Hey everyone!
I'm excited to finally launch Knocker! This project is super close to my heart. I created Knocker because I love going for a run every morning, but I hate carrying my keys or phone.

Knocker transforms traditional cellular-based building buzzers into a voice-activated access system. Create voice pins through our smartphone app to unlock your building entrance. No extra hardware is needed, offering a modern, secure solution.
