Sandhyavandanam is a free Android multimedia app developed by Rajaraman Iyer. It is designed for Tamil Brahmins and provides the Sandhyavandanam sequence for 3 times a day at sunrise, noon, and sunset. The app offers 3 speed variations for beginners, intermediate, and expert users.

Beginner mode has a gap between words that is exactly the length of the mantra, allowing users to recite them slowly. Intermediate mode has a half-gap between words, so users can begin chanting. Expert mode has no gap between words, allowing users to recite along with the app. The app also has a Tamil language option. Users can set the app's language to Tamil and restart the app to see everything in the Tamil language.

Sandhyavandanam is a useful app for Tamil Brahmins who want to practice their daily Sandhyavandanam sequence. With its speed variations, it caters to users of different levels of expertise. The app's multilingual feature also makes it more accessible to users who prefer to use the Tamil language.
