For kids

Balloons and dragons
instead of timers.

Kids mode swaps the counter for a balloon that inflates and a dragon that breathes out sparks. PIN-gated so they can't wander into settings.

Why daily

Practice it on a calm day.
Use it on a hard one.

A few minutes a day anchors the state of calm in your body. So when the hard moment comes — a difficult conversation, a sleepless 3 a.m., a spike of panic — your nervous system already knows the way home.

Anchor the state

Repetition builds a neural groove. Calm stops being a mood you catch and becomes a place you can return to.

Regulate in real time

Slow nasal exhales pull the parasympathetic brake. Heart rate drops. Thinking returns. It works in sixty seconds.

Five minutes, not fifty

The floor is one session a day. Miss one, start again tomorrow. No shame streaks, no broken chains.

Train together

Get trained together
with the kids and family.

One account, up to six practitioners, a shared streak. Do a five-minute session before school, before a trip, before bed. Kids learn what adults rarely do: how to meet a hard feeling with a breath.

What people say

Early practitioners.

Short clips from the people testing BreatheFlow. Drop video embeds into the tiles below.

“I used to wake up at 3 a.m. with my chest racing. Five minutes of 4-7-8 before bed changed that in a week.”

Opel · Teacher

“My nine-year-old asks for ‘dragon breathing’ now. She does it herself before tests.”

Parent practitioner

“Box breathing every day for three months. Now when I come home wound up, my body finds the rhythm before I do — calm in under a minute.”

Common questions

The honest answers.

Is it free?

Yes — free for early users. Some features may become paid later. We'll tell you before anything changes.

Do you track me?

No analytics, no ads, no third-party scripts. Your data stays with you.

Does it work offline?

Yes — it's a PWA. Install it once, use it on the subway.

Can I use it on my phone today?

Yes. Open the web app in your phone browser and add it to the home screen — it installs like an app and runs offline. Android users who prefer a direct install can sideload the APK. Native iOS is on the roadmap.

Android

Prefer a direct install?

The web app already installs to your home screen and runs offline. If you'd rather sideload a signed APK — for deeper haptics or testing before the Play Store listing — you can. Android 8+ only. iPhone users, stick with the web app.

Download APK v1.27 · debug
~4 MB · Capacitor wrapper around the PWA
  1. Tap the download button on your Android phone. Chrome may warn "this file could harm your device" — that's the standard sideload warning. Tap Download anyway.
  2. Allow install from your browser. Open the downloaded file. Android will ask you to enable Install unknown apps for Chrome (or whichever browser you used). Toggle it on once — you can turn it off afterwards.
  3. Tap Install, then Open. BreatheFlow lands in your app drawer with a proper icon. Screen stays on during sessions, vibration/haptics work, and it runs offline once you've opened it once online.
This is a debug build. Unsigned by Google Play, logs enabled, slightly slower than a release build. Fine for trying it out — the Play Store listing will replace it when we ship.
