Help your child build confident multiplication recall through short, focused practice. Multiplication Bug is a free times-tables app for children ages 6–9. It uses spaced repetition to bring each fact back at expanding intervals—1, 3, 7, 14, 21, and 30 days—so practice focuses on facts that need attention. A CLEAR DAILY PATH • Daily Mission is the main learning path. Depending on progress, it can include a warm-up, new facts, targeted practice, and mixed review. • Practice reinforces facts your child has already encountered. • Evening Review offers a short review after 7 PM. BUILT FOR CHILDREN • Large, equal-size answer choices • Gentle feedback and encouraging celebrations • Plausible answer choices based on nearby multiplication facts • A pause option when recent answers show that practice is becoming difficult • Forgiving streaks with one grace day per week FOR PARENTS Create up to six child profiles, each with separate progress and streaks. A parental gate protects profile management, detailed progress, practice-intensity settings, privacy links, and store actions.

Parent-only native review and store or browser links are controlled by Apple, Google, or the selected browser, and the app sends no child profile or learning payload through those actions.
