A lock-screen countdown that shows teachers how long is left in the period
Asked for by a student teacher on r/SomebodyMakeThis · original source · more from r/SomebodyMakeThis
A student teacher wants to see at a glance how much of each class period remains, without a loud alarm. Enter a bell schedule once, then show a quiet always-visible countdown on the phone or a classroom web page. A full-screen web version works first; a native Live Activity can come later.

The weekend plan
A rough weekend-sized plan to help you start. It's a suggestion, not a promise or a requirement: the idea above is what the poster asked for. Change anything. About the steward
- Done for one weekend
- A teacher enters their bell schedule once, and a full-screen web page quietly shows the current period and how many minutes are left.
- Suggested shape
- Full-screen web page for a phone or a classroom screen
- In scope
- Enter the bell schedule once (period names with start and end times) and keep it saved in the browser.
- A big, calm countdown for the current period, plus what's next. Between periods, it says so.
- No sounds or alarms.
- Large text that reads at a glance on a phone, or from across the room on a classroom screen.
- Optional, if there's time
- Different schedules for different days, such as a short day.
- A native lock-screen version (an iPhone Live Activity), which the poster suggested for later.
