Ever tried to run through the rain with your Wear watch? Noticed that the watch is going crazy if rain drops land
on the touchscreen?
There is the theater mode in Android Wear, but this also turns the screen completely off.
This app is the solution! It blocks the touchscreen, but lets you see the watchface and incoming notifications. You can activate the lock from the companion app on your mobile or from the apps list on your wearable. If you activate the "upside down" detection you can turn the lock on by turning your wearable upside down for 2 seconds.
To unlock the screen you also turn the device upside down for 2 seconds or use the companion app.
While the screen is locked, everything is working except for the touchscreen. I.e. the watchface is visible and even the voice commands will work.
