PigNote — Pig grows by feeding on memories left at places

Sticky notes on places

PigNote deals with messages tied to places. Stick a photo, a short text and stickers to the spot where you are standing, and a note (sticky note) stays there. Others can't see it by tapping a link — they have to actually walk into that spot. The author sets the opening radius anywhere from 30 to 500m; outside the radius you only see the author, the place name and that it is locked.

Time adds another layer. With a time capsule set, a note won't open before the chosen time even inside the radius, and public notes disappear from the map after 30 days by default. There are three visibility levels — public, friends only and only me — and you can choose for each note whether to allow reply notes.

Notes you find with the camera

A location alone only gets you as far as "somewhere in this alley". That is why there is Hide with an object. When writing, you take a photo of an object at that spot with the camera (picking from the gallery is blocked — it has to be an object here and now), and the reader, once inside the radius, has to point the camera at the same object to unlock it. You can leave a hint of up to 30 characters.

On Android, once the camera view recognizes the object, the message appears right on that spot. On devices without this feature and on the web and Toss, the app keeps looking while you point the camera and opens the note the same way. The server checks whether it is the same object. Object photos are processed in Seoul and never leave the country, and the check photo the reader takes is deleted right after the check.

Pig grows as you record

What keeps you coming back is not a ranking but a character. Leaving a note gives 20 XP, plus 15 XP for a place you have never been; discovering someone else's note gives 10 XP, reactions and comments 5 XP, and recording on consecutive days 10 XP. Pig eats this experience as 'memories' and grows.

There are up to 30 levels, and Pig's body changes through five stages: Baby Pig → Chubby Pig → Traveler Pig → Memory Collector → Master. Every level-up is designed to bring at least one visible change — memory fragments pile up at its feet, a mark appears on its body, or a wardrobe item such as a hat, bag or glasses unlocks. At levels 5, 10, 20 and 30, a transition plays where the fragments gather to preview the next stage's silhouette. There are 7 badges, and the room Pig lives in is decorated as it grows.

On your own or with friends

On your own it becomes a diary pinned to places; with friends it becomes a game of hiding notes for each other around the same neighborhood. Friendships require mutual approval through a friend code issued by the app, and there are block and report features. You can react to a note you found with 5 emotion stickers or leave a comment.

Anywhere, with peace of mind

PigNote runs in three places — the Android app · the web · a Toss mini-app — and all three are always updated together to the same version. You start with an anonymous account created per device, and linking a Google account or using a device link code ties your notes and Pig from all three into one account. If the connection drops, the app keeps working, and it catches up automatically when the connection is back.

Location is collected only while you use the app; it does not follow you in the background. The map shows only a position blurred to about 30m, and your real-time location is never shown to anyone. Photos have their location information removed before upload and are shown only to people whose access has been confirmed. Whether you are inside the radius is checked again by the server, so nobody can fake their location to open someone else's note from far away.
