Times tables, mental math, fractions & telling time, ad-free, for kids.
SumWise is a kids math app that turns times tables, mental math, fractions, and telling time into a daily habit your child actually looks forward to — no ads, no accounts, nothing ever sent off the device. Built for ages 7-11 (roughly grades 2-5 / UK Key Stage 2), SumWise adapts to exactly where each child is, question by question, so practice never feels too easy or too hard. Works fully offline, so it's a solid fit for the car, the classroom, or homeschool. WHAT'S INSIDE • Practice Tables — the times tables and their friends (addition, subtraction, multiplication, division), drilled untimed or against the clock • Arithmetic — bigger mental math: two-digit addition, friendly multiplication, and step-by-step confidence • Missing Number — fill in the gap (7 + ? = 15) to build algebraic thinking early • Visual Fractions — pie charts, bars, and shape splits so fractions make intuitive sense • Clock Practice — drag the hands on a real clock face, read analog times, and match digital clocks • Mastery Map & Rewards — earn coins with practice, unlock collectible stickers, and earn achievement badges WHY PARENTS & TEACHERS LOVE SUMWISE • 100% Ad-Free & Private: No pop-ups, no in-app upsells, no sign-up required. • Smart Adaptive Drill: The engine targets tricky facts (like 7×8 or 8×9) with spaced repetition. • Grown-up Overview: Clear report cards showing practice time, accuracy, and weak spots. • Multi-Child Support: Individual profiles for siblings on the same device. Turn math and clock practice into a fun, confident daily habit with SumWise!
