Lumm app icon

A silent way to say
I'm thinking of you

Lumm is a zero-text check-in for couples. No chat, no messages to write — just one button that sends a haptic pulse and a soft glow to your partner's phone.

How it works

1

Pair once

Create a pair, share a one-time code with your partner. That's the only setup — ever.

2

Tap Pulse

One button. No text to write, no emoji to pick. Just tap it when they're on your mind.

3

They feel it

Their phone glows and buzzes instantly — or the moment they next open the app.

Why no chat?

Chat apps are for saying something. Lumm is for saying nothing — just "you're on my mind" without composing a message or starting a conversation. It's built for the moments where a text feels like too much, but silence feels like too little.
