FlexiSPY is one of the most feature-rich and powerful cell phone spy software I’ve tested. It’s one of the very few spy apps to offer something called Call Interception, which lets you secretly record and listen into phone calls. The only catch is that you’ll have to root or jailbreak the target phone in order to install it.
If you’ve jailbroken their iPhone, or rooted their Android phone, you can take advantage of the FlexiSPY spy app. Once installed and configured, it runs in the background and silently records all user activity, including call recordings, call history, GPS, texts, emails, photos, social media and instant messages (Facebook, WhatsApp, Skype, etc.), and more. All the data collected can be viewed through a web-based portal or mobile app.
FlexiSPY has been around since 2006, and it’s still a popular spy app today. There are two versions: Premium and Extreme. FlexiSPY Premium offers everything you generally need from a phone spy app, but if you want more advanced features, the Extreme version might be what you need.
