The occasional unregistered gesture
These days it’s so rare to come across a new app that adds personalization and wonder: “how is this not a standard feature”. Knokr is an app that allows you to quickly access apps by performing gestures while your screen is turned off. First it is worth noting that, as stated in its Google Play description, the gestures only work on devices with OLED screens.
Now let’s start from the top: once installed you can open up the application and set what action each gesture will perform. You can set an up-down swipe to unlock your phone, a down-up swipe to open your contacts app double tap or long tap to quickly open YouTube etc. Once you’ve set the basic gestures you can switch to more advanced ones such as drawing arrows, double arrows and circles. Furthermore, while the app is running you can quickly launch your camera while the screen is turned off by holding the device in landscape mode and pressing the volume up key.
The gestures were easily recognized by my screen when performed. There was one or two that i had to repeat in order to register but it was hardly noticeable. It would be nice to have the option of adding your own custom gestures and set them to launch what you want but the app is still in beta so there is yet a chance this feature may make it in someday. In the meantime there are plenty of standard gestures to use.
It adds a way to quickly access exactly what you need, when you need it. The only drawback i could find was that my power button no longer turned on my screen, but you can just set a gesture to unlock so the need for turning on the screen via power button is eliminated anyway.
