Notes

GridHopperTac is a lightweight standalone version of GridHopper.net, but for Wear OS devices. It provides the most essential features of the original GridHopper.net web app in a very lightweight package.

Currently running on a Samsung Galaxy Watch 4 Classic w/display 46mm, 450x450. Other versions will work depending on size. Install by sideloading the APK to a Wear OS watch using Android Studio, ADB, or other compatible APK installation tools.

Quick Start: Click top of screen [GridHopperTac] to enter Options page. Scroll down and click [BACK] to return. Click each option to cycle/increment value. For orbital position, a long press will jump by 10 degrees to save time.
