness and Health features are neat and I can see why an Apple Watch would be nice to have.
