came across this app on google play and i love it: https://play.google.com/store/apps/details?id=com.twoogle

copy & paste parts of the description:

Create custom “Twitter Trends”: Search and view what people are tweeting about everything in real-time. Receive the tweets as they come from the different users from all over the world.

1. Google search: Enter your search into the search panel, and tweets should start appearing about your chosen keyword. The unique experience here is that the tweets will fall endlessly until you stop it or pause it. Note that this does not require user login.
2. Multi-keyword search: Enter more than one keyword and view simultaneous message falls on all keyword searches.
3. Geolocation search: Sometimes you only want to see tweets from a specific area. Using the geolocation you can search based on a location.
4. Tweetings: Twoogle wouldn't be a great Twitter client if it didn't let you tweet. Once you're logged in, you can start writing your tweets straight
away.
5. Retweeting: Retweeting is a way of life on Twitter. Twoogle makes it easy to retweet.
6. Replying: Twoogle's replying lets you stay on topic ensuring that you know exactly what's been said.
7. Twitter timeline: wouldn't be a great Twitter client if you couldn't view what your friends tweet about.
