Frequently Asked Questions
Everything you need to know about Matics, mental math active recall, and feature capabilities.
What is Matics and how does it compare to other math apps?
Matics (renamed from Mathzen) is a dedicated mental math workout and active recall training application. Unlike apps that only display static formula sheets or basic quizzes, Matics forces your brain to actively retrieve information through scientifically proven Active Recall and Spaced Repetition. This builds long-term neural memory so formulas and calculation shortcuts become instinctive reflexes under exam pressure.
How do the 3 scientific recall modes work in Matics?
Matics structures learning through three progression phases:
- Guided Recall: Learn new formulas step-by-step with progressive reveals to understand the underlying logic.
- Active Recall: View partial equations, retrieve the missing values from memory, and tap to check. Target your personal weak spots with self-marking.
- Forced Recall (Exam Mode): Recreate real test conditions with countdown timers and answer construction under time pressure.
How does the Hands-Free Voice Recognition mode work?
Matics includes a seamless speech recognition mode. Simply tap the microphone icon and speak your answers aloud in English (e.g. saying "seventeen", "forty-nine", or "one half"). This allows you to practice mental arithmetic completely hands-free while walking, commuting, or multitasking.
Which mathematical topics, formulas, and levels are covered?
Matics covers a comprehensive curriculum from middle school basics to university exam preparation, including: Mental Arithmetic (addition, subtraction, multiplication tables 1-30, rapid division shortcuts), Squares & Cubes (1-100 squares, 1-20 cubes, square/cube roots), Algebra Identities (quadratic equations, factoring tricks, 3-variable expansions), Trigonometry (Sin, Cos, Tan values, reciprocal identities, unit circle angles 0° to 180°), Percentages & Fractions conversion charts, and 2D & 3D Geometry formulas.
Which exams and tests is Matics designed for?
Matics builds the calculation speed and accuracy required for major global exams including SAT, ACT, AP Calculus, GCSE, A-Levels, GRE Quantitative, GMAT, JEE (Mains & Advanced), SPI & Japanese web aptitude tests, Russian OGE & EGE, French Baccalauréat, and Civil Service tests.
Is Matics completely offline and private?
Yes. Matics operates 100% offline with zero internet connection required. It does not require any account creation or personal data collection. Your practice metrics and mastery statistics remain completely private on your device.
