Sometimes you just need a timer that’s one click away — no app switch, no phone, no searching through tabs. Chrome extensions for timers and Pomodoro focus sessions live in your toolbar and are ready whenever you need them. Here are the three that are actually worth installing.
Short Answer: The Marinara Pomodoro Assistant and Be Focused extensions are the best Chrome timer tools — one for structured Pomodoro sessions, one for simple countdown timers that stay in your toolbar.
What Makes a Good Chrome Timer Extension?
A good timer extension should be: visible without opening a new tab, customizable without overwhelming you with settings, and non-intrusive between sessions. The ones below all hit that balance differently depending on whether you want a strict Pomodoro structure or just a quick stopwatch.
1. Marinara: Pomodoro Assistant
Marinara is the most popular Pomodoro timer in the Chrome Web Store — and for good reason. It sits in your toolbar showing the current timer countdown, supports custom work/break intervals, tracks your sessions over time, and sends desktop notifications when intervals end. The free version covers everything most users need.
Best for: people who want the full Pomodoro Technique with session history and tracking.

2. Be Focused — Focus Timer
Be Focused is cleaner and simpler than Marinara. It shows a countdown timer in the extension icon itself so you can see the time remaining at a glance without opening the popup. Supports Pomodoro intervals but doesn’t push the methodology — you can set any work/break structure you want. Free tier with optional paid upgrade.
Best for: people who want a lightweight visible timer without the full Pomodoro tracking overhead.
3. Simple Timer
Exactly what it says — a simple countdown timer extension. You set a duration, it counts down, and it plays a sound when done. No accounts, no session tracking, no methodology. If you just need a kitchen timer in your browser for one-off tasks (waiting for a download, timing a break, reminding yourself about a meeting), this does it with zero setup.
Pro Tip:
Chrome’s built-in omnibox can also set timers — just type ‘timer 25 minutes’ in the address bar. It’s instant but lacks the persistent toolbar counter. For ongoing focus sessions, an extension is more visible.
Quick checklist:
- ✅ Marinara — install if you follow Pomodoro Technique regularly
- ✅ Be Focused — best for lightweight visible countdown in the toolbar
- ✅ Simple Timer — for one-off countdown needs without any methodology
- ✅ Chrome omnibox timer (type ‘timer X minutes’) — quickest option if extensions feel like overkill
Frequently Asked Questions
Do these extensions work offline?
Yes — all three run locally in your browser. No internet connection needed after installation.
Will these drain browser performance?
Timer extensions are extremely lightweight — they use negligible CPU and memory. They’re one of the least resource-intensive categories of Chrome extension.
Can I mute the timer notifications?
All three support configurable sound notifications. You can turn off sounds in their settings while keeping desktop (visual) notifications active.
What’s the Pomodoro Technique?
A time management method: work for 25 minutes (one “Pomodoro”), take a 5-minute break, repeat. After four Pomodoros, take a longer 15-30 minute break. Designed to maintain focus while preventing mental fatigue.

The right choice depends on your workflow. If you’re a committed Pomodoro practitioner, Marinara has the best tracking. If you just want a timer visible in your toolbar at all times with minimal friction, Be Focused wins. And if you occasionally need a countdown for one thing, Simple Timer (or the Chrome address bar) is all you need.
