Trackidz - With this program, you don't see specific content from your kid's device, but you can track app installations and use, block browsers and apps, manage time in apps and on the device, block out device-free time, grant bonus time, track location, get an alert when your kid's phone is turned off, and see your kid's contacts. It also claims to detect cyberbullying by tracking when your kid's device use drops dramatically, which can indicate avoidance. Setting up a geo-fence lets parents track a kid's location and alerts them when a kid has gone outside the boundaries, and a kid can tap the power button to send an emergency message to parents (currently free, but will be $6.99).
