I’ve been using the Ring Doorbell Pro for the past couple of years. It has been a great camera/doorbell with very few issues. Ring recently released a new app for iOS and Android that allows quick access to view the camera. It is called Rapid Ring. The original Ring app is great for video playback and changing settings but at times it is so slow the person ringing your door may have already left. Rapid Ring quickly loads the video feed of any Ring device. If you are experiencing slowness with the current Ring app, I recommend trying Rapid Ring App.
