Meine Spendeorte
Verwalten Sie Ihre bevorzugten Spendeorte und lassen Sie sich per E-Mail erinnern, wenn an diesen Orten ein Spendetermin stattfindet.

Forum
Tauschen Sie sich mit anderen Blutspendern aus ganz Deutschland aus.

🌍Geographic ReachNot ranked
This app is currently outside the top 100 grossing in all 9 countries we monitor (US, UK, DE, FR, JP, CA, AU, BR, IN). Niche or new apps often launch this way — popularity rankings appear once daily revenue clears the regional threshold.
Profile is built from iTunes Lookup + developer site scrape + ML revenue model. Empty fields show "Not found" — additional sources (Crunchbase, X, IndieHackers, Acquire.com) coming.
