Cardslot

What Cardslot is

Cardslot is an Android and iOS app for tracking Nintendo Switch and Switch 2 eShop prices, sorting deals, and receiving sale alerts. Its default deal score considers discount percentage, regular price, and eShop sales rank. The app reads public eShop data several times a day and notes that the price shown by the eShop at purchase is authoritative. Coverage spans fourteen storefronts: ten European markets plus the United States, Canada, Mexico, and Brazil. Tracked-game alerts cover price drops and a reminder the day before a sale ends, with a maximum of one alert per day between 9:00 and 21:00 local time. Alerts are best-effort and are not guaranteed to arrive on time. A sale calendar displays end times and a histogram of deals ending over the next fifteen days. The free version includes search, the full deal list, sorting, and one tracked game. Full version costs $3.99, paid once and removes that limit while adding price history and more filters. Watchlists are stored on the device and server under a random installation identifier.
