These actuator controller mobile apps for DC motors can independently control four actuators in different combinations. Here are some of the features:

1. Works with all Progressive Automations or any other brands of linear actuators or DC motors
2. Control up to four actuators through Wi-Fi (individual, simultaneous or any other combination)
3. Directional control for each actuator
4. Set a time delay of up to 999 seconds on one, two, three or four actuators
5. Choose from momentary and non-momentary settings
6. Group linear actuators together for multiple actuator control

This is an example of how mobile devices can control hardware and mechanical machines.
