Segflow turns any lesson into a precisely-timed sequence of segments — so you stay on pace, and your students always know what's coming next. Built for teachers, tutors, coaches, and workshop facilitators who need a fast, reliable timer they can trust without a learning curve. — Create a lesson plan in seconds: name it, add segments (Warm-Up / Lecture / Practice / Wrap-Up), set durations, hit Run. — Auto-advance: when a segment ends, Segflow moves to the next one with a haptic pulse — no tapping required mid-class. — Built-in templates for 50-min classes, 90-min workshops, and 30-min tutoring sessions to get you started immediately. — Session history keeps a record of every class you've run. — Pro: fullscreen projector mode displays the timer and segment name at classroom-screen size — project it, share your screen, or hand it to a student timekeeper. Fully offline. No account. No tracking. Just a clean, focused timer that gets out of your way.

Founder quote

“Segflow: Lesson Timeris built around one principle: your data stays on your device. We don't want it, we don't store it, and we don't need it to make the app work. Everything that can run locally, does.”
— Peter Zhang, solo developer, Obelisk Club
