eSquirrel

eSquirrel is an educational quiz app that turns textbooks and courses into engaging quests. Each course is divided into quests of up to 10 questions; you earn acorns and advance from Bronze to Silver by answering all questions correctly. The app uses spaced repetition to repeat content right before you might forget it, turning study into long-term memory and making practice practical and fun.

In education mode, students tackle school and exam materials with high-quality content created by university lecturers and textbook authors. In business mode, eSquirrel enables mobile, offline-friendly training with ready-to-use materials on topics like data protection, first aid, and occupational safety. Quizzes are mobile-optimized, and a ranking shows top performers, motivating ongoing, independent and guided learning.
