Learn Perl is an Android application that provides a full offline manual of Perl. It includes Perl Tutorials, Perl Manual, Perl Reference, and all other relevant information. The application is developed by Thiyagaraaj M and is available for free.

The main features of Learn Perl are divided into three sections: Manual, Reference, and Modules. The Manual section includes an overview of Perl, tutorials, FAQs, history/changes, and license information. The Reference section covers language, functions, operators, special variables, pragmas, utilities, internals, and platform-specific information. Lastly, the Modules section contains an A to Z list of modules.

The application offers a comprehensive guide to Perl and is perfect for beginners who want to learn the language.
