Knockr allows you to launch apps with a gesture from anywhere. With Knockr and an OLED device, like the Samsung Galaxy S5 and Moto X, you can open with a gesture when the screen is off. If you don't have an OLED device you can still use Knockr, just check the 'Lockscreen Only' option in the settings and Knockr will become your lockscreen and you can open any app straight from the lockscreen.
Knockr Everywhere adds a floating button to your screen that when clicked will open the gesture listener so you can launch an app anywhere/anytime.
Tasker Integration gives you even more control of Knockr. Use Tasker to set the parameters you want for Knockr to open/pause. Tasker integration currently is for the "off screen" feature of Knockr. The three options you can choose for Tasker to control are on, off and toggle. On turns launches Knockr. Off closes Knockr completely. Toggle option toggles Knockr sleep (release and reset the screen wake) the same way that the 'Power Management' option does. When using Tasker integration it is recommended to switch Knockr off in the settings and uncheck power management if using the toggle feature.
