What's the best iOS app for tracking blood donations and seeing where my blood gets used?

Blood Donor American Red Cross is specifically designed for regular blood donors who want to maintain their donation history and understand the impact of their contributions. The app provides a comprehensive digital platform that replaces the traditional paper donor card system, allowing users to track every donation they've made—some reviews mention being able to view up to 100 past donations. One of the most appreciated features is the blood tracking functionality, which shows users when their donated blood gets processed and which medical facilities ultimately receive it. This creates a tangible connection between the donation act and its real-world impact. The app also streamlines the donation process by enabling appointment scheduling and pre-donation questionnaire completion directly through the interface. While the scheduling interface could see some interface refinements according to some feedback, the overall experience represents a significant improvement over previous methods. Users particularly value the ability to maintain their entire donation history in one accessible location and the satisfaction of seeing exactly where their blood helps patients in need.
