Knock – unlock your Mac without a password using your iPhone and Apple Watch App Reviews

Awesome! Tested with iPhone 4S and 5S with MacBook Pro 13" Retina late 2013. With 4s is less sensible and some time you have to punch it, but with 5s is more like a double tap :)

Like the title this app is working good on my iPhone5 and macbookpro retina 13" early 2013!

I think this this is the best app in the store, work perfectly, MUST HAVE!

Excellent app. Works as advertised!

I love this app it works perfectly on my phone and apple watch

Seems like the creators had a good idea but didnt execute with high fidelity. This app barely works on my 6 plus and newest MacBook Pro.

The concept of Knock is great. When I first got it, it worked maybe 60% of the time, but it’s been on downward slope ever since. Now it doesn’t work it all. It has never ever worked from my Apple Watch. I don’t know whether the software has gotten buggy, iOS has gotten more restrictive, or Bluetooth is just too flaky to be reliable. Whatever the cause, Knock never activates at all now. So I’m still entering my password manually and have basically given up on Knock.

4.99 for this? First, you have to wake your MacBook / iMac up, then it will take around 10 seconds to connect through Bluetooth, and only then you can knock twice. It takes me less that a second to enter password. You will feel like an idiot looking at your phone, waiting for connection. By the way. I have iPhone 6 and MacBook 15 retina latest and the greatest. I want my money back!

Everyone. Please read the instructions. Knock works without it your phone being unlocked and the app running. You need to wake your Mac before you can use knock. It is in their instructions. Works just like advertised. Just knock twice on your phone or Apple Watch and it unlocks the mac.

When I first got it just kinda thought as a cool gimmick. But after a day or two it just feels so natural. Truly awesome. Hope for some future improvements including 1. IOS 9 support and Metal Support 2. Ability to set location services to “While Using App”.

I have a password that is long enough to be useful and find Knock a great time saver. Recently I’ve experienced very slow detection of the Knock app when waking the computer. I contacted Knock tech support and am delighted that they reviewed several files from my computer that helped them to track the problem and gave advice that really helps.

This app used to be awesome, but it just doesnt work anymore. I have to break the link, uninstall from both devices and reinstall for it to work for a day. If I turn off my laptop, or if it goes to sleep for an extended period, it wont work.

I paid for Knock when it first came out. It used to work great! Over the last year Ive found it to be far less reliable. Ive tried it with multiple iPhones and multiple Macs, so I know its not a device issue. Im sad the all has gotten worse and not better.

The developer had been very responsive, but after several weeks of fiddling with various settings, un-linking and linking, restarting, etc. I am unable to make this work reliably beyond the first time it connects. Within a short time it stops working and I have to restart it, unlink, link, etc. Its just not worth it. I just grabbed MacID and am hopeful it will be more reliable. None of the reviewer complaints Ive seen (much too late) here.

It is a nice concept and nice to have when it works, but it loses sync with my MacBook Pro a lot. To get it to resync, I end up having to put my phone in tether mode and then turn tether back off. This would get 5 stars if it did not keep losing its connection.

The connection is not stable at all

When i purchased the app, i was using iphone 5, and it worked as perfect as advertisement. However, it was the old time, because after a long time using samsung phone, i changed to use iphone which is iphone 6 plus again. And it doesnt work any more! It works only when i open the app, but it doesnt when i let the app run on under (even the screen is on or off). As a result, I think it doesnt automatic connect the iphone and macbook anymore, and if so, i dont think this is a creative app because its not convenient as what we wanted when we purchased. I hope the developers of this app could fix those errors in the next version. Otherwise, no one would purchase this app anymore in the future.

I love the concept and it’s relatively nonintrusive to have running for now, but it’s basically useless. It works twenty minutes after I need it or never. I’ll keep it running for a bit, but after a few months of this, it needs an update or I’m just going to give up.

This could be one of the most useful apps I have on my phone. Almost magic.

Too slow to be useful
