まるつけ is an Android application developed by iScope Inc. that aims to support the process of checking math homework and worksheet answers. This app allows users to simply take a photo of their answers, and it will automatically recognize the written equations and solutions, checking if the calculations are correct.

With まるつけ, users can efficiently and automatically mark their answers, even when dealing with a large number of worksheets. This makes the daily task of checking answers much easier and more enjoyable. It primarily focuses on elementary school-level math problems.

The app is capable of recognizing handwritten solutions, but there may be cases where it misinterprets the handwriting. Therefore, it is important to note that まるつけ is designed to support the marking process and not always provide 100% accurate recognition.

The types of answers that can be recognized by まるつけ include addition, subtraction, division, multiplication, multiplication products, and calculations involving fractions.
