지정헌혈 is a free iPhone app developed by EVAIN Co. Ltd. that aims to facilitate communication between blood donors and patients in need of transfusions. The app allows users to pre-designate individuals to receive their blood donations, offering an additional method to save lives. With 지정헌혈, blood donations can be conveniently made from the comfort of your own home.

One of the main features of 지정헌혈 is the ability to create blood donation requests. Users can write and publish their requests, which can be seen by all members of the app. Notifications are sent to members who meet the specific requirements of the request, ensuring efficient communication between potential donors and patients.

Another notable feature of 지정헌혈 is the ability to find individuals in need of blood donations. Users can search for requests based on blood type, allowing them to easily locate and help those who require their life-saving contribution.

지정헌혈 also includes a comment section where users can engage in conversations with each other. Notifications are sent to the requestor whenever a comment is posted, ensuring prompt communication and coordination.

With push notifications, users can quickly receive alerts when a blood donation request is directed to them. Similarly, if someone responds to a user's donation request, they will be immediately notified.

지정헌혈 encourages users to support each other, as one day they may also require a life-saving blood donation. Let's come together and make a difference by supporting one another through the power of blood donation.
