A little structure for the things that matter.
Choose your atmosphere. Open the gear beside Help to choose Calm, the default light theme, or Midnight, a dark theme. Use Enter or Space to open settings, then arrow keys to select a theme. Escape closes settings and returns to the gear; clicking or tabbing outside also closes settings. Your theme saves in this browser and follows across open tabs.
Make it a routine. Select any weekdays on the left to repeat, then choose how many weeks between repeats on the right of the same row. Type the interval, use the arrows above and below the number, or press Up and Down in the weeks field. These controls sit below the 60-minute bar on timer cards, above the to-do list. With no days selected, a new timer runs once. The start date anchors the Monday–Sunday week. Each recurring countdown starts 16 hours before its scheduled local deadline, sometimes on the previous calendar day.
Every timer card has weekday and week-interval controls. Edits to existing timers and alarms save immediately. Clear all days on a timer card or in the “Recurring” editor to remove the schedule and keep existing countdowns as one-time timers. Adding recurrence to a one-time card uses its finish date, time, and to-dos for future timers. Invalid values show an error and keep the last valid saved value.
Reopening within the 16-hour window before an alarm recovers its countdown; missed occurrences are skipped. Renaming, adjusting, or deleting a timer affects only that occurrence. Manage future occurrences in the “Recurring” view; its editor stays in that view. During daylight-saving changes, skipped times move forward and repeated times ring once.
Only one countdown per alarm can be active. If an extended or paused timer overlaps the next activation, the next countdown waits; it is skipped if its deadline passes. Schedule edits leave the current countdown unchanged. When tabs save conflicting schedule edits, the last save wins; deadline adjustments apply to the latest saved countdown.
Start with the finish. Edit the new timer card in the grid: add an optional name, choose a finish time and date, then start it. Use “New timer” to add another card at the front of the grid.
Use “Timers” for all your countdowns, including finished timers, and “Recurring” to create or manage schedules. Switch views with the arrow keys when a view tab is focused, or use Home and End. Switching views keeps your open draft. New items use Start timer or Create alarm; Cancel discards a new draft. Existing edits save automatically, including when you close the editor.
Make space for smaller steps. Choose “Add to-do list” to create a row, then “Add to-do item” for more. Each row has a checkbox, a single-line task, and optional minutes (0–999 whole minutes). Blank minutes are saved as 0. Saved rows display as plain text when focus leaves. Click or Tab to a task or its minutes to edit; moving between controls in the row keeps it editable. Tab from the last Minutes field adds a row and focuses its text field. Press Escape to reach the add button and Tab to leave the list. Use a row’s trash button to delete it immediately. Hovering or focusing the trash button highlights that row in red. Leaving a row deletes it automatically only when its text is blank and its minutes are blank or 0. Text-only items and items with positive minutes are kept. A warning appears when unchecked items need more time than remains. Recurring alarms can save a template; each new timer gets an unchecked copy.
Pause when you need to. Pausing holds the time remaining; resuming moves the finish time forward.
Keep your next finish in sight. Timers are ordered by their finish time. To-do minutes do not change the order. Only the next timer shows seconds. Each bar represents a minute, showing the next 60 minutes to expire when more than an hour remains. The final 3 minutes are red and the preceding 7 are yellow. Unchecked to-do minutes extend these ranges: every 10 adds 3 red and 7 yellow minutes. Leftover minutes follow yellow, yellow, red, yellow, yellow, red, yellow, yellow, red, yellow, applied once to the total across unchecked items. Completed items and 0-minute items add nothing. Red stays nearest the deadline, followed by yellow, then green; warning colors can remain off-screen to the left until they approach. Editing, adding, deleting, or checking an item updates the colors without changing the countdown. In the final hour, bars deplete and the leading bar pulses with each second. Finished timers stay at the front and are automatically deleted 30 minutes after their deadline. This also happens when you reopen the app. Recurring schedules stay saved.
Timers save automatically in this browser. Keep this page open to hear alerts with sound on. Sleeping devices or background tabs may delay alerts; countdowns catch up when you return. If storage fails, changes stay in this page session. Unreadable saved data is preserved; keep the page open and copy any new timer details before reloading. Clearing browser data removes saved timers.
