Absolute garbage. My daughter gets to school at approximately 8:50am. My phone doesn't alert me that she arrived until almost 10am. Yesterday, I was informed, via the app, that my child left school. I was unhappy, thinking that she was skipping class. I jumped her case! Then, I received a pic from her, sitting in class! It RARELY ever lets me know when she leaves the house. It RARELY ever lets me know when she gets home. This app is WORTHLESS! in the time it take to receive the DELAYED notification, she could have been kidnapped, and 50 miles away. What a waste of money. And, yes. The newest version is on both phones. This is NOT a reliable app.
