A free app for Android, by Governo do Brasil.

SEI is a system that allows the public to access information and make changes to it. It is a modern tool that can be used in public institutions and organizations, as well as in the private sector. It was developed with the objective of making the access to information in electronic format easier and more secure.

SEI provides the public with a convenient way to view and manage electronic documents, which can be signed, tracked, or changed. The system is user-friendly, which means that even if you have no knowledge of using the internet or electronic documents, you can still use SEI. You will only need to download the application, which will then be ready to use right away.
