1×1 Master

Features
Read full description

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.

Read full description

SumSum Party is a math game that turns mental-math practice and brain training into a party, with a little blue frog named Ribbit. Every answer is a small celebration: tap a digit and Ribbit rolls it into the equation with a flick of his tongue. Keep going and the music speeds up, the lights, confetti and little fans join in, until the whole stage bursts. Get one wrong? Nothing is taken away. It just breaks your combo, and Ribbit is right there to try again. WHAT YOU PRACTICE - From sums within 10 to two-digit arithmetic, times tables, column addition, subtraction, multiplication and division, decimals, fractions, factors and multiples, estimation, percentages, ratios and simple equations - 49 skills across 5 tracks and 6 stages, with a skill tree, 1-5 stars, and skills that "rust" to remind you to review - Placement, level practice, single-skill practice, a review of mistakes, and a timed bonus round called Encore. Each round takes a few minutes A REASON TO COME BACK - Daily tasks, login stickers, a calendar and lotus-leaf make-ups - About 230 trophies and 48 cosmetic collectibles: backgrounds, stamps, confetti, music, Ribbit's outfits and colors, buddies and finales - Rewards are cosmetic only. You always get them: no loot boxes, and nothing you can buy QUIET AND CLEAN - Works fully offline. No account, no ads, no subscription, and no personal data collected - 20 languages, on iPhone and iPad - Optional daily reminder, only if you turn it on PRICING - Free to download.
