If you are wondering about cell phone spy apps, you should know that there are many of them that you can choose from. However, just like anything else, they are not created equal and there are those that are more highly-rated than others.
If you want to know which ones are considered the best by smartphone users, you should go to the Google Play store and search for “spy app”. You can instantly tell the top apps by their rankings, that is, their place in the search results. However, you should not rely on their rankings.
If you did just that, you will see that the top results are mSpy and two others. Of course, you don’t just content yourself with the rankings. You will want to see how they work in real life. Download one app and see how it works. If that does not work as well as you had hoped, then move on to the next app until you find one that fits your needs best.
Most apps come with a demo version or a free limited version so you do not need to buy anything just to see if an app works.
