How to Catch a Cheater: 10 Best Cell Phone Spy Apps Online for Free

The most convenient, hassle-free way to monitor their phone is with a cell phone spy app. In this article, we offer 10 of the best cell phone spy apps in town. We picked them based on their stealth, reliability, and feature-set. 

Part 1: How to Catch a Cheater 

You catch a cheater red-handed if you monitor their phone or tablet. If they’re cheating on you with someone, they likely message that person or call them. You just need to read a compromising message or take a look at their call logs. 

The best way to do so – covertly and privately – is with a spy app. We recommend making Spyier your first option. 

1.1 Spyier: The best app to catch a cheater with

a. Spyier gives you complete access to their phone or tablet 

With Spyier, you can see almost everything the potential cheater is doing on their phone or tablet. You’ll have ample opportunity to find proof on their cheating behavior:
