Your times tables – automatic at last. 1×1 Master is the times-tables trainer for adults. For everyone who briefly freezes when 7×8 or 6×9 comes up in everyday life – and finally wants to change that. Calm, respectful, and free of childish clutter. No brute-force memorization: 1×1 Master builds on the tables you already know and derives every hard fact from them. HOW IT WORKS • 2-minute sprint in three phases First estimate the magnitude, then recall the fact reliably, and finally apply it to everyday situations – short enough for every day. • Anchor hints Hard facts are derived from anchors you already know: 7×8 becomes 5×8 plus 2×8. Real understanding instead of blind drilling. • Spaced repetition Speed and accuracy decide when a fact comes back. You practice exactly what is still shaky – not what you mastered long ago. • Mastery matrix The 10×10 matrix shows at a glance which facts are automatic, which are in training, and which are still uncertain. • No-shame onboarding A calm check without right-or-wrong judgment determines your starting point. No pressure, no red pen. PRIVATE BY DESIGN • No accounts, no sign-up • No cloud – everything stays on your iPhone • No ads, no tracking • Works completely offline Times tables are not kid stuff. They are a foundation – and it is never too late to finally lay it properly.
