Knock – unlock your Mac without typing a thing. Your iPhone is the password.

Tried reconnecting the Bluetooth on my Mac multiple times and it constantly disconnects        Disconnects frequently

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           Works intermittently

I have a password that is long enough to be useful and find Knock a great time saver Recently Ive 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                 Excellent Tech Support

Works one day very well and have to reinstall it to get it to work     One day app

It hardly ever works Im having connectivity issues with my Apple Watch There are several troubleshooting tips for the problem Im having that even includes terminal commands I dont have time to jump through a bunch of hoops just to get an app to work Its much easier for me to type in my password Not worth 5 IMO     I do not recommend this app

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                 Awesome

Wont pair with my phone Totally useless     20 does not work at all

After a few weeks of fantastic use the app stopped working and nothing I do seems to fix it Ive reset the Bluetooth connection Reinstalled Relaunched after boot ups It simply never works anymore After reading through the comments it seems this is a very common problem        Stops working after a few weeks

I really wanted to like this product as it seemed like a great idea The problem is if your Mac has been asleep for a while you can knock on the app until your hand fell off and it wont do anything Also I found them to be VERY misleading in how they showed how this worked They showed a guy on their website just knocking on his phone WHILE IT WAS IN HIS POCKET mind you and the computer magically turns on What they DONT tell you is that while that sure looked great you would have to take your phone out open it get the app open then put it back in your pocket with the screen still on THEN you can do that trick Not quite as simple as just walk up to your computer tap your phone and your computer unlocks They SURE presented it that way Pretty blatantly misleading if you ask me     Such a Shame

Works great                 Works for me

Probably the worst purchase Ive ever made on the App Store Seems like a great idea but in practice it takes so long for the app to be ready to unlock my MacBook that I can manually type my password 5 times maybe even 10 Just for fun Ive clocked how long its taken and its been averaging almost a minute Really thought this would be a great Apple Watch app but the sluggishness just makes it useless     Just Doesnt Work

This worked great I could knock my phone while in my pocket screen off no app open boom just worked But now No connection is happening Something is broke guys           Something is broken

Worked at first when it synced computer and phone together Hasnt worked since Was hoping this recent update would fix it but at this time I wish I wouldnt have wasted the money in this app     Doesnt work

Very inconsistent and unreliable Maybe 5 of the time t connects and works as it should The other 95 I waste my time futzing with it and then end up logging in anyway with my password and loathing myself for being gullible enough to buy it Dont repeat my mistake     Horrible waste of 5 Should have trusted the reviews

I love this app it works perfectly on my phone and apple watch                 Not sure why there are negative reviews

I was super excited for this app after I had heard such good things on other websites but it seriously only works like 1 out of 100 times If you want a good app for a quick unlock get MacID     DO NOT BUY THIS APP The only thing this helps unlock is your frustration

So I was a bit uneasy when buying this app because of the misguiding comments but after much research YouTubeGoogleetc I finally had the nerve to buy the app And I am not disappointed This app really works as advertised and it works while I use other apps on my phone which I thought it was pretty neat The setup with almost instant and works when my iPhone is locked Yes it really does however you have to Wake up the computer first WAIT for the circle to fill up THEN knock Trust me there really isnt any lag or wait time Maybe just a second or two But very useful app I recommend it to those who have very long passwords                 Works Perfectly

I purchased and installed Knock as soon as it became available Its really cool to see it work Its installed on my MacBook Air and my iPhone 5s On the MBA when I wake it from sleep or when I open it when its closed I have to enter my password For me the security of the required password is not an option but frequently entering a long password is a real pain Knock is what makes it work I knock on my iPhone twice when I want to wake the MBA and its open for business It looks amazing and it is The app uses lowenergy Bluetooth to communicate between the MBA and the iPhone Apple has made frequent changes to networking on both devices and Knock Software has had to stay on their toes There are frequent automatic updates but Knock has broken several times mostly I think by changes by Apple but also a few friendly fire episodes Ive come to rely on Knock so Im frustrated and annoyed when it fails Fortunately support is top notch Knock responds to my emails within a day and theyve always come through with solutions I strongly recommend Knock FYI Im running Knock with the MacOS 10104 and the iOS 84 public betas PS My Apple watch is on order and Knock will work with it                 Almost magical

This app works well a very small percentage of the time Most of the time its slow Sometimes it doesnt work at all Occasionally it works as expected Im currently exploring how to get my money back I definitely wouldnt recommend it     Works Occasionally

A great concept but the app works about 10 of the time When it does work it takes me longer to wait for the app than entering my password anyways     Rarely works

Please add open mac function when mac playing screensaver Also please add more function when knock              Amazing but

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        Doesnt work with my iPhone 6 Plus

It worked once on my Apple Watch and about five times on my iPhone 6 Plus and never again no matter what I tried from restarting everything to reloading everything Now Im trying to get my money back     The Knock app

App worked great fun engaging useful unique after a bit you wonder how you got along without it but then a technical problem connecting Their customer service support was absolutely great they were not going to give up on this until it was fixed and fix my problem they did We learned something and I believe they are going to add this info to their help section in case someone else experiences the same issue 5 stars for the product and 6 stars for service                 Great App and Phenomenal Service

Doesnt work consistently MacID works better and costs less     Not worth 5

I would like to use this but the app still has the problem where the setup gets stuck when saving the password This problem seems to be persistent across versions Additionally when the app is running on my Mac the Mac repeatedly connects to every BLE device in the room including other peoples iPhones     Gets stuck at saving password

It worked once then never again Tech support was not able to help     Worked once

The connection is not stable at all        Unfortunately the app isnt working well at all

I love the concept and its relatively nonintrusive to have running for now but its basically useless It works twenty minutes after I need it or never Ill keep it running for a bit but after a few months of this it needs an update or Im just going to give up        Needs An Update Badly

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     Poor quality app

I am extremely disappointed in this app it is certainly not worth the 499 I paid I followed the instructions and set up went okay but the percentage of times it actually works is around 10 I spent way more time trying to get my iPhone or watch to app my mac than it would take to just type in the password Very disappointing Great concept poorly executed I will be asking for a refund     Hit or miss if it works

I was also skeptical after some of the negative reviews but it works great                 Awesome

The developer had been very responsive but after several weeks of fiddling with various settings unlinking 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     I wanted this to work but it doesnt

MacBook Pro is from late 2014 iPhone 6 and Apple Watch It worked for a few days and then started disconnecting whenever the MBP was locked Sort of defeats the purpose doesnt it I reset all devices then uninstalled and reinstalled and then went thru repairing and using iCloud and Keychain settings which had been altered It tested fine Then I locked it and went to the watch and iPhone disconnected Not ready for prime time     Bummer for now

Bluetooth connection is terrible breaks every time     awful app

I would not recommend this app to anyone it only works whe set up first time After that it seems that never works     Grat idea

This is a great app for people who only ever use a single computer However if you have or use more than one this app will leave you wanting        Great for one computer

Works great with my apple watch and iPhone 5s                 Knock

The concept of Knock is great When I first got it it worked maybe 60 of the time but its been on downward slope ever since Now it doesnt work it all It has never ever worked from my Apple Watch I dont 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 Im still entering my password manually and have basically given up on Knock        Used to work but now never

499 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     Are you kidding me

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     Not worth it anymore

Too slow to be useful        Really slow detection of iPhone app

Does not work if screen sleepstakes a moment to connect once screen is out of sleepvery often it is quicker to type password        Great ideapoor execution

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     Worked once

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                 Really Works Well

This could be one of the most useful apps I have on my phone Almost magic                 Holy Amazing App Batman

OS X 10104 running on MPB retina mid 2012 and connectivity has been great I find the watch glance extremely useful and often unlock my Mac as I walk towards it Connects faster and more often than others in my experience                 20 is great

Overall this app takes more time with fruitless efforts to get it to work than it saves when it is functioning as expected Opening the app does nothing no help menu no anything        Great when it works About 30 of the time

but cool when it does Usually on the macs unlock screen the green thing goes around and around as it tries to connect when my phone is right there iPhone 6 brand new MBP        Doesnt work most of the time

But stopped working Then worked after an update and shortly stopped after that Really disappointed     Was great
