PIP (Peripherals In Phone) is a UWP app to help you traverse the wastelands, using a compass, while you're avoiding the fallout. But wait, There's more! PIP also includes an angle finder / bubble level, flashlight, and now a new themed* map to boot! So with this app on your device, grab your favorite cola and head for high ground!
* Themed maps are only available to devices on Windows 10 Creators Update AND in regions where the map control performs vector rendering, which includes all markets except for China, Japan and South Korea. So your mileage may vary.
