Learn by Heart is a free Android application developed by Bogems under the Education & Reference category. The application is designed to help users memorize a text or poem by gradually hiding words in it.

The application works by allowing the user to upload a text or poem to the application. The user then reads the text 2-3 times, trying to remember it. As the user progresses, the application increases the difficulty level by hiding some words, making it harder for the user to remember the entire text.

As the user continues to use the application, the difficulty level increases, and almost all the words in the text are hidden. This makes it easier for the user to remember the entire text.

Overall, Learn by Heart is a useful application for anyone who wants to memorize a text or poem. It is easy to use and can be customized to suit the user's needs.
