I like it, you can always exercise your mind as you work out in the gym, it makes you fast with your mind, when it comes in decision-making or other fields in life it will always help you to be fast with your mind, I use it to keep me fast, you also feel powerful when you are quick and right with maths. I recommend it, simple and effective.

Best way to improve your mental maths. But if there is an option to hide timer, it would be way better. The blinking timer distracts mental process. < following is attached on 09. 10. 21 > As soon as updating I found it terrible. So I uninstalled and reinstalled the previous version with apk. so I should minus 2 stars.

Solid free app Appreciated the ability to sharpen my quite rusty mental math. I wish there was a free text mode to force me not to look at the options. Also the leaderboard seems to not take anything but time into consideration
