Marco – Friend Check-In

A quiet line to the three people who matter most. Send a Marco to say "thinking of you," get a Polo back, or ask for help with one tap. Now on Apple Watch.

Marco Polo is a quiet, private way to stay close to the three people who matter most.

No feeds. No likes. No ads. Just a simple, reliable line to your inner circle.

HOW IT WORKS • Send a "Marco?" — a wordless "thinking of you / are you okay?" — by holding a friend's card. • Get a "Polo!" back — an easy, one-tap "I'm okay." • Need Help — when something's wrong, one button alerts everyone in your circle right away.

BUILT FOR YOUR CLOSEST PEOPLE Your circle is capped at three on purpose. Marco Polo isn't a social network — it's for the handful of people you'd actually call in the middle of the night. Parents and kids. Partners. Best friends. The people you want to keep a thread to without the noise of group chats.

MAKE IT YOURS • Rename your "Marco" and "Polo" to anything you like. • Signals you can feel — gentle haptics, sound, and motion, not just another badge. • Beautiful, calm, dark interface that gets out of the way.

ON YOUR WRIST The Apple Watch app lets you check in and respond in a single tap — perfect for a quick "I'm okay" without reaching for your phone.

PRIVACY FIRST • Your phone number is stored hashed (SHA-256) and is never shared with other users. • Your custom messages are encrypted (AES-256-GCM) — only you can read them. • We never sell your data, share it with third parties, show ads, or track you. • Export your data or delete your account anytime from Settings.

Marco Polo is free. Download it, add the people who matter, and keep a quiet thread to the ones you love.
