v1.0.0 Major

OneZeroTwo went public. Pricing was rebuilt and verified, search stopped mistaking a Pokémon for a set, the site became readable to search engines and AI assistants, and Pro members got 102 colour themes, one per Base Set card.

On 10 September 2026 OneZeroTwo went live at onezerotwo.app. What a visitor got on day one: card search and a value for anyone, signed in or not; a free account for a synced collection, a watchlist and photo scans; Plus for more of each; and Pro for the dealer tools. Every number on the site came with the caveat it had always carried in the app: an estimate from public market data, labelled, never a guarantee.

The week before launch was a scramble, and it is worth saying so. Pricing was rebuilt and verified: every price is checked to be the exact card asked for before it is shown, and kept so the next look is instant. At the same time the search box was found reading charizard as a set code and hiding the cards people type most; that went in the same push.

The other half of launch day was invisible in a browser. The deployed site served 167 characters of text a crawler could read, because everything a person sees is painted by the app, and the robots and sitemap files answered with the app's shell. Search engines and the AI assistants people ask about card values saw nothing. So About, How it works, the FAQ, the guides and the set pages became real pages, with a sitemap, a robots file that welcomes the named AI crawlers, and an llms.txt stating both accuracy figures with their scopes. Expectations were written down honestly: readable that day, indexed in weeks, ranked in months.

And the themes. OneZeroTwo is named for the 102 cards of the original Base Set, so Pro members got 102 palettes, one per card, that re-skin the whole app on every device the account signs in on. The default look stayed the dark one; a theme changes the accent and the ground and nothing that carries a number or a verdict.
