The Curt Echo Mobile Trailer Brake Controller part # C51180 will work with both iPhones and iPads. That said, these devices will need to have an IOS of 8.0 or newer. Since you said your iPhone 4S has an IOS of 9.3.6 it will work just fine with the Curt Echo. The last I checked, the iPhone 4s is the oldest iPhone that can be used with the Curt Echo so you are in luck.

The ECHO Smart Control App requires 7.2 MB of space for installation as of August 2019.
