Die OSG App bringt das Schulportal des Otto-Schott-Gymnasiums Mainz auf Smartphone und Tablet. Stundenplan, Vertretungen, Termine und Mitteilungen der Schule sind immer auf dem aktuellen Stand. Schülerinnen und Schüler sehen ihren Stundenplan, die Vertretungen, die Schul- und Kursarbeitstermine, ihre Fehlzeiten und die Liste der Lehrkräfte. Sie chatten mit Klasse und Lehrkräften, finden Material und geben Aufgaben in der Lernumgebung ab, lesen die Mitteilungen der Schule, planen ihre Wochenaufgaben im Lernbegleiter und nehmen an Videokonferenzen teil. Eltern erhalten Elternbriefe digital und bestätigen sie direkt in der App, sehen Stundenplan und Vertretungen ihres Kindes, behalten die Fehlzeiten im Blick, kennen alle Termine der Schule und chatten mit Lehrkräften. Lehrkräfte führen Klassen- und Kursbuch, erfassen Fehlzeiten, tragen Noten ins Notenbuch ein, chatten mit Klassen, Kursen und Kollegium und verschicken Mitteilungen und Elternbriefe. Bei Vertretungen, Stundenplanänderungen, neuen Chatnachrichten, Elternbriefen und neuem Material in der Lernumgebung kommt eine Push-Benachrichtigung. Jede Art lässt sich in den Einstellungen einzeln abschalten. Mehrere Konten, etwa für Geschwisterkinder, lassen sich in einer App nutzen. Dateien und Fotos können direkt aus anderen Apps ins Portal geteilt werden, und es gibt ein helles und ein dunkles Design. Die Anmeldung erfolgt mit den Zugangsdaten des Schulportals. Die App ist nur für Schülerinnen und Schüler, Eltern und Lehrkräfte des Otto-Schott-Gymnasiums Mainz nutzbar.
