For a long away I was looking for a solution to track my cheating spouse's device in order to know who she's talking to late hours in my absence. I tried tons of monitoring apps but didn't find that worked for me. All were asking for access to the cell phone. But one of my friends suggested Spymaster Pro. It's really great software and did a great job for me! I am able to keep track of my cheating spouse's cell phone without having access to her device. It doesn't ask for any access and works without showing an app icon. The totally worthy choice I've made. Highly recommended!
