LessonFlo is the interval timer designed specifically for teachers. Create flexible lesson plans, manage segments effortlessly, and keep your class on track.
Available for iPad • Coming soon to Android
                Large, clear countdown timer with progress rings that students can see from anywhere in the classroom.
Pre-built lesson segments with icons - Introduction, Group Activity, Assessment, Video, and more. One tap to add to your lesson.
Need more time for a discussion? Skip ahead when a video ends early? Our intelligent time redistribution gives you three options: distribute remaining time by segment priority, add it to a specific activity, or simply end class early.
Plan lessons in advance and view your teaching schedule at a glance with day, week, and month views.
Each lesson element has its own color for quick visual identification and better organization.
Add notes to each segment to remember key points. View your notes side-by-side with the timer during lessons.
Extend the current segment by 2, 5, or 10 minutes with one tap. Time is automatically borrowed from remaining segments using priority-based or even distribution. Never reduces any segment below 30 seconds.
Change your lesson plan mid-lesson! Drag and drop to reorder segments even while the timer is running.
Assign priority ratings (1-10) to each segment. When redistributing time, higher priority segments receive more time, ensuring your most important activities are protected.
Feel every interaction with subtle haptic feedback. Get notified with gentle vibrations when segments complete, so you can stay focused on teaching.
Choose from pre-built lesson elements with icons. Drag and drop to arrange your lesson timeline, set durations, and reorder segments easily.
                            
                        Visual timer with multi-segment progress rings shows exactly where you are. See upcoming segments and teaching notes at a glance.
