The world of jailbreaking is extremely diverse. Not only it lets you do things on your device which Apple has not sanctioned, but it lets youadd stuff which the companytotally missed out from its firmware. For example, if you have a hunch that someone might be using your iPhone while you are away, there's no telling at all if that's the case. Furthermore, if your phone gets stolen, there's no measure putin place that allows you to snap a photo of the thief or go through other crucial information on your device remotely.
That's where a wonderful little tweak called OwnSpy comes in.
Recently updated to support theiOS 10 jailbreak, the tweak lets you snoop in on your own device. It lets you do a bunch of things from the get-go such as recording the calls being made from the device, go through photos in the gallery, check deleted SMS or WhatsApp and more.Basically, it's a jailbreak tweak that lets you take full control of your device when you are not around. Last but not the least, you can even backup your stuff remotely using the tweak, which is quite handy.
Interestingly, the tweak is available to try for free for those who are interested. Once you have made up your mind, you have to pony up a little money to get the full, unlocked experience.
At this point you must be thinking - why shouldn't I install this tweak on someone else's iPhone?

So, before you even think about doing such a thing - just don't. It's a bad idea, and we completely discourage such acts.
