This is a great little app - if it still worked. Was free, but I’d pay the small app fee if it still worked. ### 1/5 — Don’t Buy *2018-11-08, version 2.0.2* 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. ### 1/5 — App does not work *2018-10-27, version 2.0.2* App does not work. Do not buy this app.... ### 1/5 — Terrible app! *2018-10-22, version 2.0.2* I was charged $6.47 without giving permission. The app doesn’t even open or function. This is a total scam. ### 1/5 — Don’t buy this app *2018-10-17, version 2.0.2* So I bought the app but I can’t use it cause it doesn’t support High Serra yet which it should!!!! What a waste of 5.99 ### 1/5 — Does not work with high sierra *2018-08-02, version 2.0.2* This app does not work with high sierra. ### 1/5 — No updates since 2 years *2018-06-02* Not updated, not working since... ### 1/5 — Video is misleading *2018-05-22, version 2.0.2* What they don’t tell you is that you have to take your phone out of your pocket, unlock it, open the app and then knock to unlock you Mac. It’s a novelty at best and serves no real purpose. Just enter your password and don’t waste your money. ### 1/5 — UPDATE THIS APP PLEASE *2018-05-10, version 2.0.2* 😭😭😭😭😭😭😭😭😭 ### 1/5 — Doesn’t Work *2018-04-30, version 2.0.2* First time I’ve ever taken the time to review an app - just doesn’t work. Tried with iPhone 6, iPhone 8 & Apple Watch - none of them worked. Also don’t give me that “you didn’t install it correctly blah blah” - I was in the 80’s, I know how to basic troubleshoot #KnockOn$#!+ ### 1/5 — No longer works with Mac OS high Sierra *2018-03-29, version 2.0.2* iPhone 7 Plus is linked to Mac and has worked perfectly in the past. However the Mac no longer recognizes knock on the lock screen and shows no ring around my user icon now. Sad as I loved this app and the dev hasn’t updated the app in 2 years ### 1/5 — Very Flaky! *2018-02-22, version 2.0.2* Great when it actually works. But that’s only about 30% of the time. Incredibly difficult to get working at the start. Read the review that says that only older systems have issues. Just bought a brand new iMac, iPhone X and Apple Watch 3. Still having the exact same issues. I’ve uninstalled it. Typing a password is almost as quick and that always works! ### 1/5 — Cool idea but doesn’t consistently work *2018-02-17* Set it up. Worked fine at first. Was excited but didn’t have option to set it up as a glance on iWatch. Wrote developer about that but no response. Therefore, had to go thru a few extra steps to find it on iWatch. In that time could easily type in my password. Then it started only working 1/2 the time. I recommend waiting till it’s more perfected before buying. Great idea just needs to be easier to use and more reliable. To be fair, I have a 2012 computer. Maybe it’s more consistent with newer models. ### 1/5 — not compatible with new devices *2017-12-31, version 2.0.2* does not work with Mac OS High Sierra, which has been out for about 4 months. ### 1/5 — Works sometimes *2017-12-06, version 2.0.2* It works intermittently. I have to wait about 5 minutes before it’ll connect with my MacBook and by that time I could’ve typed in the password 10 times. ### 2/5 — Bummer for now *2017-11-10, version 2.0.2* MacBook Pro is from mid 2014, iPhone 6+ and Apple Watch. It worked for until for a year until I went to High Sierra and iOS 11, and now it just doesn’t. I reset all devices, then uninstalled and reinstalled and now I can pair the phone and MacBook but it doesn’t lock or unlock. I emailed tech support on their site a couple days ago, no reply yet. ### 2/5 — Try Near Lock before this one. *2017-11-09, version 2.0.2* I have had Knock for a while. On the third OS update (High Sierra) things have been better and worse. I won’t go into detail other than the last real app update is 2 years old. High Sierra has been around long enough for some updates. What I will say is that trying Near Lock app it only took me two days and I uninstalled Knock with no regrets. NL is $3.99 for full Version. ### 1/5 — Hasn’t been update in 2 years *2017-11-04* And it shows. It doesn’t run well on newer versions of MacOS or iOS. It takes a long time for the app the recognize that your trying to unlock your computer. I often have enough time to type my password in multiple times before Knock sends me a notification, then it sends two for no reason. Knock was great when it first came out, but the lack of updates have made it pointless to use. ## Most critical reviews (10 lowest-rated) ### 1/5 — Doesn’t work *2021-04-23, version 2.0.2* I’ve installed this twice. It works once. Then never again. ### 1/5 — Could you update please? *2020-07-28, version 2.0.2* I purchased the app and it only worked for a short time until it didn’t, I’m sick of looking at the app on my phone and watch and want to delete it and keep checking to see if it’s updated, and it’s not. ### 1/5 — Doesn’t work for me *2020-04-14, version 2.0.2* Macbook pro mid 2015 Mac os catalina iPhone 11, ios 13.3 Setup finished ok, laptop part of software can see iphone and.. thats it. Can not unlock ### 1/5 — Cash grab app *2020-02-10, version 2.0.2* Developers dropped updates and further development of this app. At this point it needs to be pulled. Don’t waste your money as this won’t work for you. ### 1/5 — Doesn’t work *2020-01-23, version 2.0.2* Used to be a cool app but hasn’t worked for years since they stopped updating it. Super lame. ### 1/5 — Don’t buy ? *2020-01-14* Don’t buy this app if you have newer Apple devices, since it has not been updated since 4 years ### 1/5 — Doesn’t actually work *2019-08-23, version 2.0.2* It’s a simple idea but could install and setup. Getting the phone and mac to connect was hard enough - which is still as they are both Apple’s - and 1 in 10 goes, Knock sees the other end and starts. Look as if it may work then - Blam! Stuck after password entry. Help on their site suggests fixes but nothing worked for me. Waste of money. ### 1/5 — No longer works *2019-06-06, version 2.0.2* No longer works on the updated software ### 1/5 — Lock your iPhone *2019-04-16, version 2.0.2* Ok, how do I lock my iphone? I cant get past this screen to install. Really poor app so far. ### 1/5 — Great concept, bad execution *2019-01-06, version 2.0.2* I love this idea but the app just doesn’t work most of the time.. uninstalling after many attempts to try and make it work. ## Most praised reviews (10 highest-rated) ### 5/5 — Love it *2017-11-25, version 2.0.2* Works great with little to no issues, but it needs an update for the new iPhone X and High Sierra ### 5/5 — Works great! *2017-08-28, version 2.0.2* If you are having trouble with the initial setup, Bluetooth not connecting, you may need to delete the Bluetooth.plist file in the system folder. Instructions on the website!! ### 5/5 — Have been using this since it was released. Great little app. *2017-03-28, version 2.0.2* Really useful. ### 5/5 — Never had a problem *2017-03-08, version 2.0.2* Been using for 14 months now... it's been reliable. Sometimes it does take a few seconds to connect, but I'm never in *that* much of a rush, so I just check for sleepy bugs in my eyes or something in the meantime. You get 3 cool points when you use it in public and someone notices. ### 5/5 — Works Perfectly! *2016-10-15* I saw someone had the same hardware I had, A mac Mini 2012 i7, an iPhone 6s, and an Apple Watch all running the latest software. It works flawlessly! I tried it from 15 feet away and it worked no problem! Both my iPhone and my Apple Watch can unlock it! My only wish is that they offered a Complication for the watch! ### 5/5 — Works Great, Developer Updates *2016-09-24* I've been using this app to avoid typing in my long password and it's been great to me. After sending an email about some macOS Sierra glitches, the developer had an update in a few days fixing all the glitches. It's true that 5% of the time, there will be some sort of disconnectivity between the app and computer, forcing you to type your password. Also if you leave your computer for a few days, it will take the bluetooth maybe 10 seconds to find your mac versus like 2 seconds if you had used your computer recently. These are not really avoidable for the developer so they do not annoy me at all. If you really want some 100% smooth implementation of this feature, buy the $300 Apple Watch. If not, enjoy this highly functional app for $5. ### 5/5 — Works *2016-09-09, version 2.0.2* Does what it says. ### 5/5 — Great App, Great Support from the developer *2016-09-08, version 2.0.2* I LOVE this app. Simple to use, speeds up my day and never fails to impress people when I use it at work. Had an issue connecting after the Sierra GM update - but the developer sent me detailed instructions on how to fix it (under 24 hours from when I sent the distress flare) and it works like a charm again. Well worth the money so buy with confidence. Running on a 2012 MacBook Pro with Retina Display / iPhone 6s+ / Apple Watch Series 1 Aluminium. ### 5/5 — Awesome *2016-08-25, version 2.0.2* Haven't had any problems. Works great. Coworkers are envious. Heads up, this won't wake a sleeping computer. Only fills the password. Still in the long run, saves time & hassle. Highly recommend. ### 5/5 — Great App *2016-07-11, version 2.0.2* Some other reviews don't understand just how the app works, but I've used it with minimal issues for almost two years. I'd recommend it to anyone. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/). User reviews are verbatim App Store reviews.
