Territory allows you to switch the App Store storefront of your device.
Developed as a tool specifically for iOS developers, you can use Territory to see if your app has been featured in another country and where it ranks for certain keywords there.
Please note, the language of the App Store will remain your system language but you’ll be able to view the App Store storefront for the selected country. You won't be able to download apps from another storefront without using an Apple ID registered in that country.
Please also note, this app is also likely to never make it to the App Store.
