A free app for Android, by justoneplanet.
This app allows you to see all the latest and most popular emoticons, in both a standalone and a web browser. The emoticons are super Kawaii (= cute) and are designed with a fun, fresh, and modern look. They are the best way to show your personality and convey your message. You can use them in any chat or text message. They are free! You can categorize them according to your preferred system of classification, and thus set up your personal emoticon gallery!
With this app, you have access to popular picks, recommended ones, and the emoticons in your gallery.
