Scrolling that makes you smarter. MathMe is a mental math trainer built like a feed. One question per screen: tap the answer, swipe to the next. The minutes that would have gone to another feed go to a skill you keep for life. NEW: A MENTAL MATH COURSE 39 topics in 7 chapters β€” Numeration, Whole Numbers, Divisibility, Common Fractions, Decimals, Ratios and Proportions, Percentages β€” with 1,334 practice questions. Each topic teaches one technique. Γ—5 is Γ—10 Γ· 2. Γ—25 is Γ—100 Γ· 4. You see how the trick works, why it is worth knowing and where people usually slip β€” then practice it right away in a feed you scroll through. The starter topics are free. The full course is part of MathMe Pro. SWIPE: YOUR FEED, BUT IT’S MATH A timer on every question, a swipe to get the next one. Difficulty is matched to your skill level. Two hints help when it gets hard: 50/50 removes two wrong options, and the Shield protects you from your next wrong answer. DUEL: 1 ON 1 IN REAL TIME In Duel you create a room and send the code to a friend, join a room by code, or let the app find an opponent. 10 rounds, one winner. Want to warm up first? Train against a bot β€” it does not affect your rating. FOUR MORE WAYS TO TRAIN β€’ Practice β€” pick the operations (+ βˆ’ Γ— Γ·) and the difficulty: Easy, Medium, Hard, Expert, or Random. No pressure. β€’ Arcade β€” 3 lives, a combo multiplier for consecutive correct answers, and difficulty that rises every 5 correct answers. β€’ Survival β€” your health bar keeps draining; 5 types of power-ups help you last longer. β€’ Time Attack β€” score as much as you can before the clock runs out. Fast answers multiply your points.

About

Kopfrechnen Trainer

Features
Read full description

Kopfrechnen Trainer is a German-language app. Every problem is read aloud in German and is not shown on screen while the child works on it. There is no English version, no English audio and no text mode. The app suits children who do their maths in German: at a Grundschule, Volksschule or Primarschule in Germany, Austria or Switzerland, at a German-language school abroad, or in a bilingual family that wants German maths practice at home. Your child needs to understand spoken German numbers and short German sentences to use it. WHY THE PROBLEMS ARE SPOKEN Teachers in German-speaking primary schools dictate mental-arithmetic problems and the children write down only the answer. This app does the same. The child hears "sieben mal acht", holds the numbers in their head, works it out and types the result. Nothing to read off the screen, nothing to copy. The audio can be replayed as often as needed. If the child is stuck, a hint names the strategy, and the solution can be shown. WHAT YOUR CHILD PRACTISES β€’ Addition, subtraction, multiplication and division (plus, minus, mal, geteilt) β€’ Numbers up to 20, 100, 1,000 and 10,000 β€’ The times tables (Einmaleins) and multiplication beyond them β€’ Division with remainder and short word problems (Sachaufgaben), also spoken in German β€’ Seven levels, from the end of Klasse 1 to Klasse 4 in the German school system, roughly ages 7 to 10 β€’ Over 2,400 problems, each with a strategy hint and a solution STRATEGIES, NAMED AS IN SCHOOL The hints use the strategy names children hear in Bavarian primary schools: Verdoppeln, Tauschaufgaben, Hilfsaufgaben, Kernaufgaben, Umkehraufgaben, Stellenweise rechnen, Dividieren mit Rest and more. The levels and strategies are our own alignment with the Bavarian LehrplanPLUS for primary mathematics. This is not an official review or endorsement by any education authority. FOR PARENTS β€’ Several child profiles on one device, useful for siblings β€’ Parent area with progress per child, per level and per strategy, behind a simple parental gate β€’ CSV export and import of results β€’ Works completely offline, no account, no sign-up β€’ No advertising, no tracking, no analytics, no cloud: all data stays on the device PRICE The first 50 problems are free. After that an optional auto-renewing yearly subscription (Premium) unlocks unlimited practice, with Family Sharing for the devices in your Apple Family. The price is shown in the app and on this page. WHO MADE IT Kopfrechnen Trainer was designed by two Bavarian primary-school brothers together with their parents, starting from the mental-arithmetic dictation they knew from their own classroom. It is a small, quiet app: no reward games, no advertising, just listening and calculating. Please note once more: the interface, the audio and the word problems are all in German. If you are looking for an English-language maths app, this is not it. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
