Echo is your personal notebook for the people you care about. Life gets busy. You mean to call your uncle, check in on a friend after their surgery, or ask your coworker about their big trip โ€” and then weeks pass. Echo makes sure that never happens. YOUR PEOPLE, ALL IN ONE PLACE Organize everyone in your life โ€” family, friends, colleagues, neighbors โ€” into relationship circles that make sense to you. Each person gets their own profile with the details that actually matter: their favorite coffee, their kids' names, where they grew up, anything worth remembering. NEVER FORGET A CONVERSATION After a lunch, a call, or a catch-up โ€” log a quick note. Next time you talk, you will know exactly where you left off. No more scrolling through months of old messages trying to remember what they told you. ALWAYS KNOW WHEN TO REACH OUT Set follow-up reminders for every person โ€” every 30 days, every 3 months, whenever feels right. Get reminded about birthdays, anniversaries, and special dates before they happen. The Timeline shows you exactly who needs a little attention today. THE LITTLE THINGS MATTER It is the small details that make people feel truly known. Echo helps you be the friend who remembers. The family member who shows up. The person who asks the right question at the right time. BEAUTIFULLY PRIVATE Everything stays on your device. No cloud, no accounts, no tracking. Your relationships are personal โ€” your data stays that way too. Import contacts from your phone in seconds and make the app yours with five beautiful themes: Slate, Sienna, Cove, Mystique, and Petal. Echo is for anyone who wants to be a little more present for the people they love.
