Description by Luu Thi Tuyet Minh Written by the developer, not by AppBrain. Click to read.
Murmur is a private promise box for the small commitments that shape your relationships.

Capture what you promised, who it was for, when it matters, and the context around it. Instead of treating every promise like another generic task, Murmur keeps commitments connected to the people in your life.

Use Murmur to:

Save promises for family, friends, partners, colleagues, or yourself
Group commitments by person
Add due dates, importance, context, and emotion
Set gentle reminders before something is due
Review overdue, upcoming, and open-ended promises
Mark promises as kept, broken, cancelled, or pending
Reflect on your follow-through over time
Protect your private commitments with Face ID or Touch ID
Keep a calmer record of what you said you would do
Murmur is designed for personal accountability, not pressure. It gives you a quiet space to remember the promises that are easy to lose in everyday noise: a call you said you would make, a plan you wanted to follow through on, a favor you meant to return, or a small act of care that still matters.

Your commitments stay organized in a warm, journal-like space built around people, not projects.
