An offline Malayalam Transliteration App using Mozhi scheme. You can also copy/paste Malayalam unicode text to the input control to convert square characters to Malayalam if your device doesn't have Malayalam font.

You can now use this app as a direct input method (keyboard)
Step 1. Enable keyboard from Home -> Settings -> Language & keyboard -> Varamozhi Transliteration
Step 2. Long press on any input box, touch Input method and select Varamozhi Transliteration
Step 3. As you type, you can see transliterated Malayalam text on top of the keyboard.
Step 4. Touch Malayalam text to replace Manglish text in the input box (You might see only squares if you don't have Malayalam font or text without complex layout, but target device will show text correctly if it supports complex layout and font)

Note: When you copy or share Malayalam text to other apps, it might look as square characters if you don't have unicode font in your device. But it will show correctly if the target device/app has the unicode font. You can test it by sending a sample text from the app to your email and view email on desktop.
