Plakker recognizes stickers automatically and shows how far they travel. Shoot, spot, follow the trail.
Someone slapped that thing on a utility box in Rotterdam. Then nothing. No idea where it went. Until someone in Lisbon pulled out their camera.
On the back of a road sign in Prague. Under an escalator handrail in Tokyo. On a mailbox you’ve cycled past a hundred times. You see them. Shoot them. And the app tells you the story behind them.
Your drop is sitting on a shutter somewhere. Plakker sends you a notification the moment someone finds it — with a photo, a location and a pin on the map. That’s how you watch your work travel.
Tap the SPOT button. Camera opens. Frame it, shoot.
The app lines your photo up against every known sticker. Sure match → linked instantly. Close call → you confirm it with one tap.
Your spot appears on the world map. That sticker’s story grows.
You see straight away what you earned and how you move on the leaderboard.
Two steps: first a quick visual comparison ("do they look alike?"), then a precise check that overlays distinctive points in both photos. Lots of matches = definitely the same sticker — even at a different angle, different light or a bit of wear.
First spot: the corner of a doorframe in The Hague. Three weeks later: a utility box in Ghent. Two months later: somewhere in Osaka. The sticker page shows who found it, where, when — and how far apart the two most distant spots lie. Share it with one link. No account needed to look.
Unless you want to. But the leaderboard keeps score.
Spotters and makers. Weekly, monthly, all-time. Who’s climbing, who’s slipping, who came out of nowhere to top it.
Team up. Set a weekly goal. Chase it together. There’s a clan leaderboard — and a clanroom for your crew.
One sticker each week that sticks hardest. The most points that week = the glory. That’s all. But it feels big.
Find spotters by username or Instagram handle. Find stickers by name. One search field, live as you type.
Everything the app actually does, in one grid. No coming-soon vaporware.
Hit the SPOT button — the camera’s already open. Frame the sticker, shoot, done.
Your shot gets matched to known stickers: instant link, quick confirm, or a brand-new find.
The same sticker within ~15 metres won’t count twice. Anti-cheat, built in.

We only use it to put your spot on the map. We don’t store any location history beyond your spots.
