Librusek is an alternative app for Librus Synergia, a popular school management system in Poland. It is designed to be more user-friendly and modern than the original website.
- Logging in with Synergia: Librusek doesn't require you to create a Librus account, instead opting for the ability to login with your pre-existing Synergia account created for you by your school administrator.
- Landing page: All your account information, like your name, school, and the current lucky number is available in one place.
- Grades: View your grades and averages for each subject. You can also see the grades added the day prior. Librusek supports both the traditional and points-based (percentages) grading systems.
- Exams: Know when your upcoming exams take place. You can view all your upcoming and previous exams along with their dates, all neatly sorted and highlighted for your convenience.
- Timetable: Stay up-to-date with your daily schedule. You can view your timetable for each week, including all substitutions and cancelled classes.
- Attendance: Keep track of your attendance. You can view your attendance for each subject and see the number of absences and lates.
- Profile: Check your profile information, including your name and synergia email. You can also check your behavior grades and notes given by your teachers - both positive and negative.
- Messages: Read messages from your teachers and school administration regarding important information and events.
Since Librusek is a fully custom application, it has some unique features that are not available in the original Librus Synergia.
- Multiple themes: Librusek supports multiple themes, including a dark mode and a light mode. You can choose the theme that suits you best.
- Grades simulator: With the grades simulator, you can calculate the grades you need to achieve a specific average. You can also see how your average will change if you get a specific grade.
- Responsive design: Thanks to the responsive design, Librusek looks great on various mobile devices like smartphones and tablets.
- Modern design: Librusek has a modern and clean design that is easy to use and looks great.
- Fast and reliable: Librusek is built with modern technologies. It's - in most cases - faster than the official Synergia.
- Optimized data fetching: Librusek uses optimized methods for fetching data from the Synergia API, which makes it faster and more reliable. It also uses caching to reduce the number of network requests.

The idea for Librusek was born because of Librusik created by dani3l0. Some of the code (especially for authorization) was inspired by this project.
