While there are a lot of uses for the app – from spying on the activity of a spouse/partner, to seeing who your kids have been chatting with. Granted it’s not as effective as monitoring what’s happening on screen, it’s better than nothing. Plus it reveals passwords, if you’re that kind of person. Not saying that we believe it’s the right thing to do, it’s just that there are so many different ways to make use of this app. Since previous apps that performed similar tasks have been removed from the App Store before, we don’t know how long this one will stay up, so get it while it’s still available. SpyKey is $4.99 on the Apple App Store.
