About this app
"6 + 9" is easy for me, but for some reason, I need some time to calculate "7 + 9"...
Don't you have such combinations of numbers that feel a little more difficult for you?
For me, the author of this app, the combinations containing 8 or 9 were difficult.
I felt it also hard to calculate the total price of products every time I went shopping.
So, I decided to develop this app, considering my own training too, and I actually improved my addition skills to some degree already by testing this app again and again while I was developing it.
I'm sure you'll also improve your own skills as I did!
I hope you enjoy the app as well as improving your mental addition ability.
HOW TO USE
Numbers are displayed one by one at specified time intervals.
Add up those numbers in your mind.
STAGES
There are 20 stages with a combination of 5 kinds of digits (1 to 5 digits) and 4 intervals (6, 3, 1 and 0.5 seconds).
The highest stage is 5 number of digits with 0.5-sec intervals.
You will be a real "expert" if you ever reach such a high level!
Each stage has its own name.
- 1 digit, 6-sec intervals: Shell stage
- 1 digit, 3-sec intervals: Prawn stage
- 1 digit, 1-sec intervals: Turtle stage
and so on...
EXPERT MEDALS AND LEVELS
You'll get an expert medal if you answer correctly 5 times in a row at a stage.

PRACTICE FUNCTION
You can switch the values by tapping on the forward/back buttons at your own pace.
Try as many times as you like until you get used to it, and you'll be good enough to feel the stage is much easier than before.

Make use of it to gain enough confidence to get the right answer within the time limitation.

- You can set one of preset theme colors, which makes it easier to distinguish a challenger from others on a device.
