B-Donor is different .. Blood donation app that considers user's privacy as first priority. Donor's data will not be available to anyone as donors who will receive notification on their mobiles for requests of compatible blood group near to their saved location. Requester will not know contacted donors. Donor also may go to hospital and donate blood without even a phone call. The app uses your location only once during sign up then send notifications based on location you selected on the map not current location. This means that user can revoke Location Services access after sign-up. Save Lives ... Donate Blood
