Its pretty good

This app makes it really easy to buy stuff with Apple Pay, but when browsing its really annoying to use 3D Touch because the Taptic Engine lags on my iPhone 7. Ill peak with 3D Touch and itll do the animation, but the vibration is delayed. Also, the app stutters quite a bit, although the entire OS has been stuttering and not as stable since iOS 9.
