Reloj EDUmind brings together timers for the classroom, group work and independent study

Luis has created an installable web app with three timer modes, designed for managing time in class from nursery to vocational training.

Reloj EDUmind is an installable web app (PWA) that brings together the timers a teacher usually needs in class. According to its entry, it works offline, with no accounts and no tracking: data is stored on the device itself and can be exported or imported as a .json file. It was created by Luis as part of the EDUmind initiative, whose other resources the diary has already covered, such as the dictations with synthetic voices in Galician and Spanish.

The app is organised into three modes. Classroom mode offers a countdown that can be displayed as a disc that empties, as numbers or as a traffic light, as well as a stopwatch with laps and intervals of the Tabata, circuit or stations type, or custom ones. Groups mode lets you display from 2 to 8 timers at once; each group has a shape, a letter and a colour, so as not to depend on colour alone, and can run in free mode or by stations with automatic rotation. Self-management mode offers plans in phases, such as a pomodoro according to the stage, homework or studying a topic, or custom plans, with a wait between phases, a closing question, “How did it go?”, and a local log.

The latter serves, according to its author, to help students learn to organise their own study and not just to let teachers control the time. The project's documentation states that there are different styles depending on the stage: a friendlier one for nursery and primary, with a typeface designed for legibility and words instead of numbers for nursery, and a more sober one for secondary, sixth form and vocational training. According to that documentation, all the styles include dark mode, high contrast and reduced motion, and the interface is in Galician, Spanish and English.

According to its documentation, it is used by opening the website in the browser, with no registration, and it can be installed to work without a network. The code is open source, under an AGPL v3 licence according to the entry (the repository also declares the EUPL-1.2 option), and is available on GitHub for anyone who wants to adapt it. For a teacher, it can be useful for displaying a countdown during a test, rotating groups through stations in cooperative work or giving students a guided study plan with breaks.
