Knocker - Unlock building doors with your voice – no hardware needed

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. My building's buzzer system is like most old buildings in North America: you enter the unit number, it calls the resident's cell, and they can buzz you in. Thanks to Knocker, I've been running key and phone-free for weeks! Knocker transforms traditional cellular-based building buzzers into a voice-activated access system. With our app, you can create voice pins to unlock your building door. It's perfect for so many situations: * Forgot your key and your phone's dead: No worries! * Taking a shower and your partner is at the door: (you haven't given them a key yet 🙄) * Just locked out with no key or phone: Knocker's got your back! * Airbnb hosts: create building pins for guests. * Deliveries: generate one-time use pins for Amazon or Uber Eats. Features: * Create regular and one-time use pins. * Receive notifications for each event. * View a log of all door events. All this for $2.99 per month – super affordable! Curious how it works? Knocker replaces your phone number in the buzzer system with our number. When a visitor enters your unit number, Knocker handles the call. It asks the visitor, "Please say the pin, or wait." If the pin is correct, the door opens. If not, it asks again. No pin? It just calls your cell. Thanks for being patient with the ugly UI – it's an MVP! I can't wait to hear your thoughts and feedback. Let me know how Knocker is changing the way you enter your home! Cheers, Atthar

Wow, Atthar! This is such a clever solution! I can totally relate to the struggle of carrying keys on a run. The voice pin feature is a game changer for sure! I love that you’ve thought of different scenarios where Knocker comes in handy.

Good idea! Congratulations It's so practical and easy to use...

Congratulations on launch of Knocker....

Not sure about North America, but the rest of the world’s Entryphone systems are hardwired to fixed phones, they don’t call cells unless it’s from a gate. I’m pretty sure they aren’t that widespread in North America either. Plus you are reliant on the cell service being up, so could be locked out. I’m sure insurance companies will love this

Also, passers-by will be able to hear what code you use. Is this for apartment blocks or homes. What do you do about your apartment door, leave it unlocked? This is so full of holes. Believe me I work for a long established door entry system manufacturer and we have tried everything, but you cannot compromise security over convenience.
