How it works
1 · Album — open your book and mark what you own. Tap a slot, or hold and drag to paint a run. Own most of a team? Tap only the ones you're missing, then hit ⇄ Invert all 20 to flip the whole team. The layout mirrors each album spread, so match the pattern, not the numbers.
2 · Dupes — once a card is owned, a − 0 + strip appears on it: mark spare copies right there. The Dupes tab lists them A→Z and has a fast keyboard entry mode.
3 · Swap — copy your link and send it on WhatsApp. Paste a friend's link to instantly see who gives what. To sync your album to another device, copy your link and send it to yourself (e.g. via WhatsApp's "Note to self"), or tap the QR icon to scan it directly.
Team index
Quick entry (keyboard)
Same syntax, but here it marks cards, not spares. Press a, f, r or i anywhere to start typing. Space between stickers, double space to finish. ×N in add mode means N copies — the first fills the album, the rest become spares.
atpor5 4 6x2␣␣ → add POR 5, 4, and 6 with one spare
apor5 bel2 alg8␣␣ → add POR 5, BEL 2, ALG 8
ftpor5 6 8␣␣ → jump to Portugal, outline 5, 6, 8 — green owned, red missing
itpor␣␣ → invert all 20 of Portugal
How it works
Mark duplicates on the Album tab: every owned card shows a − 0 + strip. + adds a spare, − removes one, tapping the number clears back to zero. This tab lists your spares by team code, A→Z — the order you'd check against a friend's stack.
Quick entry is for typing with a keyboard. Start with a mode letter, separate stickers with a space, finish with a double space:
a add · f find · r remove · add t for team mode
apor5x2␣␣ → add POR 5, 2 spares
fpor5␣␣ → find POR 5 — owned? spares?
atpor5x2 6x4 20 15x2␣␣ → team mode: POR 5×2, 6×4, 20×1, 15×2
rpor5 6x2␣␣ → remove one POR 5 and two POR 6
