I believe the scrolling physics can be updated. In the Bonus Points section they mention: > Also, you may notice a difference in the scrolling deceleration time between the native iOS app and Fastbook. In the native app, scrolling doesn't stop for about 3s. We decided to increase friction and reduce the animation duration to 1.4s. This not only makes content ready to read faster, it also provides extra idle time for the app to buffer more items while the user is still reading existing content.
