Knock and Apple Watch: a match made in heaven. Knock 2.0 makes unlocking your Mac faster and more secure than ever.
You keep your iPhone with you all the time. Now you can use it as a password. You never even have to open the app— just knock on your phone twice, even when it’s in your pocket, and you're in. And if you have an Apple Watch, you can unlock your Mac right from your wrist.
Using Knock won't drain your iPhone's battery, even if you use it all day every day. Knock securely communicates with your Mac using Bluetooth Low Energy, a new technology that draws very little power.

Ratings and Reviews
Was great when it was released but it does not work with recent Mac or Watch OS, has not been updated in 3 years so don’t expect it ever will.
I was charged $6.47 without giving permission. The app doesn’t even open or function. This is a total scam.
Don’t buy this app
So I bought the app but I can’t use it cause it doesn’t support High Serra yet which it should!!!! What a waste of 5.99
