Potto.

Leave a few words on the map. Potto lets you drop a "Poto" — a message up to 31 characters — onto a world map split into 150-meter squares. Your hometown. A street that matters. The spot you'll want to remember. It's not about shouting. It's about leaving a small mark that you were here. ■ The Rules 【One per square】 Each 150-meter square holds just one Poto. If someone got there first, it's theirs. That's what makes placing yours mean something. 【Three a day】 You get three Potos per day. Not a place to broadcast — a place for the words worth keeping. 【Pick from our colors】 Choose a color for each Poto from a curated set. You might cross paths with someone who picked the same one. ■ What's not here ・Like counts ・Algorithmic recommendations ・Anything that ranks you against others ■ What you can do ・Drop a Poto on the public map, or your own private one ・Find other people's Potos around you ・Hit shuffle to land on a random Poto ・Browse the latest Potos in the feed ■ Why we built this Social media can be quieter. There should be at least one place where it's fine if no one's watching. Leaving something on a map, in your own color, is a quiet way of saying: I was here. Pick your color. Find your square. Leave a few words. ■ Support Reach us on X: @potto_it
