Practice vs Badger

Mental arithmetic isn't something you learn once — it's something you build through repetition. This app gives you a near-infinite supply of problems, letting you practice until any calculation feels effortless. Train with targeted drills for addition, subtraction, multiplication, and division. Focus on the operations that trip you up most, and go from uncertain to fluent. Built-in difficulty presets mean you can open the app and start immediately — no setup required. When you're ready to fine-tune, full customization is available: toggle carrying for addition, borrowing for subtraction, and set the exact number ranges for multiplication and division to suit your current skill level. The interface supports both light and dark mode, so it's comfortable to use anytime, anywhere. Multi-language support removes any language barrier to practice.

Badger is daily math practice for kids — short, focused sittings that build real fluency, from first counting to times tables and beyond. KIDS WRITE, THEY DON'T JUST TAP Answers are written by hand, right on the screen, and recognized on the device — practicing digits and sums the way school does, not multiple-choice guessing. A TRAIL OF OVER 150 SKILLS Counting, dice and dominoes, comparisons, addition, subtraction, times tables, division, and more — arranged as a trail that meets each child where they are. A gentle placement finds the right starting point; skills come due for review just when practice would help most; every sitting is a few focused minutes, not a marathon. PRIVATE BY DESIGN No accounts. No ads. No tracking. No in-app purchases. Your child's handwriting, answers and progress never leave the device — recognition runs entirely on it, and we have no servers to send anything to. (The handwriting component is made by Google and reports anonymous technical diagnostics about itself to Google; our privacy policy says exactly what.) BUILT FOR FAMILIES Several children can share one device, each with their own trail and progress. A grown-ups' area behind a parent gate shows progress at a glance — medals, minutes practiced, and the facts each child knows — and can share a report as a PDF when you choose to. IN YOUR LANGUAGE English, French, Spanish, Portuguese, Italian, and Amharic. We're parents building apps for our own children — encouraging the daily math practice that lays foundations for life.
