There is no answer sheet for the abacus problem!
Calculating with a calculator is a hassle ...
At this time, the recommended app is "Abacus OCR".


With this app, you can easily find the answer by just taking a photo without repeatedly pressing the button on the calculator.
The image recognition technology (OCR) uses Google Vision API, so it can be read quickly and accurately.

In addition, multiplication and division can be calculated faster with a calculator than with image reading, so there is also a calculator function so you do not have to switch apps.

Adopting Google's voice recognition function "Android Speech Recognizer", it is also equipped with a function to automatically calculate the reading aloud.
When you tap the button and say "Wish you ~ 648 yen, 324 yen, pull 60 yen ...", the recognized content will be calculated and the answer will be displayed.


All of these features also support subtraction.
In addition, the image recognition function has been checked on the stage.
