Read full description

6×7 helps children master the multiplication table through ambient learning — a method based on cognitive science principles. Instead of boring drills, multiplication examples appear directly on the Home Screen through a widget. Each time the device is unlocked, the child sees an example for a split second. Over time, regular visual exposure builds passive recall — naturally and without pressure. The method combines: • Incidental learning — memory forms during everyday phone use • Spaced exposure — examples refresh regularly throughout the day • Semantic visual anchors — illustrations create meaningful memory connections • Multimodal encoding — consistent color + text + image strengthen retention • Adaptive prioritization — tricky examples appear more often • The testing effect — short quizzes activate recall and reinforce memory Quizzes are short and focused: • 15 random multiplication examples • Points based on speed and accuracy • Star system and progress tracking • Results stored locally on your device Designed for ages 7–12. No subscriptions. No ads. Works offline. Privacy: All data stays on your device. 6×7 does not collect personal information or use third-party tracking.
