Raktra connects people in need with verified nearby blood donors using live GPS, Google Maps, and Firebase — built for the moments where every minute matters.
Instead of WhatsApp forwards and random lists, Raktra plots blood donors as live map pins, sorted by real GPS distance from you. Donors register once, set their availability, and appear as red pins on an interactive map when someone nearby needs help.
Built with Flutter and Firebase, Raktra is currently in the prototype stage — already wired with live location, Firestore, and a donor-first flow ready to expand into hospitals, colleges, and NGOs across India.
Core features
Everything built for emergencies.

Donor Map Screen
Uses your current GPS position and Google Maps inside Flutter to plot donors as red pins with live distance calculated in real time.

Donor Profiles
Each donor has a Firestore document: name, phone, blood group, availability toggle, and a GeoPoint for accurate distance checks on every session.

Smart Distance Logic
Raktra uses the Haversine formula under the hood to calculate true great-circle distance between the user's live position and each donor's stored GeoPoint.

Blood Requests
Users can create blood requests with blood group and location details so that nearby available donors can respond faster in critical situations.

Availability Toggles
Donors can switch their status between available and busy at any time. Only currently available donors appear as active pins on the live map.

Firebase Backbone
Login, donor data, and requests are handled through Firebase Auth and Firestore — production-ready infrastructure that scales from one city to many.
Firebase Auth + Firestore
How it works
From donor signup to finding a match.
01
Donors register once
Donors sign up inside Raktra, fill in their blood group, and let the app capture a precise GPS coordinate. This is stored as a GeoPoint in a dedicated Firestore collection.
02
User shares live location
When someone opens Raktra to find help, the app requests location permission via Flutter's Geolocator package and captures a fresh coordinate without storing it.
03
Nearby donors are fetched
The app reads active donors from Firestore, calculates Haversine distance for each, and renders only those within the selected radius as red pins on Google Maps.
04
Tap a pin to call
Tapping any donor marker opens a bottom sheet with their blood group, distance, availability, and contact number — ready for the call that matters.

Moksh A. Salecha
BCA Student · Flutter & Firebase Developer · Karnataka, India
I'm Moksh, a Bachelor of Computer Applications student from Karnataka. Raktra is one of my core projects — combining Flutter, Firebase, live maps, and clean UI design to solve a real-world problem: finding blood donors quickly when it actually matters.
Raktra started from a simple question — "What if finding a donor could be as easy as checking a map?" — and it's still evolving with every prototype iteration.
Raktra is a student-led project with a serious goal: use modern app development to make it easier to reach donors when it actually matters — not just during donation drives, but in the real emergency moments that can't wait.
If you're a hospital, college, NGO, or community organizer who wants to experiment with Raktra in your city or campus, reach out. Feedback from doctors, students, and volunteers will shape the next versions of the app.
Right now, Raktra is focused on connecting nearby blood donors using a live map. It already supports donor registration, distance calculation, and map-based discovery — with room to add more emergency features in future versions.
How does Raktra know who is near me?+
The app asks for your location permission, then uses Geolocator in Flutter to get a precise coordinate. Every donor has a saved GeoPoint in Firestore. Raktra runs the Haversine formula and only shows donors within your selected radius.
Where is donor information stored?+
Donor profiles live in Cloud Firestore inside a secure Firebase project. Each document includes name, phone, blood group, availability, and location as a GeoPoint — with security rules to protect direct access from unauthorized clients.
Can we use Raktra in our college or hospital?+
Yes — once Raktra is published, it can be deployed in any city as long as donors register. It's especially useful for colleges, city-level blood donor clubs, and NGOs running donation drives or emergency networks.
When will Raktra launch on the Play Store?+
Raktra is currently in the active prototype stage. The core map and donor flow is working. A public Android release is planned — use the contact form below to get notified or request early access for your organization.
Have an idea?
Help shape the next version of Raktra.
Ideas like blood bank integrations, hospital dashboards, or verified donor programs — practical feedback from doctors, students, and volunteers will guide what gets built next.
Built for the people who care most about community health.
Raktra is especially looking for collaborations with organizations that understand the urgency of blood access.

About Raktra
Blood donor discovery, reimagined for mobile.
Raktra is a blood donor discovery platform built to help people quickly find nearby donors during emergencies. Instead of random lists or WhatsApp forwards, Raktra shows donors that are actually close enough to help — plotted as live map pins, sorted by real GPS distance.
Developed by Moksh A. Salecha, Raktra focuses on simplicity, privacy, and real-world usability for hospitals, colleges, NGOs, and individual donors across India.
