About this app

Hone Math helps you actually get good at mental math — not with flashcards and gold stars, but by teaching you the method behind every skill, then letting you practice until it clicks. Built for grown-ups who want to feel confident with numbers: splitting a bill, checking a total, working out a discount in your head. Calm, editorial design. No cartoons, no ads. LEARN THE METHOD Every skill starts with the trick — make ten, doubles, multiplying by nine, working out a percentage. See how it works on a clear example, then practice. Miss one and the method comes right back, so you can review it before continuing. MASTER ONE SKILL AT A TIME A clear path from the times tables through addition, subtraction, multiplication tricks, division, percentages, and everyday word problems. Watch each skill move from new to mastered. PLAY YOUR WAY TO NUMBER SENSE Three number puzzles that make practice feel like a game: - Make Ten — clear the board by finding number bonds - Cross-Math — fill a math crossword, from 3x3 up to 10x10 - Construct — build the target number from a tray of tiles Each mode generates fresh puzzles. Hone Pro includes unlimited puzzles. A CALM DAILY HABIT A short Daily Workout keeps your streak alive in about three minutes. Small and consistent beats long and rare. HONE PRO After onboarding, a Hone Pro subscription is required. Choose a monthly or annual plan; eligible new subscribers receive a 3-day free trial with either plan.

WHY HONE - Learn the method, don't just drill - Puzzles that build real number sense - Practice works offline; your practice progress stays on your device - No ads - Hone Pro lets you choose light or dark Learn the method.
