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.

Tap the SPOT button. Camera opens. Frame it, shoot.Recognize
The app lines your photo up against every known sticker. Sure match → linked instantly. Close call → you confirm it with one tap.Map
Your spot appears on the world map. That sticker's story grows.Points
You see straight away what you earned and how you move on the leaderboard.How does the recognition work exactly?
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.
You don't spot alone.
Unless you want to. But the leaderboard keeps score.

Quick answers.
Does it cost anything?
No. No subscription, no paywall, no ads. Just free.
Do I need an account?
To spot, yes. Viewing sticker pages and profiles works without one.
How does the recognition work?
The app overlays distinctive points from your photo onto those of earlier finds. It works across different angles and changing light — not if the sticker is damaged beyond recognition or sitting in the dark.
What does the app do with my location?
We only use it to put your spot on the map. We don't store any location history beyond your spots.
Can I add my own stickers?
Yes. As a maker you register a sticker as a drop. Already in the app but not under your name yet? File a claim — an admin reviews it.
Does it work outside the Netherlands?
Yes. The map, leaderboards and recognition work worldwide.
