This is the Android client app for Ingress Excubitor. Not much more to say, at the moment.
Excubitor is a helper application for Ingress, to manage your "entities destroyed" emails.
Step 1: Register your Google account on the site, so it can associate the incoming emails with you.
Step 2: Download and install the Android client, and set up your account.
Step 3: Set up your GMail (or other email) account to automatically forward all "entities destroyed" emails to the service.
Step 4: Wait for someone to destroy one or more of your resonators/links/fields.
Excubitor is Latin for "sentinel" or "watchman". It's pronounced ex-OOH-bit-or.
