Blitzcalc: Mental Math

371 skills, one adaptive engine. Every question is generated fresh, so you learn the method instead of memorising a deck.

Blitzcalc trains the way you actually get faster at mental maths: one technique at a time, measured, and adapted to you.

QUESTIONS MADE FRESH, NEVER MEMORISED There is no deck. Every question is generated, so the numbers change while the skill stays the same - the only way to know you have really learned it.

IT MEASURES, IT DOESN'T ASK A short adaptive check finds your level from how you actually answer, including how long you take. No self-assessment, no picking a grade and hoping.

371 SKILLS ACROSS 12 PACKS Whole numbers, fractions, decimals, percentages, powers and roots, algebra, measurement, probability and more - sequenced so each one rests on the last.

THE MISTAKE LAB Blitzcalc names the mistake behind your errors, not just which questions you got wrong. Train a named pattern and it tracks whether the fix actually held a day and three days later.

MASTER CLASSES A class takes a single technique - splitting instead of carrying, say - and teaches it on purpose: the method first, then guided practice, then speed.

THE BLITZ EXAM (Pro) Every other screen adapts to you, which is why none of them can grade you. The Blitz Exam gives that up on purpose: a fixed 20-question paper across everything you have practised, scored out of 100 - and kept, so a single number becomes a trend you can watch climb.

BLITZCALC PRO The Blitz Exam, the Diagnosis (the one mistake behind most of your errors, across every topic), Review Sets with a goal and an exam date, full manual mode over all 371 skills, unlimited practice, and the advanced statistics.

Free to use every day. Pro is a subscription; there is a free trial and you can cancel any time.
