The easiest way to activate Siri on your iPhone is to hold down the home button for two seconds. But what if your Home Button doesn’t work properly anymore, or you simply want to activate Siri with a single Tap? Then SiriLaunch is a tweak for you.
SiriLaunch adds a Siri Logo to the bottom of your Notification Center. The position of the logo is adjustable in the settings. So all you need to do to activate Siri is swiping down to get to the Notification Center and tap the Siri icon.
