Veewoo Timer

Veewoo Timer is a Next.js PWA (Progressive Web App) that works as a daily task timer with a Pomodoro-style 25-minute focus timer. You pick tasks, run the timer, and it tracks time per task.

Task and active-timer changes are saved to this browser first, so previously loaded tasks remain usable offline. Changes that cannot reach Google Sheets are queued locally and retried when the connection returns or when you use the Sync button. Pending local changes take precedence over the sheet until they sync. Local data is specific to the browser/device and is cleared if its site data is removed.
