Write Tamil Letters is a free Android application developed by Sathish Shanmugam that helps users learn the Tamil alphabet. The application offers a variety of features to make the learning experience interactive and engaging.

The app has seven categories, including Uyir Ezhuthu (Tamil vowels), Mei Ezhuthu (Tamil consonants), Ayutha Ezhuthu, and more. Users can practice writing Tamil letters and hear their pronunciation through the app's voice feature. The app also allows users to choose their favorite color and pencil size for writing and has an erase option for mistakes. The Next and Previous buttons help users navigate through letters, and the Play button allows them to hear the letter's voice. The table view option is handy for learning Tamil alphabets.

Overall, Write Tamil Letters is an excellent app for anyone who wants to learn the Tamil alphabet. It is easy to use, engaging, and provides users with all the necessary tools to learn Tamil letters effectively. I highly recommend it to anyone who wants to learn Tamil.
