A free app for Android, by Lalsangpuia Ralte.

The Mizo Keyboard LITE is a handy mobile application that allows you to type the Mizo alphabet without switching to the English QWERTY keyboard. This app also has the new ( ₹ ) and old ( ₨ ) Indian Rupee Signs, making it easier to type them out while texting or chatting someone.

It’s a lightweight that will not take too much space in your phone. Unlike other keyboard apps, though, this one does not have auto-suggestion/prediction, voice input, or user dictionary.

However, it does have other key display options when you hold a key. For instance, holding the Enter key will display a smiley.
