Breathwrk turned guided breathing into an app people actually open every day, with a growing library of patterns sorted by goal: calm down, fall asleep, focus, get energized. But the part that does the actual work is small: a visual pacer that expands and contracts while you follow along, timed to a real technique. That part does not need an account or a subscription. So we built Breath Flow, a free guided breathing tool that runs right here in your browser. Pick a pattern, pick a length, tap start. No install, no signup.
Start a breathing session
Tap “Start session” and follow the circle as it grows and shrinks. Box breathing for three minutes is a solid default, and the circle is already animating before you tap anything.
How to use it
The circle expands as you breathe in, holds while it stays put, and shrinks as you breathe out, with a text label and a countdown number in the middle so you never have to guess what to do next. Three patterns are built in. Box breathing runs 4-4-4-4: equal counts in, hold, out, hold, good for a steady reset in the middle of a stressful day. The 4-7-8 pattern stretches the exhale to 8 counts, which leans on the body’s natural slow-down response and works well before sleep. Calm exhale runs 4 in, 6 out, 2 hold, an easier rhythm to sustain over a longer session.
Pick a session length of 1, 3 or 5 minutes, then tap start. A live countdown shows how much time is left, and a soft tone marks each phase change if you turn sound on with the speaker icon (it starts muted). Finishing a session adds to your streak and your count of sessions completed that day. Your pattern choice, streak, and session history are saved on your device only. Nothing leaves your browser.
How it compares to Breathwrk
Breath Flow keeps the piece of Breathwrk that carries the whole experience: a visual pacer you can actually follow, timed to real, named breathing techniques, with a session timer and a streak to keep you coming back. Box breathing, 4-7-8, and an extended-exhale pattern cover most of what people reach for a breathing app to do in the first place.
What we left out is most of why Breathwrk is worth installing. The real app organizes dozens of patterns by goal, from energy and focus to anxiety and sleep, and recommends routines based on how you say you are feeling. It adds multi-day courses that build a habit over weeks, background music options, reminders, and progress tracking synced to an account. Premium unlocks the full pattern library and the courses; the free tier gives you a starter set.
Use Breath Flow when you want two minutes of paced breathing open in a tab, right now, with nothing to set up. Get Breathwrk when you want a structured practice with more techniques, routines matched to how you feel, and reminders that actually nudge you to come back.

Frequently asked questions
Is this the real Breathwrk app?
No. Breath Flow is an original tool we built, inspired by the guided breathing pacer inside Breathwrk. We are not affiliated with, endorsed by, or connected to Breathwrk in any way. For the full pattern library, personalized routines, and guided courses, get Breathwrk from the stores above.
Does it work offline?
Yes. Once the page loads, Breath Flow runs entirely in your browser with sounds synthesized on your device, so it keeps working without a connection. Your streak and session history are stored locally on your device and never uploaded anywhere.
Is Breath Flow free?
Yes, completely. There is no signup, no download, and no usage limit on the three built-in patterns or the session timer.
Can I do a guided breathing exercise in a browser?
Yes. Breath Flow needs nothing but a browser tab. It works the same way on a phone, tablet, or desktop, and there is nothing to install.
Does guided breathing actually help with stress?
Slow, paced breathing is one of the better-studied quick relaxation techniques, and patterns like box breathing and 4-7-8 are widely used to settle the nervous system before something stressful or before sleep. This is a relaxation tool, not medical advice. If you deal with ongoing anxiety or a breathing condition, talk to a doctor rather than relying on an app, ours included.
