One letter a day.
For someone who matters.
Just a Letter is a quiet messaging app. You can send exactly one letter per day to each of your connections, so every word counts.



How it works
Connect with someone
Invite a partner, a parent, or a faraway friend with a private invite link. Once they accept, the two of you can send each other personal letters.
Write a real letter
Pick your paper and your handwriting, add a photo, or draw something small in the margin. Then seal it and send it on its way.
One letter a day
You can send each of your connections a single letter per day. The limit is deliberate. It makes you choose your words, and it makes theirs worth waiting for.
