Why switch

Browser timers die with crashed tabs and lost wifi. Ads interrupt talks. A desktop countdown keeps countdowns local. Home: timer home. Cluster migration page: switch from online timers.

Steps

Install from winget or Releases: install on Windows. Recreate presets: countdown presets. Prove overlay: tray and overlay. First hour: installed.

What will not transfer

Streaks, themes, and social buttons stay in the browser. That is fine. You wanted the countdown job. Safety: is it safe. Download safe: download safe.

Keep both when needed

Locked lab accounts may still need browser timers. Personal desks can standardize on Catime. Comparison: vs Windows Clock timer. Updates: update and uninstall.

Desk operations without noise

Write the update door on a card beside the monitor so the next person does not invent a mirror. Prefer winget id VladElaina.Catime or catime_*.exe from GitHub Releases, then prove one short countdown after every reimage before a live talk.

Shared rooms should announce which countdown tool owns the projector machine. Students improve faster when the overlay stays readable and advertising tabs stay closed.

  • Parents should prefer verified package ids because they are harder to spoof than a random download button.
  • When wifi drops mid-session, a local Windows countdown keeps going offline after the first install.
  • Keep phone apps for travel if you want them, but let the desk stay local with one honest update door.

Lab and travel cards

Classroom images should pin the exact install door beside the OS version. After every reimage, prove one short countdown before you call the machine ready.

That habit catches vanished portable folders and adware shortcuts that reappear from old bookmark exports.

Travel laptops benefit from a single documented installer door written beside the folder that holds the portable. Lab images drift when someone installs a second mirror during a blocked SmartScreen prompt.

Return to the home install panel when you need pillar links again. Releases stay on timer releases. Safe fetch habits stay on download safe. Troubleshooting stays on troubleshooting when the tray icon hides or SmartScreen blocks a portable you already verified.

Frequently asked questions

Is there an import file?

No special import file moves browser timer bookmarks into Catime on Windows. Write down your common durations, recreate them as local presets after install, and keep the browser tab only as a temporary fallback during the first proof week.

Should I delete bookmarks immediately?

Keep the bookmark for one proof week as a fallback, then archive it after seven clean desktop sessions. Deleting too early tempts a panicked search that lands on adware mirrors.

What about phone timers?

Keep phone timers for travel days and hallway transitions. Use the Windows desktop timer for desk overlays and offline PC sessions where a phone buzz would be the wrong cue during a talk or coding block.
