The Chrome-specific flow, start to finish.
A short tour of the widget. Already sold? Skip ahead.
Chrome aggressively throttles JavaScript timers in background tabs to save power, so any web Pomodoro that runs as JavaScript-only can drift by minutes if the tab isn't focused. The Start Page HQ Pomodoro Timer sidesteps this by storing the start time and computing remaining time on read — when you flip back to the new tab, it shows the correct phase and remaining seconds even if Chrome paused the tab's clock for ten minutes.
The sound cue uses HTML audio that's gated behind Chrome's autoplay policy, which means it only fires reliably after you've interacted with the new-tab page at least once in the session. Pressing Start counts as that interaction, so subsequent phase-end chimes play as expected. If you keep the tab open for hours without focusing it, briefly clicking the dashboard re-arms the audio.

Pair the Pomodoro Timer widget with these. One install gets you all of them.
The Pomodoro Timer widget is one of 50+ in Start Page HQ. Tasks, notes, RSS, AI tools, dev utilities — the same install gives you all of them. $25/year or $49 lifetime, no free tier.
Yes. The widget records when you started and computes the remaining time when the tab is foregrounded again. Even if Chrome throttles the tab's background JavaScript, the displayed time stays accurate to within a second.
Chrome's autoplay policy blocks audio in tabs where the user hasn't interacted with the page yet. Pressing Start arms audio for the rest of the session. If you re-open Chrome and load the dashboard but never click anything before the first phase ends, the sound is suppressed — click the dashboard once to re-enable it.
Not currently — the Pomodoro widget signals phase changes inside the new-tab page (visual + optional sound) rather than via Chrome's notification system. That's deliberate: the dashboard is meant to be the place you look when you're between focus blocks, not something that pings you while you're heads-down in another window.
Yes. Sign in once and your durations, display style, and sound preferences follow you to every Chrome you install Start Page HQ on. Sync is part of the base plan, not a separate upgrade.
