WaveUp is an app that wakes up your phone – switches the screen on – when you wave over the proximity sensor.
I have developed this app because I wanted to avoid pressing the power button just to take a look at the watch – which I happen to do a lot on my phone. There are already other apps that do exactly this – and even more. I was inspired by Gravity Screen On/Off, which is a great app. However, I am a huge fan of open source software and try to install free software (free as in freedom, not only free as in free beer) on my phone if possible. I wasn’t able to find an open source app that did this so I just did it myself. If you’re interested, you can take a look at the code.
