DroppedMyPhone warns you when you —or someone else— drop your phone. It is also a contest of how high (or from how high) you can throw your device.
It relies on a very simple physics model and the fact that most smartphones have an accelerometer, nowadays.
This device shows the forces applied on the phone, which should stay around 1g (if you’re on Earth!), but will get near 0 when in free fall.
This allows us to detect when the smartphone is ‘flying’ and for how long, which determines the distance.
At the end of the day, it was all about creating a visual app that contradicted the typical scope of an app: it’s not really useful and you might end up with a broken phone. :-)
Remember: Never drop your phone in water! ;)
Internet - You need it to send you hiscores to the server, just if you want to.
Write external storage - You need to share the results of your drops and throws as an image. The image will also stay in your SD card, reminding you not to say "I dropped my phone" again ;).
Wake lock - This is effective to detect accidental drops of the phone when the app is not active. From our testing, it does not require much battery. This feature can be turned off easily from the app's menu.
Receive boot completed - If you choose to enable notifications, this will enable them after a reboot.
