Calcalling Apps TV is a unique Android application which contains different types of video from the city on varied subjects.
"The app will work as a video magazine telling stories about Kolkata's rich and bold culture, heritage, art, literature, lifestyle, food, festivals, etc," the app's co-founder Koushik Mullick said.
The app, launched by Brand Next and Deadline Media, would be free to download and would be updated everyday.
"We have a dedicated team of people who will go to the field and shoot the videos and then upload it," he said.
The number of global TV app users on smartphones is expected to reach nearly 1.29 billion by 2018.
