Quick answer
To install a colour trading APK on Android: download the file from the platform’s genuine website, allow “Install unknown apps” for that browser only, open the file and tap Install, then switch the permission off again. If you see “App not installed”, remove any older version, free up storage and download the file again. Never install an APK sent to you in a chat.
What is an APK?
It is the Android installation file. Apps from the Play Store are installed automatically; apps from websites arrive as APK files you install yourself. That gives you more control, and more responsibility for checking the source. See the download checklist.
