How to play

  1. Type the task you want students to start on right now.
  2. Tap 3, 5, or 7 minutes to pick how long they'll have.
  3. Tap Start to go full screen — the task and a shrinking ring fill the display.
  4. Pause or resume anytime from the full-screen view, or Exit to return to setup.

The first few minutes of class set the tone for everything after, and this tool is built for exactly that window. Type the do-now or bell-ringer task once, tap one of three ready-made presets — 3, 5, or 7 minutes — and go full screen instantly. The task text sits huge at the top of the display so it stays readable from the back row, while a shrinking ring underneath gives a quiet, at-a-glance sense of how much time is left without anyone needing to ask. When time runs out, the ring empties, the screen shifts to a calm green, and a short chime signals it's time to move on. No typing a custom minute count, no separate task poster — just one tap and the room settles.

Frequently asked questions

Can I set a time other than 3, 5, or 7 minutes?
The three presets cover the most common do-now lengths with a single tap, so there's no custom minute field to fill in — pick the closest preset and start immediately.
Does the timer keep the task text visible the whole time?
Yes, the task stays large at the top of the full-screen display for the entire countdown, so students never lose track of what they're supposed to be doing.
What happens when the countdown finishes?
The ring fully empties, the screen changes to a calm green, and a short finishing chime plays, giving a clear signal to wrap up without needing to watch the clock.
