This document proposes a Lifesaver E-Blood Donation App Using Cloud that aims to address issues with current blood donation systems. The proposed system would create a centralized blood bank database accessible through a toll-free number. An algorithm would identify the most eligible blood donor based on willingness and location. A user in need of blood could search the database and be connected to an eligible donor. All donor and blood bank information would be stored securely on the cloud. The goals are to motivate blood donation and help patients receive blood quickly during emergencies by connecting donors and those in need.
