BLOOD4Pune is a social project .The purpose of this project is to develop a solution using the social media platform to overcome these unsolved problems. In this we propose a Bot for the blood request system. The bot makes possible interaction between patients or anyone in urgent need of blood and the blood donors across the Pune city. Anyone who is in need of blood can tweet by tagging our account Blood4Pune in their tweet and within 30 seconds the bot will like and retweet the tweet automatically. Using this service we have made an attempt to make use of the capabilities of social media platform and mobile phones and turn them into lifesaver online health care service which is convenient to users and can help in reaching out to donors across the city.
