Disclaimer: This app is intended for entertainment purposes only and does not provide true motion tracking functionality. Track and detect aliens all around you! just start the application and place your aliens on the screen by tapping or drawing them to see and hear them. The aliens will automatically start to swarm onto your location. The latest update now comes with extra configurations to change how you want the aliens on the screen to behave including how many, speed and lifetime. Alien Motion Detector is fully controlled by the gyroscopes and requires that you have this present in the device you are using. Follow our Twitter @kmonkeyblog

Pip-Toy [Peripherals In Phone - Toy] will help you traverse the wastelands using the built in compass and maps. But wait, there's more! If you act now, you'll also get an angle finder, stat view, and flashlight to boot! STATS shows the current day's (steps, calories burned, minutes of exercise, etc.). Please note, HealthKit data is only available on supported devices, such as iPhones. If installed on tablets, the classic flashlight screen is presented in glorious monochrome in place of the STATS view. Now you can install your phone (assuming it fits) into a PIP-Boy device that came with SPECIAL editions of Fallout 4 and launch the app in Landscape-Cosplay mode (screen resize/reposition)! Just in time for Halloween! Please note: When changing the orientation (portrait/landscape), the app must be closed and reopen for the change to take effect. So with this app on your device, grab your favorite radiated cola and head for the high ground to avoid the fallout! This is an unofficial, fan made, app inspired by Bethesda's Fallout series of games.
