About this app
Help your child master multiplication — and actually remember it.
Multiplication Bug is a free multiplication learning app for children ages 6–9, built on spaced repetition science. Your child reviews each fact at precisely timed intervals — 1, 3, 7, 14, 21, and 30 days — moving knowledge from short-term memory into lasting recall. No random drilling. No anxious speed tests. Just effective, science-backed learning.
WHY SPACED REPETITION WORKS FOR TIMES TABLES
Most multiplication apps quiz facts randomly or rely on speed drills. Research shows that spaced repetition produces dramatically stronger long-term memory. Multiplication Bug tracks every fact individually, scheduling reviews exactly when your child needs them.
THREE SESSION TYPES FOR DAILY LEARNING
Daily Mission
The core learning path. Each session introduces new multiplication facts from the current times table, then reinforces them through targeted drills and mixed review. The app advances your child through tables 2 to 9 automatically as they demonstrate mastery.
Practice
Additional multiplication practice drawing from all tables your child has started. Available anytime for reinforcement between Daily Missions.
Evening Review
A short review of 3–5 multiplication questions available after 7 PM. Research shows that reviewing material before sleep strengthens memory consolidation. This unique feature helps your child retain times tables more effectively.
DESIGNED FOR REAL CHILDREN
Multiplication Bug is built around how children actually learn, not how adults imagine they should:
• Smart answer choices — Wrong answers come from neighboring times tables (like 48 and 63 alongside 56 for 7×8), helping your child distinguish commonly confused facts.
• Frustration detection — If your child is struggling, the app gently pauses with encouragement instead of pushing through.
• Growth mindset feedback — Wrong answers appear in warm orange, never harsh red. Encouragement says "Good Effort!" because effort matters more than perfection at this age.
• Forgiving streaks — One grace day per calendar week means a single missed day does not break your child's streak. A personal-best display turns any gap into motivation, not discouragement.
• Earned mastery — Facts require 3 correct answers in a row, 85% accuracy over 6+ attempts, and sub-3-second responses. This ensures genuine fluency, not lucky guessing.
FAMILY-FRIENDLY FEATURES
• Up to 6 child profiles, each with independent multiplication progress and streaks
• Parental gate protects settings with a number-as-words challenge
• Four practice intensity tiers let parents control session frequency
• Bonus sessions and cooldown bypass available behind parental gate
• Progress dashboard shows accuracy heatmaps and table-by-table mastery
PRIVACY AND SAFETY
All data stays on your device. No accounts, no personal data collection, no ads, no analytics, no internet needed. Fully compliant with COPPA and GDPR. Your child's learning stays completely private.
15 LANGUAGES
English, German, Spanish, French, Italian, Dutch, Portuguese, Romanian, Polish, Turkish, Belarusian, Russian, Ukrainian, Indonesian, and Vietnamese. The entire interface — including the parental gate — is fully translated.
WHAT YOUR CHILD WILL LEARN
• All multiplication tables from 2 through 9 (80 facts)
• Quick recall of times tables through spaced repetition
• Confidence distinguishing between similar multiplication answers
• Healthy learning habits through daily practice streaks
COMPLETELY FREE — NO CATCHES
Every feature described above is included for free. There are no ads, no in-app purchases, no premium tier, and no trial that expires. Multiplication Bug is a complete times tables learning tool at no cost.
