The Android app ecosystem may not be lacking compared to iOS, as it was before. The Play Store is now filled with some quality apps from top developers that mostly follow the design guidelines laid down by Google.
However, accept it or not, there is still a lack of a decent Twitter client for Android. The official Twitter app for Android is absolutely horrible and slow, while Plume, Tweetcaster and others seem to be designed by a high-school going kid.
Thankfully, the developer of Falcon for Twitter – a full featured Twitter widget – has released a new Twitter client for Android, based on his Twitter widget, Falcon Pro.
The app is still in beta, and does lack certain features that Plume or Tweetcaster have, but it looks much better and polished. The developer has also taken effort to optimize the app for tablets. The app will work on any Android 2.2+ devices.
Falcon Pro for Twitter is still in beta and the APK of the app can be downloaded from this thread on XDA forums. The developer plans release the app on the Play Store after beta testing it for sometime at a nominal price.
