Oak is a free iPhone app developed by Lingo AB. It falls under the Lifestyle category with a subcategory of Food & Drink. Oak allows users to experience wine tasting from the comfort of their own homes. The app offers a selection of curated wines, which users can choose from. Once a wine is selected, the app provides information on where to find that specific wine at Systembolaget, the Swedish alcohol retailing monopoly. Users can then invite friends over for a wine tasting session and scan the bottle to start the tasting experience.

Oak's wine tastings are curated by experts in the field, including Ellen Franzén, the Swedish Sommelier Champion and silver medalist in the Nordic Championships. The app aims to provide a convenient and educational wine tasting experience for users.

Oak is a completely free app. For any feedback or inquiries, users can reach out to
