This app is for those who play the game Ingress. We all have many portals under our name, but we are not able to
calculate or keep track of the number of portal held days. This app will help you in counting the portal held days.
After you capture a portal just open this app and select the date and write the portal name. And the rest will be taken care by the app. In this way you can track of your Next Guardian Portal easily.
