Mannu is a mobile application designed to provide farmers with basic information about the land and soil they are cultivating. The application is a part of the Mannu project, which is a research-based effort to improve the farming community's knowledge about the state of the land and to help farmers make informed decisions about the crops they want to grow and their farming methods.

The application has two main sections. The first section provides information about the land and the crops the farmers are cultivating. The second section contains the most important information, which includes the soil test results, the crop requirements, and the weather conditions.
