App-controlled vibrators allow you to control the stimulation of your partner's genitals with your phone. This means that you can turn the vibrations on and off, increase or decrease their intensity of them, and even change the pattern of vibration.

This type of toy is particularly useful if you are separated by great distances from your partner. You can use it as a way to stay connected while they are away from you, but also as a way to enhance your sexual experience with them when they return home.
