knock ss

With the iPhone 5s, Apple made security more convenient by allowing users to unlock their devices with a quick tap of its Touch ID Home button. It’s kind of like having a password, without having to type it in every time.

And that’s essentially what Knock, a new iOS app by Knock Software, does for the Mac. It allows you to keep your computer secure, without having to type in a password every time. Simply give your iPhone a knock to unlock…

How does it work? After installing Knock to both your iPhone and Mac, you’ll pair them using a secure, low-power connection. Then, anytime your iPhone’s within Bluetooth range, you can knock twice to unlock your computer.

From the App Store’s description:

“Faster and safer than typing a password, for iOS and Mac.

You keep your iPhone with you all the time. Now you can use it as a password. You never have to open the app— just knock on your phone twice, even when it’s in your pocket, and you’re in.

Using Knock won’t drain your iPhone’s 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.”

And here’s a video of Knock in action:

As always, it’s cool to see developers think outside the box to help make tedious tasks more bearable. I believe we’ve seen a few apps similar to this, but even so, Knock looks polished, convenient, and I can’t wait to try it out.

Keep in mind that because it uses Bluetooth 4.0, your computer and iPhone must support the technology. That means you’ll need an iPhone 4s or newer, and a 2011 MacBook Air/2012 MacBook Pro/2012 iMac/2011 Mac mini or newer.

If you meet those requirements, and want to check it out, you can find the Knock iOS app in the App Store for $3.99, and the accompanying Mac app on the Knock website, for free.

So, what are your thoughts on Knock?

    Sucks this isn’t compatible with my mac… I paid $4 for it too :/ Claimed for a refund though 🙂

    • Guest

      I have the 2011 model too, sucks 🙁

  • arrontaylor

    wtf $4

  • appleyay

    no thanks

  • Jeff Ramirez

    The price will eventually go down. I’ll wait…
    I’ve gone years “manually” inputting my password, I think I’ll wait this one out guys.

  • Jacob S

    It is actually good, really worth for $4? Not sure yet. Working fine with my Mac Mini 2012. You have to have the app running on your phone (in the background) all the time to get it pair with the mac. So far I like it 🙂

  • Tony Trenkle Jr.

    Someones gonna crack their screen by doing this. lol I like the concept though.

    • iBanks

      Knock… Not punch. 😉

      • Tony Trenkle Jr.

        If they knock on their screen hard enough. And what if it doesnt work at first you know people are going to “knock” harder. Humanity is not smart enough to NOT break a couple screens doing this. lol

      • iBanks

        I see your point but don’t see it at all possible to crack these displays by a knock or punch while in pocket.

      • Tony Trenkle Jr.

        Maybe it wont be in their pocket though.

      • Loke1988

        You can knock on the back of the phone in ur pocket.

    • Alexander Tranceswift Sundiev

      Try tapping it with several fingers. It works perfectly for me.

  • josteinliverod

    Love it! Not sure if it’s worth the price, but it’s pretty cool.

  • iBanks

    I love how people try to justify what a developer should price their app’s worth.

    • KraKsX

      Customers always define an app is worth. When developers price to high, the sales suffer, and this is due to consumers beliefs of ‘right price’.
      Apps given away free are a hit and miss
      Apps given away to cheap tend not to last long
      Apps priced perfectly are the best for all
      Apps priced to high fail to reach as many customers as it should

      • iBanks

        I wish I knew the science to the “perfect price” I agree with some of your points, but because another app is priced better than another doesn’t make it the “wrong price”… It’s what the dev feels based on the work put in I believe.

      • KraKsX

        It is a science determining the correct price, and some of that has to go on before the work is done, to see if it will be a worthy investment in time. Take this app, just as an example; Is it worth $1 (of course it is), and keep going up, dollar by dollar. Im sure at one point you will even say that its not worth X amount.
        Use Adobe – PhotoShop as another example, at one point priced WAY to high! And it became the most pirated, cracked, hacked software out. Instead of lowering prices Adobe kept trying to stop it, and it never worked. This is customers DEFINING the correct price. regardless of what the developers believe the worth is.
        Now back to this app, we go back to the number you chose as X, if this became the sale price, maybe one or two people would try it (maybe no one), and thats because the lower the price the more opportunities for sales. Would this sell 5 times as much at the price of $1, making the Developer MORE money, maybe…. And there in comes the science of it…

      • Alexander Tranceswift Sundiev

        Customers will pay even if the price is high given the idea is great.

  • KraKsX

    If it was $1 id give it ago… but $4 is not worth it, I’m already used to typing in passwords anyway.

    • iBanks

      Why even give $1 rather than $4 if you’re used to typing in passwords? Just curious.

      • KraKsX

        because its more of a gimmick, a cool trick, something to play with. So I feel its worth something, but not worth enough for me to pay $4

      • iBanks

        I can respect that. To some, it brings a convenience factor so worth the amount.

      • KraKsX

        For some Im sure its worth more, for many its to much. Thats just the way it is. I think its a good idea. And like I said, if priced for me, I would have already purchased it.

  • Blake Anderson

    I decided to splurge and buy it. Really cool app and it works very well. Very convenient because typing in a long password has always been tedious. And 3.99$ is not that much.

  • Just a novelty, funny though. Besides IMO password locking your Macbook is not a great idea. Thief steals it, notices it’s locked, wipes your Mac/drive.. if you let him login and do something there’s a bigger chance you can trace it’s location or some other kind of activity (even more so if you have something like Prey installed)

  • chumawumba

    What about keycard? Just like this but a bigger rip off

    • iBanks

      What makes this an rip off?

      • chumawumba

        The reviews speak for themselves

      • iBanks

        Lol! The reviews huh? The app performs as advertised, not sure how that would consider an app an rip off.

      • Andreas

        I bought it thinking it would probably run worse than in the commercial, but it really doesn’t. It responds perfectly (I tend to be sceptical with stuff like this), so I don’t know which “reviews” you speak of.

      • Loke1988

        Last time I checked there were no reviews. I did post one 5 stars.

    • Luke Mulholland

      Keycard worked fine on my mac. It used to be glitchy where it would lock my laptop despite the fact my phone was sitting right next to it, but they updated and all is good.

  • Mark

    Yes it makes unlocking easier, but I don’t see it as secure.

    • Alexander Tranceswift Sundiev

      As long as you have your phone on you, it is secure.

  • Mounir Toumi

    it’s really stupid, now everyone can unlock your mac if your phone is in the area… not cool, not gonna buy it…

    • Andreas

      Hopefully you wouldn’t leave your phone in an area where “everyone” is. It’s mobile, hence MOBILE phone xD

      • Mounir Toumi

        trust me, your family member will find it charging on the dock and you’re taking a dump and he’s gonna knock …

      • Loke1988

        Why would u tell anyone you have it?

      • Andreas

        Not only that, but does he not trust his family members? I gladly borrow my computer to my family, but they would never touch it without my permission (even with no password). Therefore I can easily trust them with something this small. (And what is so secret on your computer that you can’t put in a hidden folder)?

      • Andrew Householder

        why wouldnt you have your phone while you’re taking a dump? are you some sort of savage?

      • Mounir Toumi

        yea that’s right, hiding behind your f*king monitor and calling people savage, sick f**k

      • Andrew Householder

        i cant tell if you’re trolling me or not here. if so, bravo. if not.. you just made my post literal instead of a light-hearted joke.

      • Alexander Tranceswift Sundiev

        quit the app when you don’t use it 😉

  • Prasoon Singh

    Sucks that it doesn’t work with the 2011 MacBook Pro. I requested a refund though.

  • Loke1988

    Knock knock? Who’s there?

    This guy who just knock knocked to log in and post this!

  • Lol, nice gimmick. Can already do that with picture passwords withouth living Bluetooth enabled…

    • Loke1988

      Yeah but your stuck with Windows?

      • I’d much rather be stuck with “freedom to make your device look and work the way you want it to” (i.e. Windows) than move to highly restrictive and non-flexible, but more noob-friendly “we know you more than you know yourself, thus we know what you want” (i.e. Mac OS X).

      • Alexander Tranceswift Sundiev

        What’s wrong with having both? 😉

      • Running in a virtual machine just bugs down the performance. If you use Windows once in a blue moon, that’s no problem for you. I on the other hand, use Mac OS X once in a blue moon, so, have it set up (on my Surface Pro) similar to what this guy demoed (http://bit ly/HKb5Af).

        Back to the topic, I still wouldn’t consider paying that hefty price tag for a 1-function application. That’s a total rip-off IMO, but Mac users probably wouldn’t care to think twice.

      • Alexander Tranceswift Sundiev

        I agree, however I meant having 2 computers, PC and MAC. This way you can have the best of both worlds. VM’s are good for debugging and testing though.

      • I have the cash to get one (hence why I could afford a Surface Pro), but honestly, I wouldn’t consider getting a Mac even if I were a millionaire. I personally find them a rip-off as I value functionality and flexibility a lot more than just beauty.

      • Alexander Tranceswift Sundiev

        There’s more to it. Read up 😉 have a nice day!

  • Jay Kay

    very limited functionality, why bluetooth why not on same Wifi, Sorry its not for me.

    • Andreas

      Wifi has a span to big for this stuff. If it were on wifi I couldn’t use it since my school has wifi throughout the school. I could easily be about 100m away and be connected. Bit stupid situation for me :/
