## Description

With Brain Injection, you can efficiently and reliably memorize the knowledge you want to learn.<br>The usage is simple: just register the questions and answers once, and then rely on the app&#39;s notifications to solve the questions repeatedly.<br><br>【Features】<br>・Simple functionality makes it easy to learn and use quickly<br>・Notifications arrive at the optimal timing for memorization based on the forgetting curve<br>・Images of questions and answers can be zoomed in and out, so even images with small text can be used<br><br>【Efficient Usage】<br>Instead of spending time creating questions, spend more time solving them for a faster path to memorization.<br>Since creating questions and answers with text input is inefficient, it is recommended to take pictures of textbooks or notes to create questions.<br><br>Leave the management of review time to the app and enjoy efficient learning!
