Install the Trolling Angles app from the Google Play Store or the Apple App Store like any other smartphone app. It is designed to run on a handheld smartphone device. Although it may execute on an Android or iPad tablet, the user interface may not be ideal.

Upon start of each new version, the app will show a brief update summary and the Terms of Use Agreement, which must be accepted to continue.

At installation, the app is basically Inactive except for providing links to documentation and policy statements. You must activate functionality by purchasing a license or subscription.
