APK stands for Android Package Kit — essentially an installation file for applications built for the Android operating system. It does the same job as installing an app from the Google Play Store, except the file sits directly on your phone. You do not need a separate store account to install apps this way.
The official omgbd Android app is available as an APK file and must be obtained only through official channels. Never use files downloaded from third-party sources or unfamiliar links.
