Read full descriptionHide full description
**Slow Letters** is a correspondence app for people who want depth over speed. Every correspondent is built with a full life dossier from birth onward: childhood, habits, relationships, turning points, and emotional rhythm. When you write, your letter enters this living context, and the reply reflects that character's history and current mood. What you can do: - Move between the `Relations`, `Discover`, and `Account` tabs - Browse correspondents with profile archives and timeline context - Write the first letter, save the relationship draft, and wait for the exchange to unfold - Review recovery, language, sign-out, and account deletion controls in `Account` Slow Letters is not chat. It is a slower, intentional form of communication. Terms of Use: https://app.justlove.work/terms?locale=en-US
