Chatropolis for phones
The former of the two advantages is self explanatory.
It connects directly to Facebook's chat and messages feature, allowing you to send messages instantly to all your Facebook contacts.
Tweet Caster packs multiple account support, a well managed splash page and a Zip feature that removes annoying tweets and keywords from your feed, without unfollowing that user.
One of the beautiful things that you'll hear any Android user say about the OS, is the extreme level of customisability that just isn't present on i OS, Windows Phone OS or even BB OS.
Among the many features are a paid version to remove ads, downloadable language packs and themes; think your i Phone is cool, look I can make my Android look the same.
Emoji are available, and custom smileys to use instead of the native offering. Of the more interesting features are the ability to schedule texts so that you don't forget something important, or so that you don't have to wake up at 4am to send THAT text, and the ability to customise notifications.
This means that you can have differing icons, tones and vibrate patterns to help you differentiate between contacts without even looking at your phone.
If, however, this isn't quite the app for you, why not try Chomp SMS or Handcent SMS.
All three apps currently sit at 4.4/5 in Play Store reviews, and cover all your basic SMS needs.
IM is not a dedicated messaging service in the way that Whats App, Skype or Kik are.
This means that there are a variety of custom SMS apps present on the Play Store.
There are so many to choose from, we struggle a little to suggest which one is best, although we're happy enough to say that GO SMS is a decent and comprehensive SMS app.
