There's a pause between typing and sending. That's where most damage happens, and where most people have no help at all. CalmMessage sits in that pause. It reads what you wrote, spots where tension is hiding, and gives you a steadier version. One tap. Around three seconds. Terms of Service: https://www.apple.com/legal/itunes/appstore/dev/stdeula You stay in control. The rewrite is advisory, not authoritative. Edit it, ignore it, or toggle back to your original. Nothing gets sent without your say. One week free. Then decide. CalmMessage turns the message you'd regret into the one you meant: de-escalate, set a boundary, or just make it shorter. Every rewrite is checked against your original intent, tone, and strength before you see it, and flagged phrases show you exactly what changed. And unlike other AI tools, the message you send is still unmistakably you.
