Hobby Alpha is a sports card research and collection management tool. It lets users scan cards, review card details, and research available sold comparisons alongside clearly labeled modeled price estimates. Its market analysis includes buy, hold, or sell verdicts and player level outlooks based on signals such as news, momentum, and liquidity. These outlooks provide market context rather than an exact valuation for an individual card. Reported sales comparisons are not independently verified as exact card matches, and modeled estimates are not guaranteed selling prices. Users can organize cards into digital display cases that can be shared and monitor collection values over time. Other features include player research across football, basketball, baseball, hockey, and soccer, sealed product and break analysis, and, with Pro, portfolio guidance, alerts, and growth projections. A typical workflow is to scan a card, review available sales information and analysis, then save and organize it in a collection. The service offers a free plan with up to five scans per day and a Pro plan for $12 per month with up to 100 scans per day and additional tools. Hobby Alpha runs on the web as a responsive progressive web app. On mobile, it can be installed from Safari on iOS or Chrome on Android; it is not offered as a separate App Store or Google Play download.
