I just purchased Knock to Unlock. Comments so far;

Locking the Mac requires me to go to the Knock menu bar and clicking "Lock" with my mouse. I suppose this can be remedied by setting up an applescript shortcut and running it quickly via Spotlight Search.

Secondly, when it locks it - the screen goes black. I don't necessarily want this, as I don't want to "wake up" the computer when I return first using my keyboard. It takes a split second or so before I get to the password prompt (I have to tap a key on the keyboard or move the mouse) at which point I can knock on the phone twice to get in.

Thirdly, this is not the fault of the app - but I can type my 8 character long password faster than I'm able to (on average) locate my phone and tap it twice.

Interesting - but I am not sure if I'll end up using this app.

I also tried Near Lock - seems it's a much better option for me.
