Guides
These how-tos are written against the live onetimer UI — Pomodoro, Timer, date countdown, and embed URLs — not generic timer theory. Each article walks through the toolbar, Settings, fullscreen, and the failure modes that actually stop a session: a closed or sleeping tab, laptop sleep, and browsers blocking sound until you tap Start.
Use the study timer or 20-20-20 guide when you need repeating Focus and break cycles on /pomodoro. Use the Notion guide when you want a live /embed/timer block inside a workspace page. Use the PowerPoint guide when you need named duration timers on /timer sitting beside your slides.
The four articles below are the full how-to corpus. Open the linked module and follow the steps; do not expect a background tab or a sleeping laptop to keep ringing.
