A note about warnings
Your phone may warn you that the downloaded APK could be dangerous and is from an unknown source. This is because the app is not hosted on Google's Play Store. If you have a newer Android phone, it may also tell you that app is blocked by "Play Protect". This is Google's latest security measure to warn you about apps developed for a lower Android OS than Oreo 8.0. You will also have to ignore this warning and choose to install the app regardless. Notices about the app having being developed for older Android version can also be ignored. The app has been tested with Android 10 and found to be working just fine. We will, however, soon bring out an update, which will remove some of these warnings.
An APK (Android package file) is an installation file for an Android application. ↩
