Let's Metta is an anonymous "I thought of you today" button. You think of people more often than you ever say — a song, a memory, a passing thought. Most apps turn that into an obligation: a message to write, a reply to wait for. Let's Metta removes all of it. One tap. The recipient sees a number — never who, never how. Built on the Pali idea of metta: wishing someone well without expecting anything back. No feed, no replies, no ads, no tracking. Just a silent hug.
