Next Eligible Donation Date – Blood Donor American Red Cross Review

It would be really great if the app could calculate the next date when I would be eligible to give blood. I would rather give every 56 days (+,-) than donate a power red. Therefore I need to calculate when I’m eligible and how long I have to give if I want to make my locals parish donation blood drive.
