Private beta for iPhone

Private notes for the few who matter most.

Klosr is a quieter iPhone app for saying something real to one person at a time. Write by hand. Send your voice. Keep what matters. Nothing generated. Nothing performative.

No AI No feed One thread per person
What it is

A smaller kind of communication app.

Klosr is for the people you would actually write to. It stays one-to-one, private by default, and focused on real expression instead of content, feeds, or social performance.

01
One private thread per person.

Every important person gets their own place. No group chaos, no shared room full of everyone, no feed to manage.

02
Handwriting and voice come first.

Write by hand, send a voice note, or capture a moment. The product is built around something that feels authored, not optimized.

03
Private by default on iPhone.

Sign in with Apple, add someone from Contacts, and keep the experience close to the device instead of building around a custom backend.

What Klosr is not

This is not a feed, a relationship dashboard, or an AI writing layer.

The product should never tell you what to feel or what to say. It should only make it easier to send something real.

No generated intimacy.

No AI writing help, no canned emotional prompts, and no prewritten note library pretending to be closeness.

No emotional scoring.

No moods, no relationship taxonomy, no product layer trying to interpret the connection for you.

No social performance.

No public profile, no audience, no growth loop. Just one person, one thread, one real note at a time.

How it works

The first successful loop should feel obvious.

Sign in. Add one person. Send one real note. Get something real back. Everything else is secondary.

Step 01 Sign in with Apple.

Use your Apple account first, then finish your profile with the details you actually want your people to see.

Step 02 Add one person who matters.

Bring them in from Contacts and keep the circle small. The app only gets better when the list stays honest.

Step 03 Send a handwritten or voice note.

Write something in your own words, in your own handwriting, or in your own voice. Nothing prewritten.

Step 04 Save what matters.

Keep the notes you know you will return to. Journal keeps quieter pages. Saved holds onto the personal ones.

Built for now

An iPhone app for people who still want to say something like a person.
