Dale Kelly of evfirst.com has created the evFirst Android app. It is a beta version up on Google Play. At the moment you can use the app to find your nearest charger, view its reliability, check-in (if you are close enough to it), change its status, add/vew comments, view check-ins and view the charger in Google Maps navigation.
Other features include: View Nearby Chargers, which shows a list of chargers near your location, view inbox (to see your evFirst messages), send messages, view announcements and view events. The app requires Android 4.0+, GPS and an internet connection.
