Ratings & Reviews

  • This app hasn’t received enough ratings or reviews to display an overview.

A guided first-run experience makes LessonOS easier to start with. New users see a six-slide visual tour that previews how students, classes, attendance, leaves, and per-student analytics actually look — not just descriptions, but real UI previews. After the tour, empty screens now provide a clear "Add Your First Student" call-to-action instead of a blank list. Step-by-step hints guide you through the first full cycle: add a student, schedule a class, take attendance. Available in 7 languages: English, Simplified Chinese, Japanese, Spanish, Malay, Indonesian, French.
