Chalktick

Chalktick is the classroom timer built for teachers who project to a screen. One tap starts a full-screen countdown your whole class can read from across the room. Color tells the story: the ring starts teal, shifts amber when time is running low, and turns red in the final minute — students know where they stand without checking a number. Save your go-to durations in the Library — Silent Reading, Group Work, Quiz Time, Bathroom Break — and reuse them with a single tap all week long. No setup, no account, no network required. What you can do: • Start a countdown in one tap from preset durations (2, 5, 10, 15, 20, 30 min) or any custom length • Visual phase progression: teal → amber → red for instant at-a-glance status • Save named timer presets and organize your whole teaching day • Audible + haptic alert when time is up (Bell, Chime, Buzzer, or Silent) • Screen stays on during active timer — no mid-class auto-lock • 100% offline — works on day one, works on a plane, works forever Chalktick Pro unlocks: • Run up to 3 simultaneous timers for station rotations and parallel activities • Unlimited saved presets • Custom accent colors per preset No subscription. No account. No ads. Just a timer that works.
