Hey everyone 👋 I built OneDrop because I’ve seen how stressful it can be to find a blood donor in time. People still rely on calls, group chats, and random posts — it’s chaotic when every second matters. OneDrop connects donors and patients directly — making blood donation coordination faster and easier. The app is fully functional right now, and we’re already working on a new UI to make the experience smoother and more modern. I’ve built this solo using Ktor and FastAPI for the backend — and it’s been a huge learning journey. I’d love your honest feedback on how to improve it, especially around user flow and reliability. If you’ve ever donated blood or wanted to — this project is for you ❤️ Thanks for checking it out!

This is such a meaningful project. ❤️ Finding a donor in time can literally save lives, and it’s inspiring to see a tech solution tackling this real problem. Love that it’s already functional and built solo—amazing work! Excited to see how the new UI evolves.
