Lumm

Lumm is a zero-text check-in for couples.

No chat. No messages to write or read. Just one button: tap it, and your partner’s phone glows and buzzes — a quiet “I’m thinking of you” that doesn’t need words.

How it works
Pair with your partner once using a one-time code. After that, tapping Pulse sends a haptic buzz and a soft glow to their phone — instantly if they have the app open, or the moment they next check it if they don’t. A home-screen widget shows the same glow without even opening 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, picking an emoji, or starting a conversation. It’s built for the moments where a text feels like too much, but silence feels like too little.

Built for two
Lumm only works between exactly one pair. There’s no feed, no contacts list, no discovery — just you and the one person you’ve paired with.

Privacy
Lumm doesn’t ask for your name, email, or phone number. Pairing uses an anonymous device ID, and there’s nothing to collect beyond what makes the pulse work. See the full privacy policy at https://lumm-54c3e.web.app.
