I spent a long time deciding on a monitoring app. They all had inconsistent reviews. I went with Highster based on how long they've been around and the one time payment. They charge you double right out the door for a product that bares no resemblance to what is advertised. My only advice to wary parents who find themselves in a quandary about selecting a legitimate monitoring app is to call the customer support line of the prospective company first. Base your decision on how bad you get the run-around. I wish I could recommend more.
