Facebook spying on you wasn’t enough, now app called “ChatWatch” let’s your friend spy on you too. Currently the app has been taken down from appstore and playstore.
This app let’s people know how many time a person checks the app and when the person goes to sleep and how much he sleeps. If someone is spying 2 numbers, it can also tell when those two talk to each other.
The app has $2 subscription fee you have to pay per week for spying on two contacts, you can spy on up to ten contacts if you pay more. If WhatsApp is your messenger of choice then hope your friends aren’t using this app to spy on you.
