  1. Customer support
    Before settling on a specific service provider, be sure to check how easy it is to reach their customer service team. A great way to do this would be by getting in touch with them through the communication channels provided on the official website. Inquire about their products to see how long it takes to get a response.
  2. Online reviews
    The vast majority of company searches begin on Google. Look for reviews and comments from real users to get insight into their experiences using the spyware. If you come across a vast number of negative reviews, it’s probably a good idea to go with a different company altogether.
  3. Check the website for valuable information
    It’s always in your best interest to skim through the terms and conditions of the company, as well as any disclaimer that may not align with what you hope to achieve with the spy app. It also provides an excellent opportunity to review the features of the app and use the live demo to get a feel for it. A company that doesn’t offer this isn’t worth pursuing.
  4. Free trial and money-back guarantee
    A great company should allow its customers to get a feel for the software with no risk of money-loss if it doesn’t live up to their expectations. Always go for the ones that offer free-trials or, at the very least, money-back guarantees if you’re not satisfied with the product.

Is It Illegal to Spy on Someone’s Cell Phone?

No, spying on someone’s cell phone isn’t illegal – for the most part. You can only install spy apps on mobile devices and computers that you own or that your underage kids own. If you want to spy on someone else’s phone without their permission, though, you could get yourself into some legal trouble.

So, if you’re looking to keep a close eye on what your kids get up to, it is well within your rights to install spyware on a device that you bought for them. There’s no specific law that prohibits you from doing this. Children do have a right to privacy, but only to a certain extent.

As a parent, you must keep an eye on them and keep them out of harm’s way. And, if you don’t particularly have an open relationship with them, sometimes a phone spy app is the only way to get to know what’s going on in their lives so that you can keep them safe.

On the flip side, if you’re an employer who wants to keep tabs on their staff members, it is legal to install top cell phone spyware on the company devices. It is, however, illegal to use the apps to monitor them through phones and computers they own without them consenting to it. The same applies to phone surveillance on your spouse or partner. The keyword here is “consent.” Look up your local surveillance laws and see where they stand with regards to spyware.

Will the Person Know That I Am Monitoring Their Phone with a Spy App?

Unless you disclose the fact that you’ve installed a spy app on their phone, you target will never know that you’re monitoring their phone with a spy app.

The best spy apps come with a stealth mode feature, which, when activated, makes them completely undetectable on the target mobile device. It won’t appear in the application list and is designed to be extremely lightweight. So, it has little to no impact on the target device’s overall performance. mSpy, Flexispy, and Cocospy all have this feature.
