TingTong Bell

TingTong is a doorbell that rings one person's phone instead of a whole house. You arrive at a friend's door. You tap their name. Their phone rings with a doorbell chime. That is the whole app. No message. No voice note. No content of any kind. A ring carries one piece of information: someone you know is at your door.

Why it exists:

• A doorbell is a broadcast.
• You wanted to reach one person and instead you woke a napping baby, interrupted a work call, or startled a grandparent asleep in the afternoon.
• You had one thing to say, I am here, and the only tool available announced it to everyone.
• TingTong keeps the sound and removes the audience.

How it works:

• Share your six character code with a friend.
• They send a request. You decide whether to accept. Only then can either of you ring the other.
• Tap their bell.
• Their phone chimes. That is it.

Quiet hours:

• Set a window when your bell stays silent.
• Friends see a moon next to your name, so they know before they ring.
• Anyone who came by still shows up in Came by, so you know who was there.

What TingTong does not do:

• No feed. No profiles. No follower counts. No suggestions. No streaks.
• The friend list is a list, not a network to grow.
• The app never notifies you about itself.
• No phone number. No address book. No location.
