This app isn't very nice looking, but functionality-wise it has worked well for me. My only issue is that some event pages with graphics don't scale property, making it hard to read the text. Unfortunately, it looks like this app has been abandoned, as the last update was in 2013.
Good app You'll be getting a few more downloads and deservedly so especially if you see how Meetup completely ruined their own with worst makeover in app history!
Great Works great on MotoX
Useful extra functions not in official app Multiple photo upload facility is very useful, also event descriptions are reproduced fully including photos.
I paid for this bcos not everything works on Meetup using my Android, but all I keep getting is "Expired Time stamp" errors telling me i'm not auth!
Weirdly small (doesn't fill screen on EVO 3D). Free app from Meetup itself is better.
Version 1.1.16 fixes one problem and avoids a few others related to changes in the Meetup.com API. If there are any problems, please send an email to the support email address. A feature and UI update with tablet optimization is in the works.
