Leave Messages in the Real World

Drop a message at a real place for yourself, your friends, or anyone nearby. It appears when the right person arrives.

How It Works

Just three steps.

01

Be There

Kokos are meant to be left where you are, keeping each one tied to a real place.

02

Leave a Koko

Write your koko, then choose how close someone needs to be before it appears.

03

It Appears on Arrival

Kokos appear when you get close enough. If one is left for you, you can get a notification on arrival.

For You. For Friends. For Anyone Nearby.

Create kokos for reminders, surprises, or public messages, anchored to where it matters.

Private

For Yourself

Leave reminders for the next time you come back. A dish you loved, a workout goal, a parking note, or something you don't want to forget.

Save the thought you'll want again, right where you'll want it.

Shared

For Friends

Drop a koko only your friends can see. Perfect for surprises, inside jokes, meet-up notes, and “when you get here...” moments.

A message can stay hidden until the right person reaches the right place.

Public

For Anyone Nearby

Leave a koko for anyone nearby. Share something helpful, surprising, or worth discovering.

Leave something behind for the next person who shows up.

Made for Where You Stand

Koko is built around places. Messages show up when you're actually there.

Where You Are

You create Kokos from wherever you are, and they stay there for others to find.

Place Changes Things

Because kokos are connected to real-world presence, public messages feel more intentional and meaningful.

Your Places, Remembered

Even when you're far away, you can visit your kokos from your profile, each one tied to a real place you were at.

Your Location Your Control

Koko uses your location to drop a koko and show what's nearby. It isn't shared, sold, or used to track you.

Not Shared or Sold

Your location isn't shared or sold to anyone.

No Live Location Sharing

Koko doesn't share your real-time location. Others only see the location of a koko you choose to drop. Hidden kokos don't show a location.

No Tracking

Location is used to show nearby kokos and notify you on arrival, not to track your movements.

Just-in-Time Notifications

With your permission, Koko can notify you when you're close enough to a koko left for you, even when the app isn't open.

Here's what people think about Koko.

"Love it! This app is so cool! It's the perfect mix of fun and practicality. You can use it for reminders at locations to stay on top of things, or dropping fun messages for your friends. Plus, the design is really clean and easy to use, even if it's your first time. I've started using it every day, and have been having fun with my friends! Totally recommend checking it out! "

App Store Review

"This App is what I wanted to make. I've always wanted an app that suggests what I should do or order when I visit a place or restaurant. Since no such app existed, I kept the idea in my iPhone's memo app. However, Koko has exceeded my expectations."
