The Pomodoro Focus Timer & Site Blocker for Chrome

Customisable work cycles, domain blocking with a strict mode you can't casually switch off, and wellness breaks that arrive on time — in one free extension.

DeepCycle is a deep work browser extension for the place deep work actually goes to die: the open tab. It runs your Pomodoro cycle, blocks the sites that break it, prompts you to rest your eyes and move, tracks your water, and turns the whole thing into a streak and a desk plant you would rather not kill.

Focus, Then Recover

A Focus Timer That Also Looks After the Human

Most focus tools do one half of the job: they count down, or they block. DeepCycle pairs the timer with the blocker, then adds the recovery half — eye rest, movement, hydration — because the reason a cycle collapses is rarely the timer.

Who It's For

Who Uses DeepCycle?

If your best work needs an uninterrupted hour and your browser reliably refuses to give you one, this was built for you.

Remote Workers

Nobody is walking past your desk to see what is on your screen, which means the only structure your day has is the structure you install. DeepCycle supplies the cycle, blocks the tabs that dissolve it, and keeps a record of what you actually focused on — useful when the week blurs and you cannot remember where it went.

Students

Study in timed cycles instead of open-ended sessions, block the sites that turn a revision hour into a scroll, and watch the streak build across the term.

Writers

Draft with a soundscape running and research tabs blocked, so the sentence you are on stays the thing you are doing.

Developers

Deep work is the entire job, and the browser is also the tool. DeepCycle blocks the parts of the internet that are not documentation while leaving the rest alone, and the timer keeps a debugging session from quietly eating an afternoon without a single break.

Focus Strugglers

If sustained attention is the hard part rather than the willing part, external structure helps: a visible timer, a hard block, and a prompt when it is time to stop.

Freelancers & Solo Founders

Work in measurable blocks, see which days were genuinely deep, and use the heatmap as an honest record rather than a guess.

Anyone Whose Deep Work Doesn't Survive an Open Browser

The intention was never the problem. You sat down to work, one tab wandered, and forty minutes later you are somewhere you did not choose to be. DeepCycle makes that path cost something: the timer is running, the site is blocked, strict mode wants a password, and the plant on your desk is watching.

Core Features

Everything That Holds a Cycle Together

Eight systems that each remove one specific way a focus session falls apart — from the tab you did not mean to open to the four hours you spent without standing up.

01 / 08

Customisable Pomodoro Timer

Set your own work and break lengths instead of inheriting someone else's 25/5. Real-time visual overlays keep the remaining time visible without you switching to check it, and multi-sensory notifications mark each transition so a finished cycle never runs on unnoticed. The point is that the decision about when to stop is made once, at the start, rather than renegotiated every ten minutes.

Simple Workflow

How DeepCycle Works

Four steps from a browser full of exits to a cycle that finishes.

01

Set Your Cycle

Choose work and break lengths that match how you actually concentrate, and set your health-break and hydration intervals.

02

Block What Breaks It

List the domains that end your sessions, schedule when blocking applies, and switch on strict mode if you want it locked.

03

Work the Session

Start the timer, pick a soundscape, and work. Overlays show the time left; eye-rest, movement, and water prompts arrive on cue.

04

Review & Grow

Check the heatmap and wellness score, extend the streak, and watch the desk plant move through its four growth stages.

Full Feature Set

More Inside the Extension

The smaller controls that make the difference between a timer you use for a week and one that stays installed.

Custom Cycle Lengths

Work and break durations you set yourself, not a fixed 25/5 preset.

Real-Time Overlays

The remaining time stays visible on the page without switching tabs to check it.

Multi-Sensory Alerts

Transitions between work and break are announced, so cycles do not overrun unnoticed.

Strict Mode Password

A password stands between an impulse and an unblocked site mid-session.

Blocking Schedules

Apply the block list on the days and hours you choose instead of always-on.

Your Own Block List

Block by domain, so documentation and research stay reachable while time sinks do not.

Built-In Soundscapes

Lo-fi, rain, and cafe ambience included and ready without assembling a playlist.

Custom .mp3 Upload

Bring your own audio if the built-in library is not what you work to.

Hydration Goals

Set a daily water target and log intake through interactive reminders.

4 Plant Growth Stages

The desk plant advances through four stages as completed focus cycles accumulate.

Focus Streaks

Consecutive focus days are tracked, giving consistency something to protect.

Activity Heatmaps

See which days and hours were genuinely deep instead of relying on memory.

Wellness Score

A single summary of how your focus time and your breaks balanced out.

Alt+Shift+D Shortcut

Toggle DeepCycle globally from the keyboard without reaching for the toolbar.

Privacy First

Your Focus Data Stays On Your Device

A focus tracker sees a lot: which sites you had to block, when you concentrate, when you stopped, how often you took a break. DeepCycle's developer declares on the Chrome Web Store that no user data is collected — and that none is sold or shared with third parties. There is no account to create, so there is nothing to sign in to and nothing sitting on a server under your name.

What stays with you:

Your block list the domains you chose to block, and when the schedule applies
Your focus history cycles, streaks, heatmaps, and the wellness score behind them
Your wellness settings break intervals, hydration goals, soundscapes, and uploaded audio

Declared on the Chrome Web Store listing: this developer declares that your data is not being sold to third parties, not being used or transferred for purposes unrelated to the item's core functionality, and not being used or transferred to determine creditworthiness or for lending purposes.

Why We Built It

Because the Timer Alone
Was Never Enough

The Pomodoro Technique is old, simple, and genuinely effective: work in a focused interval, take a short break, repeat. It also assumes something that stopped being true a long time ago — that when the interval starts, the only thing in front of you is the work. Nobody's browser has worked that way in years.

So a timer on its own tends to lose. It counts down honestly while the second tab does whatever it likes, and the session is gone before the bell. The blockers solve that half, but they solve it in isolation: a hard block with no rhythm becomes something you switch off, and neither tool has anything to say about the fact that you have not stood up or looked away from the screen since morning.

DeepCycle puts all of it in the same place. The cycle defines the shape of the session, the blocker defends it, strict mode keeps the defence honest, and the wellness prompts — eye rest, movement, water — handle the recovery half that decides whether the next session is any good. The plant, the streak, and the heatmap exist because habits that leave a visible trace are simply easier to keep.

Cycles You Define

Work and break lengths that fit your attention, not a default.

Blocking With Teeth

Strict mode stops the block from being lifted on impulse.

Recovery Built In

Eye-rest, movement, and water prompts arrive without being remembered.

Sound That Starts Itself

Soundscapes run with the cycle instead of costing you a playlist detour.

An Honest Record

Heatmaps and streaks show which days were actually deep.

Free, No Account

Every feature included, nothing collected, nothing to sign up for.
