Comments on Mental Math - Train your Brain for Android

★★★★★ Aadil Kamran · Apr 11, 2020
This is a great app for improving mental math. It makes you feel like a genius when you solve some of the harder problems.
★★★★★ ʏᴏᴜʀ ᴅᴀɪʟʏ ꜱᴘʏ · Jan 15, 2021
Really great, although I haven't finished the practice, I wish I can go back to previous tips, maybe I'll get there when I finish all of these, great variety of tips, im just going to uninstall then install again to be able to screenshot all the tips for now
★★★★☆ Rashmi Gupta · Jan 23, 2021
I AM VERY MUCH IMPRESSED WITH THE APP. ITS TIME FEATURE IS REALLY CHALLENGING... REALLY A BRAIN EXERCISE... THERE IS ONLY ONE THING THAT I FEEL COULD BE BETTER IF... NUMPAD/NUMERIC KEYS WERE BIT LARGER OR FAR SPACED. IT WILL MAKE USER INTERFACE BIT EASY AND FASTER. BUT ON THE OTHER HAND CURRENT NUMPAD SETTING ALSO PROVIDE ADDITIONAL CONSCIOUS AND CAUTIOUS BRAIN TRAINING . ITS LIKE DOUBLE BRAIN TRAIN... WHERE ONE TRIES TO QUICKLY ENTER ANSWER YET REMAIN CAUTIOUS TO NOT PRESS OTHER KEYS .GOOD
★☆☆☆☆ Craig Jones · May 28, 2021
Gives you random operations and number of digits. Dropped. Lacks basic obvious functions.
★★☆☆☆ Multiple Sources · Dec 15, 2020
It's ok but even on easy mode there isn't enough time to do the hard ones e.g. 571×408 I hope I'm not alone in thinking 80 seconds isn't enough for this. Meanwhile, I have 20 seconds to calculate 85-85. A useful app but better timings would help for sure.
