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 youre in. And if you have an Apple Watch, you can unlock your Mac right from your wrist.

Using Knock wont drain your iPhones 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.

BEFORE PURCHASING KNOCK, PLEASE CHECK THAT YOUR MAC IS COMPATIBLE IN THE SCREENSHOT BELOW.

誤動作多し、買う価値なし

応答速度が遅く、アプリの反応を待つ間にパスワードを入力できる。誤動作が多く、アプリが全く反応しない、スリープ時に暗転したまま復帰しないなど致命的な問題がある。スリープ時に暗転したままで困っているユーザーはSMCリセット、PRAMクリアでもなく、このアプリをアンインストールするべし。

Freezes my Mac

This app simply does not deliver. It slows down the login time and works only sometimes. It froze my Mac...

Love this app!

Works as described. In my pocket, on my desk. I followed the instructions and set it up and with the app always running (doesnt consume much power) it works flawlessly!

Did not work for me

Im not a newbie. Ive used macs since 1980. This app just doesnt work. My MacBook Air gets locked on the password screen of the app and its over . I can knock on my phone with a hydraulic hammer and my Mac still needs the password. For my Mac Pro 2013 same deal. Something is wrong. I wasted $5 , then again trial and error. Ill wait for Apple solution with the fingerprint.

Application has to be open on the phone!

Does not work if the phone is asleep or locked. Application has to be open and running. Do not buy if you want this for phone only. I do not have a watch

Just wait for Apple to add this function...

I tried this product 2 or 3 years ago. It was a cool idea, but it did not work anyting like I needed it to or like it says it did. Plus I did not want to be knocking on my iPhone screen. Fast forward a few years later... I heard about this app again on a Applebyte. I throught, "well if it is still around it they must have fixed the issues that they had with it when I tried it years ago". NOPE! It still does not do what they show it can do in the video on the webpage and when my computter has been asleep for a while, it will show a cool color ring around my picture at login, but it wont do anything. I open the app on the phone and nothing I restart the app and.... thats right nothing. It just does not work. I heard that Apple was working on a similar function for the next MacOS. Just wait! Even the idea of Apple possibly working on a similar function is better than this app which already exist. I wasted a lot of time with Knoc, on more than one occasion and now I have to say "please do not even waste your time with this". Great idea, but horible execution.

Pas très utile, mais très fun !

Les soucis ? Devoir garder lappli active sur liPhone, ainsi que le Bluetooth. Mais Knock est vraiment cool, rapide, et efficace (tout en nétant, bien sûr, quun gadget).
