Based on my experience, I would not recommend this application to any parent looking for a reliable parental control solution.
The free version worked very well, which is why I decided to purchase the Premium subscription. However, since upgrading, almost none of the advertised features work as expected. I cannot remotely turn the phones or tablet off, I cannot see any activity, and the location feature does not work at all. I paid for the Premium version expecting better functionality, but instead it has been a complete waste of money.
