Duplicate Stickers Sorted by National Team: Find Your Spares Fast

What counts as a duplicate in Onzi

Every time you mark a sticker you already own, the extra copy lands in your duplicates. The first one goes in your album; the second and beyond become spares, the ones you put up for trade.

There is nothing extra to do for this to happen. As you scan or add stickers day to day, the app keeps a running count of how many you hold of each number and sets the surplus aside on its own.

Everything grouped by team

Instead of one long, jumbled list, your duplicates are gathered by national team. Each side shows the stickers you have spare from it, all in one spot.

This mirrors how most trades actually go down: you are almost always after stickers from a specific team. With everything split by country, you can jump straight to the one you need.

• Each team shows only the stickers you have duplicates of.
• The number of extra copies of each one is shown right beside it.
• Teams with no spares stay out of your way.

Check it before every trade

When someone asks "what do you have from Argentina?" or "got any Brazil spares?", this is where you answer in seconds. Open your duplicates, find the team, and the list is right there.

It is just as handy for prepping before you meet up. Skim your spares team by team and you show up already knowing exactly what you can offer.

• Check your spares from one team fast before you offer a trade.
• Match what you have spare against what a friend still needs.
• Pair it with the QR Code trade session to surface the perfect matches on the spot.

Always current and fully offline

The by-team grouping keeps itself up to date. Traded a duplicate away and removed the extra copy? It drops out of your spares right away. Pulled another of that same sticker? It joins the count instantly.

And because everything lives on your phone, your duplicates stay organized with no signal at all, in the corner shop, at school, or at a friend's place. No account, no sign-up, no fuss.
