Kraepelin Training

The Kraepelin test is:
Add adjacent numbers, and answer the last digit.
For example, if the numbers in a row are 3 and 9, 3+9=12, the correct answer is 2.
Kraepelin consists of 15 minuites in the first half, 5 minuites rest, and 15 minuits in the second half.
We recommend 15 sets of 60s for practical training with our App.

Features:
Custom operator mode
You can train with the combination of「+」,「-」, and「×」. (Not only for the Kraepelin preparation, but for brain training or calculation practice.)
