SmartTap is a brand new jailbreak tweak by well-known developer Elias Limneos. It allows you to use a double-tap gesture on the iPhone’s screen to awaken it, and put it to sleep. You can use other gestures—like a swipe-up or a swipe-down—to unlock the device or launch applications.

The tweak is a homage to the “KnockOn” feature popularized by the LG G2 Android phone, where a double-tap on a dark screen wakes the device. SmartTap is similar, in that you can awaken your device with a “knock” gesture, but SmartTap take it a step further. Check out our video walkthrough inside after the break.

After you install SmartTap, you’ll need to head over to the stock Settings app to find its preferences. Inside of SmartTap’s preferences, you’ll find two different sections for configuring gestures—when the screen is off, and when the screen is on.

When the screen is off, you can use a double-tap gesture, swipe-up gesture, or a swipe-down gesture to perform one of three actions. The actions are as follows: turn on the screen, unlock device, and launch application. To unlock or launch an application, you must use the device without a passcode, otherwise you will be met with an enter passcode screen, interrupting the flow of the tweak.

When you have the screen on, you can use a double tap gesture to lock the device when at the Home screen or when at the Lock screen. When at the Home screen, you can double-tap on any area that doesn’t have any app icons or folders. It’s a bit easier to do on the iPad since the spaces between apps and folders is greater than on the smaller devices.

SmartTap’s “smart touch detection” features is there to ensure that the device does not detect false touches while in your pocket, purse or other places where it could detect a false touch. If you find that you have a hard time getting SmartTap to recognize your input, you may want to consider disabling this feature.

SmartTap Settings

SmartTap works by keeping the device’s digitizer hardware awake even when the rest of the device’s software and components are sleeping. The digitizer is the part of the equation that actually detects the touches on an iPhone or an iPad.

Installing Smart Tap prevents the system from entering idle sleep mode so that the digitizer is available to respond to your touch gestures. The preferences for the tweak contain an option to disable the prevent idle sleep function, but according to the developer, it’s preferred that you just disable the tweak via its kill-switch or Flipswitch toggle.

As you guys know, I’ve never been one to make a huge deal over battery life, but when using a tweak like this, there will obviously be some costs involved when it comes to battery. Limneos states that SmartTap has been tested and optimized so that the battery consumption is minimal, and that most users won’t notice a difference. The verdict is obviously still out on that. I think users who live and die by battery life will definitely notice a difference, but hopefully the difference will be as minimal as the developer states.

The usefulness of a tweak like this is kind of minimized by the fact that there’s still that pesky passcode to deal with. But if you’re someone who uses their device without a passcode, you should definitely check this out. Yes, it’s a bit gimmicky, but it’s still pretty neat to show off to your buddies.

What do you think? Head over to Cydia’s BigBoss repo if you’d like to take it for a spin. It’s available right now for $1.99, and works with the iPod, iPhone, or iPad.

  • iDude

    Awesome Limneos! This is the exact feature i loved with Music Controls Pro by phoenix3200 that was never updated for ios7, i hope you can create a tweak similar to that.

  • Panji

    Will it drain your battery?

    • Captain Canada

      It may not drain your battery but it will definitely affect battery life.

    • Maxim∑

      it changes the hibernation mode of the processor to a lighter sleep. Basically your standby battery life will only drop a little no more than an extra 5%. Your phone only enters deep sleep if its under 20% battery or if its night time/on airplane mode

    htc one copy… lol

    • Sean Cua

    • grumpyfuzz

    • Jeffrey

      you’re all forgetting that this is a 3rd party tweak so it isn’t from apple which means you can’t laugh at apple for copying a feature because they didn’t

        Oh ok then explain why after a year of perfect battery life suddenly my battery lost 50 percent in one night while having installed smarttap. I guess it is magic.

      • PolarHopeless

        It’s not magic. Its an illusion!

  • Sachmach29

    Imagining this probably drains battery similar to Virtual Home’s Quick Unlock.

    • Hash

      The screen stays off the digitzer stays on so it won’t drain much battery. The tweak developer mentions in one of his tweets that you would barely notice the effect on your batter.

      • Damian

        battery drain faster. Looks to me I am loosing about 5 percent per hours when phone is not used. Horrible so far,

  • Razick Rilshad

    Wow cool

  • Iphone5603

    Quick question I have an iPhone 5 iOS 6.0.3 right now and I want to upgrade it to iOS 7.0.6 so I can still jailbreak it. Can i do that? Or there’s no way and only iOS 7.1.1 is my only choice? Pls answer ASAP! Tnx

    • Dao Sasone

      Ur too late. If u update only 7.1.1.

      • Iphone5603

        So I can’t update to iOS 7.0.6 even if I try holding shift and click the custom firmware? Tnx for the answer buddy!

      • Dao Sasone

        Nope. U cant put iph 5/5s in pwnd dfu mode.

      • Andrew


      • Iphone5603

        Ok guys tnx! So I guess I don’t have I choice it’s either I update to iOS 7.1.1 or stay with ios6. What u think guys? Should I update? Or my battery will drain faster on ios7?

      • Varun Soi

        Yu should try something new now its sad that yu won’t be able to get jailbreak in 7.1.1 but ios6 version is too old these day’s so in my opinion if u wnt to stay with jailbreak then wait for ios8 and ios8 jailbreak.!:)

      • XboxOne

        All that time you had…

      • XboxOne

        You’re *

  • Dao Sasone

    Funny how these new jb tweaks that are barely coming has been standard on other devices for awhile already besides ios.

    • XboxOne

      Funny how you care so much.

      • Dao Sasone

        Funny how u assume I do. I just stated a fact. So if u state that gay people are cleaner then straight people, can I assume ur gay? Wait maybe u are. What rk stands for? Real kweer?

  • abdullah575

    what is the wallpaper in the video ??!!

  • Jerwyn Feria

    My problem is that in my pocket, it will butt unlock and mess up applications. Lol

  • Frank Malloy

    Every time I read about an exciting new capability…it’s for jailbroken phones only.
    It’s enough to make you want to go Android.

    • XboxOne

      Then jailbreak!

      • Frank Malloy

        Too much hassle. You can’t upgrade your OS or you lose the jailbreak.

      • Luis Lopez

        Hassle? Hahaha you’re funny, it’s as easy as a simple exe download and no more than 20-25 minutes of your time to successfully jailbreak. And you can only lose your jailbreak if you update it via USB connected to iTunes. And if you never had a Cydia account, if you lose your tweaks you can just look them up again and redownload, plus the settings will be exactly how you had them when you had your jailbreak including paid tweaks. So there’s my two cents on your misled information.

  • Matt

    Ever since the LG phone came out I CRAVED this. So now I’m just like YAAAAAAAAS

  • 0ʇılouɐɯ

    This was invented so long ago and for FREE: it was called “Dim To Black Screen”. So funny Jeff, so funny!!!

  • Saulo Benigno

    No battery info on the post? Really?

    • Damian

      battery drain faster. Looks to me I am loosing about 5 percent per hours when phone is not used. Horrible.

      • XboxOne

        Hate much?

      • 0ʇılouɐɯ

        YES, 5% per hour, and doing NOTHING, I mean with this process only (offline mode and ALL radios OFF!!!). That’s the reason bcoz there is NO battery info in this post!!

      • Damian

        I can confirm now. I left the phone charged up to 77 percent during night when I woke up it was 30. Horrible result. As much as I love the tweak this is a big NO GO for this one

  • Ismail ‘marco’ Azeem

    i bought it as soon as it appeared on cydia and didnt notice any change in battery life yet 😀 will do more tests and get back to ya

  • Batman

    One of my favorite feature on the One M8! It uses the motion sensor to detect whether you are picking up your M8, so it does not drain your batt.

    Apple should implement this on iPhone/iPad

  • Dudayan

    It drained 40% of my iPad’s battery life in 8 hours..

    • Damian

      Exactly, I have similar result. 5 percent per hour.

      I guess developer thinks it is not much

  • Waldemar Sinicki

    It huge drains battery. SHIT fom me

  • VitoM

    Is there a tweak that let’s you answer with on of hard button when someone calling? I work with gloves and for me it’s necessary.

    • Inseltraeumer

      Try activator. I’m not sure what events exactly it can handle, but that’s the tweak I’d try if I were you.

  • Khizar Malik

    Been loving this tweak so far although battery drain is faster !!
    I also have this wallpaper 😀

  • Damian

    Huge battery drain. About 40 percent in 8 hours when the phone is just lying down not being used

  • SkyFall


  • Sunny

    Android had this for years!
    Why did it take this long for this dev to copy!

  • blueleven

    Oh my gosh! Where did you find this? 😮 Thanks!

    • @Orlowskii

      I cut a piece of pictures from the movie and threw it into google graphics.

      “search with pictures”

  • Affected to Hardware Digitizer & LCD short Life Cycle
