here is how the top iphone apps are using 3D touch
So many apps have only added Quick Actions (or nothing at all)We covered a number of the best initial 3D Touch uses when the 6S first launched in September.

A lot of big app developers haven't added anything more than home screen shortcuts; that is, the Quick Actions that pop up when you press hard on an app's icon.
