The G+ app on the Android Market has been updated to make it compatible with the latest dish from Google, Android Ice Cream Sandwich. The G+ app seems to be one of the first apps to be optimized to run smoothly with ICS. According to Phandroid.com the update:
…features the usual bug fixes as well as the revamped ICS UI. Also added is the ability to actually sign-out of the app (something I’ve been asking for since the app’s inception). You can also look forward to battery life improvements and an easier to navigate UI complete with the ability to now add people to a circle, from a circle profile.
TIt does not seem that many people are aware that G+ has a mobile app. If you use G+, now you can enjoy a more fluid experience on the go.
