The SELM - Lápis Teaching System app is an optimized electronic daily school diary in the form of an app that allows students/guardians to instantly access all school-related information via their cell phones. It is a mobile app used by students/guardians to receive daily information of interest, generated by teachers/school coordinators, and also allows them to send information to the school.

It provides students/parents/guardians with access, via their smartphones, tablets, and computers, to daily school information, such as:

- Daily classroom routine;
- Homework assignment notices;
- Test subject information and test dates;
- Messages requiring immediate, urgent information;
- Notices sent by the teaching staff and the administration;
- Notices of various events (celebrations, meetings, etc.);
- Notifications by students/parents to the school of any missed class;
- Direct access to educational websites recommended by the school.

The SELM - Lápis Teaching System app includes the same fields as traditional paper diaries, in addition to offering new and exclusive areas for school monitoring. This allows you to record daily routine information and details about various school announcements and notices, as well as record events through images (photos). Furthermore, the app includes a message field where the school can write important information for students and/or their family members (guardians) and vice versa. It is worth noting that the app allows students or their guardians to receive it instantly when a teacher records information in any of the diary fields or records a message for the app.

Licenses must be purchased from the school and will be sent to students/parents as soon as payment for the login is confirmed.

Students/parents must download the app free of charge from specialized stores and then log in using the information provided by the school. Students/parents may choose to purchase one or more subscriptions.
