How does Stickerradar work?

Stickerradar helps you finish your sticker album without buying blind. You track the stickers you own, the app flags your duplicates, and it shows you exactly which of your spares your friends still need — so you can trade your way to a complete collection. Here is how the pieces fit together.

Track your collection

Pick your album and tap the numbers you own — or point your camera at a pile and let Stickerradar scan them in. Your completion updates instantly, for the whole album and for every section, so you always know what is left to find.

Spot your spares

Every sticker you own more than once is a spare — a duplicate you can trade away. Stickerradar gives each one a clear spare-count badge, so you never have to guess which stickers are free to swap.

Friends — trade with people you know

Trading happens between people you actually know. Add a friend with their invite code, by scanning their QR code, or by their @handle. Once you are connected, your spares and the stickers you still need can be matched against each other.

You stay in control: you only trade with friends you have added, and you can remove a friend at any time. There are no strangers and no public marketplace.

Radars — pool your spares with a circle

A Radar is a small circle of friends who pool their spares so the duplicates you own can meet the stickers your friends still need. Create a Radar, invite a few friends into it, and Stickerradar continuously scans everyone’s spares and missing stickers for trade matches.

When a friend in your Radar has a sticker you are missing — and you have a spare they need — you both get a notification. No refreshing, no spreadsheets: the app tells you the moment a trade becomes possible.

Make the trade

Open a match to see who has what, agree on the swap, and mark the stickers as traded once you have exchanged them. Your collection and spare counts update, your completion climbs, and the next match is already being found.

That is the whole loop: track → spot spares → connect with friends → match in a Radar → trade. The more friends you add and the more Radars you join, the faster the album fills in.
