Quiss

Quiss is a notification-first daily quiz app built for focused learning and friendly competition. Choose one to three topics and your active hours, then receive up to three short quizzes a day. Each daily quiz stays open for 15 minutes, keeping every session clear and intentional. Build a streak by answering at least two daily quizzes, or use Training when you want to practise on demand. Topic Mastery tracks progress only in the topics you currently choose, so your profile reflects what you are actively learning. Open Duels to challenge friends, find an instant opponent, play a revenge match, or enter a Trick or Powers room. Powers can hide answers in mud, freeze them in ice, let bugs eat a few letters, or lock an answer with a bomb for 2 seconds. Instant duels favour topics both players share; when there is no overlap, Quiss creates a balanced mix from both players' interests. Social brings together rankings, friends, requests, and a categorized History for daily quizzes, Training, challenges, revenge matches, instant duels, Trick games, and Powers games. A lightweight Quiss account is created on first launch. You can later connect Google or Apple in Profile to open the same player on another device. Progress stays with that player until you delete it from Profile with Delete account. Quiss is 13+. Non-personalized ads may appear at app open, before the first Training pack of the day, when creating a Trick room or a Powers room, or when starting revenge play. Notifications are optional.
