Breathe at the pace you choose, eyes closed.

02 · How it works
Three numbers, one breath.
Pick your seconds
Inhale 4, exhale 6. Or hold at the top, or at the bottom, or both. Each step goes from 1 to 60 seconds, in half seconds.
Follow the tone
The tone climbs gently while you inhale and sinks while you exhale, on your exact durations. Eyes closed, you still know where you are.
Press start
The screen stays awake, the space bar pauses on a computer, and your rhythm is saved for next time.
03 · Pro
Everything else, unlocked.

Cardiac coherence, 4-7-8, box breathing, the physiological sigh, each with its usual length.

A calm voice says "breathe in", "hold", "breathe out" exactly when the phase starts.

Rain, waves, wind or a soft drone under the tone, with their own volume.
Timed sessions
From 1 to 20 minutes, always ending on a complete breath.

04 · Questions
Why do I need an account for the free guide?
So your rhythm is still there next time, on any device. Sign-in is Google only, no password, and only your email address is read.
I hear nothing on my iPhone.
On iPhone, the silent switch also mutes sound from web pages. Turn it off, raise the volume a little, and press Start again. The tone is soft on purpose.
Is this a medical tool?
No. Tidal is a wellbeing aid that paces your breathing. If you feel dizzy, stop and breathe normally. Ask a doctor about any breathing or heart condition.
What exactly does the payment unlock?
Everything listed above, for the life of your account: library, presets, guided voice, soundscapes, timed sessions and the journal. One payment, no renewal.
Can I delete my data?
Yes, from the account page, at any time. Your rhythm, presets and journal are erased immediately.
