OnyxGTracker

Tired of losing track of when your Ingress guardians will get the Oynx badge? This app will be a helpful tool for you to make sure that doesn't happen anymore. Just enter in the name of your portal and the date it was captured. The app will keep a list of all your guardian portals and their Onyx due date. Want to help other members in your faction? You can keep track of their portals! Or, if you're nefarious, you can keep track of the opposing factions portals too!
