Math By Heart vs Mentalator

Math By Heart is a fast-paced mental math game designed to build automatic recall through repetition. Practice addition, subtraction, multiplication, and division across multiple difficulty levels while tracking your progress. Instead of relying on tricks or calculators, you’ll develop true number fluency by solving carefully selected exercises that reinforce what you need most. Suitable for students, adults, and anyone who wants faster, more accurate mental arithmetic.

MOST calculation apps make you stop what you're doing, stare at the screen, and tap. Mentalator doesn't. Say your answer out loud and keep going — while you cook, fold laundry, work out, or take a walk. It's the only mental math trainer that fits into a life that's already full, instead of demanding a screen-only moment of its own. You can also use Mentalator the traditional way: looking at the screen and tapping your answers. HANDS-FREE, START TO FINISH Turn on Hands-Free mode and the whole session runs by voice: questions are read aloud, you answer aloud, and Mentalator listens and moves on. No taps required from start to finish. TWO WAYS TO TRAIN • Quick Mode: a question and four options — tap or say the answer, perfect for fast reps. • Chain Mode: a string of operations spoken one after another ("plus 7... times 2... OK") that you keep running in your head, then say the final result. This is where real mental math strength gets built — the kind you can't fake by scanning multiple-choice options. BUILD A HABIT, NOT JUST A SESSION Set up daily practice Plans with a time and days of the week, and get a gentle reminder when it's time to train — pick how many rounds of each mode, and let it run. TRACK REAL PROGRESS Your Profile shows response times by operation and by mode, accuracy over time, and a daily trend — so you can see mental math actually getting faster, not just guess. MAKE IT YOURS • Addition, subtraction, multiplication, division — choose which operations and how many digits. • Adjustable difficulty as you improve. • Voice available in English and Spanish. Whether you've got five minutes between tasks or want a daily ritual, Mentalator turns "dead time" into real practice — hands-free, voice-first, and built to fit around your day instead of interrupting it.
