We have released an app for flash mental arithmetic practice from the Hokkaido University Abacus Circle!
It is equipped with various functions for widespread use from beginners to top-level athletes!
◆ You can freely set the number of digits, the number of units, and the number of seconds! !! ◆
・ The number of digits is from 1 to 9 digits
・ The number of mouths is from 3 to 100
-The number of seconds can be set in 0.01 second units.
You can challenge up to 1.00 seconds per 15 mouths at the fastest!
◆ Challenge the same problem many times with the replay function! !! ◆
It is equipped with a "replay function" that asks the exact same question as the previous question. Let's aim to improve your ability by challenging difficult problems many times!
◆ Equipped with a convenient actual measurement value display function for competition practice! !! ◆
The actual display time is displayed in 0.001 second units for the number of seconds set in 0.01 second units. As a result, even top-level athletes competing for 0.01 seconds can use it with confidence.
* Until now, it was said that the reliability was low in 0.01 second units due to the limitation of the refresh rate of smartphones, but by displaying the measured value, it can be used for practice with extremely high accuracy.
◆ Equipped with multiple functions that are convenient for practice! !! ◆
You can choose from 3 types of fonts! (Abacus font, Mincho font, Gothic font)
Character size adjustment (large / medium / small)
Sound ON / OFF setting
Comma (,) ON / OFF setting (4 digits or more)
Recommended for people like this! !!

・ Those who are learning abacus and want to use it for daily practice
・ Those who are aiming to win a prize in the competition
* Depending on the specifications and memory of the terminal, the set number of seconds and the measured number of seconds may differ significantly. In such a case, you can improve it by disabling the background app or restarting the device.
* Even if used correctly, the set number of seconds and the measured number of seconds may deviate by about 0.03 seconds. Please note that this is an error due to the refresh rate of the smartphone.
〇 All functions can be used by purchasing "Flash Mental Calculation pro +". There are no ads or additional charges. In addition, all the functions of the app can be used even when offline.
