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 room. 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, and Trick games.

A lightweight Quiss account is created on first launch on this device. There is no Apple, Google, or email sign-in. Progress stays with that account until you delete it from Profile with Reset this device.

Quiss is 13+. Non-personalized ads may appear at app open or before Training. Notifications are optional.
