Lesson Timer is a FREE Windows tool for teachers to help manage the timing of lessons and other activities.
Tell Lesson Timer the timing of your lessons.
Lesson Timer will count down towards the end of each lesson automatically.
Lesson Timer has a wide variety of settings to adjust the appearance and behaviour of the timer.
School bells are particularly bad at being the correct time. You can adjust Lesson Timer so it matches the time according to your school system. Either make a manual adjustment or do it automatically.
