Copy this iframe
<iframe src="https://gotimer.org/e/countdown?duration=1500&label=Deep+work&theme=light&accent=%23E8613C"
  width="100%" height="420" frameborder="0"
  allow="autoplay" loading="lazy"
  style="border-radius:12px;border:0;max-width:480px;"></iframe>

Copy just the URL (the src="…" value) and paste it into a Notion Embed block.

How to embed in Notion (30 seconds)

  1. On the Notion page where you want the timer, type /embed and press Enter. Notion inserts a blank Embed block with a paste-URL prompt.
  2. Paste the GoTimer URL — for the deep-work timer above, paste https://gotimer.org/e/countdown?duration=1500&label=Deep+work (or any embed URL from /embed).
  3. Click Embed Link. The timer renders inline.
  4. Drag the bottom-right corner to resize. Notion remembers the size for that block.

Best Notion use cases

Daily Pomodoro on your home page

Add a 25-minute Pomodoro to the top of your Notion home page so it starts the moment you sit down. URL:

https://gotimer.org/e/interval?work=1500&rest=300&rounds=4&label=Pomodoro&theme=light&autostart=1

Sprint countdown on a project hub

Two-week sprint? Bake the seconds-remaining into the URL:

https://gotimer.org/e/countdown?duration=1209600&label=Sprint+end&theme=auto&accent=%23ff3b3b

Meeting time-box in a meeting notes template

Add a 30-minute countdown at the top of every meeting note. The timer resets when each new instance of the template is opened, since duration is computed from page load.

https://gotimer.org/e/countdown?duration=1800&label=Meeting&theme=light&accent=%230066cc

Deadline countdown in a wiki

Year-end planning page, OKR deadline, conference submission. Compute seconds-until-deadline once and embed:

https://gotimer.org/e/countdown?duration=2592000&label=Q4+deadline&theme=dark&accent=%23ff3b3b

Sizing tips for Notion

  • Sidebar widget — drag the embed to ~50% width and ~280px height. The default GoTimer renders cleanly at that size.
  • Hero header — full-width, ~400px tall. Pair with a covered image above and a heading below.
  • Inline in body text— use Notion's split-view layout (drag the embed next to a text block) for a writing page with a focus timer beside the prose.
  • Database card cover— Notion doesn't allow embeds inside database cards directly, but you can link a page inside a database to a full Notion sub-page that contains the embed.

Pomodoro vs. countdown — which to pick for Notion

  • Pomodoro / Interval: cycles between work and rest automatically. Best for daily focus pages. URL pattern: /e/interval?work=1500&rest=300&rounds=4.
  • Countdown: counts down once to zero. Best for sprint deadlines, OKR end dates, meeting time-boxes. URL pattern: /e/countdown?duration=….
  • Stopwatch: counts up. Best for tracking how long something took (a meeting, a writing session, a debug investigation). URL pattern: /e/stopwatch.

Limitations to know about

  • Notion mobile app — the embed renders inside the in-app browser. Some older versions of the Notion app block iframes entirely on mobile. The web version (Notion in Chrome / Safari on mobile) always works.
  • Synced blocks — embeds inside a Notion synced block render in all locations the synced block appears, but each instance is independent (no shared state). Useful if you want the same timer config in five workspace areas.
  • Published Notion pages — the embed shows up for public visitors of the published page; same iframe, same countdown. Notion sometimes lazy-loads embeds aggressively on published pages, so the first paint may show a loading skeleton for a fraction of a second.

For more advanced embed options (themes, accent colors, fonts, messages), use the embed configurator with the live preview — everything you can configure there is embeddable in Notion the same way.

Notion Countdown Timer Embed FAQ

Why isn&apos;t there a built-in Notion countdown widget?
Notion intentionally keeps its block library narrow. For dynamic content (timers, weather, polls) it ships an Embed block that accepts any iframe URL — that's the official mechanism for adding non-native widgets. GoTimer's embed is designed to feel native inside that block.
Will the timer keep counting if I close my Notion tab and reopen later?
Yes — the countdown is anchored by the iframe URL's duration parameter, and each page load recomputes time remaining from that anchor. Close and reopen the page: the countdown picks up exactly where the clock says it should be.
Can I add multiple timers to the same Notion page?
Yes — each Embed block is independent. Add a Pomodoro timer at the top of your daily note, a project countdown in your project hub, a sprint timer on your retro page. Each iframe runs on its own.
Will it work in a Notion Team or Enterprise workspace with strict embed policies?
Notion's embed allowlist permits any HTTPS URL by default. Enterprise admins can restrict embeds to a specific domain list — if your workspace blocks gotimer.org, ask your admin to allow it. The embed is purely visual; no data leaves the iframe.
Does the embed work on shared / published Notion pages?
Yes — when you publish a Notion page to the web (Share → Publish), the iframe renders for all public visitors. The countdown stays accurate because each visitor's browser computes the remaining time locally.
Can I embed a Pomodoro timer instead of a countdown?
Yes — use https://gotimer.org/e/interval?work=1500&rest=300&rounds=4 for a classic 25/5 Pomodoro. The embed page on /embed has a configurator for all timer types — pick "Pomodoro / Interval" and customise the cycle.
