Quick Math vs Calcul Éclair

Build confident mental arithmetic with short, adaptive practice for kids, adults, and seniors. Quick Math works on iPhone and iPad with no account or ads. ADAPTIVE PRACTICE Choose a Kid, Adult, or Senior profile. Quick Math selects the operation mix and difficulty from the profile, stage, and recent accuracy, then gives extra weight to operations that need more practice. Core arithmetic includes addition, subtraction, multiplication, and exact whole-number division. EIGHT WAYS TO PRACTICE • Practice: an open-ended adaptive session with answer feedback. • Rush: start with 60 seconds; each correct answer adds two seconds. • Builder: arrange number and operation tiles from left to right to reach a target. • Sprint: finish a fixed set of questions and track score and total time. • Speed Test: answer as many questions as you can within a fixed time. • Quant Drills: practise sequences, probability, and numerical reasoning. • Hundred Grid: fill a timed multiplication board. • Gauntlet: face harder questions as the run continues. LEARN FROM MISSES A mistake or a slow answer can surface the mental-math technique that fits it. The technique is named for everyone; Quick Math Pro adds the full explanation and a worked example. PROGRESS FOR THE WHOLE FAMILY Create separate local profiles, each with its own stage, scores, streaks, accuracy, and per-operation breakdown. Compare profiles on a same-device Family Board. Optional reminders and widgets help keep practice visible. PRIVATE BY DESIGN Your practice history stays on your device. Quick Math has no account, ads, analytics, or third-party tracking. The weekly note for parents is compiled on the device from that history. SUBSCRIPTION AND YOUR DATA New practice requires Quick Math Pro, offered as a monthly or annual auto-renewable subscription. Eligible new subscribers may receive a 3-day free trial; eligibility, local price and terms appear before purchase. If your subscription ends, you can still view, export or delete every profile, stat, streak and answer without a subscription. Earlier one-time purchasers retain Pro access through Restore Purchases; the lifetime purchase is no longer offered for sale.
