GiveHub is a modern, feature-rich Android solution built with Java and Firebase Firestore. It seamlessly connects generous donors with people in need. The app features a complete item-approval workflow, proximity-based location searching, real-time in-app chatting with reactions, FCM push notifications, dynamic Dark Mode, and an intuitive Web Admin Panel.

How It Works (Approval Workflow)

To ensure high quality and prevent spam, every donation item uploaded by a user stays in Pending Status. Once the admin reviews and approves the item from the Web Admin Panel, it immediately goes live for all users, and an automated push notification is dispatched to the user confirming their approval.
