New: a Sleep tab. A few slow breaths, then rain or waves play on with the screen locked and fade out on their own. And mindful minutes in Apple Health. Tide is a breathing timer that opens ready to go, and lets you set anything you like. Seven patterns are built in: Resonance — even in, even out, no holding. The calm baseline. 4-7-8 — in for four, hold for seven, out for eight. A strong downshift. Box — equal on all four sides. Steady and level. Extended exhale — out for longer than in. Physiological sigh — in, then a short second breath in on top, then a long, slow breath out. Power breathing — thirty deep breaths, then holding on a full one, over several rounds. Sit — nothing paced and nothing counted, for when you want no instruction. YOUR OWN PATTERN Set the inhale, the hold, the exhale and the second hold to any whole number of seconds you want, and it becomes a protocol like any other — same figure, same tone, same timer. Several of the best-known apps put their breathing patterns behind a subscription. These are decades-old public techniques with numbers for names. Nothing here is behind anything. Resonance, Box and Extended exhale run at the pace you choose, from four to seven seconds in half-second steps, so 5.5 is there if that is your number. BREATH HOLDS, HANDLED PROPERLY Most breathing apps stop at box and 4-7-8. Tide includes power breathing with long breath holds, and puts a safety note in front of it that you have to read: never in or near water, never while driving, sit or lie down first, stop whenever you want. It says plainly that the breathing will probably make you light-headed and tingly, and that some people faint. If you are pregnant, or have a heart condition, epilepsy or high blood pressure, it tells you to speak to a doctor. WHAT EACH ONE DOES The Protocols tab explains the mechanism behind every pattern — why a long exhale does the work in 4-7-8, why around six breaths a minute is where heart rate and breath fall into step, why the short second breath of the sigh fills the lungs to the top. It describes what happens physiologically. It does not promise you an outcome, because nobody can. THE FIGURE You follow a figure of nine strata of light that rises as you breathe in and settles as you breathe out — not another expanding circle. You can run a session with your eyes shut and follow the sound alone. SOUND, AND A ROOM FOR SLEEP An optional guide tone marks each phase, and three field recordings can play underneath: rain, waves, and an open hearth. A struck singing bowl marks the couple of moments in a session that earn one. All are public-domain recordings, bundled with the app, with their provenance recorded in the app itself. The Sleep tab has Wind down: a few slow breaths, then the sound keeps playing while the screen dims and you fall asleep, and fades out on its own after 15, 30 or 60 minutes. The sound carries on with the screen locked, so the phone can go face down on the nightstand. QUICK START Tide has a Breathe shortcut for Siri, Spotlight, the Shortcuts app and the Action button (iOS 16 and later). It opens Tide ready on the pattern you pick; Begin is still one tap. APPLE HEALTH, IF YOU WANT IT Switch on Apple Health in Settings and each finished session is saved to Apple Health as mindful minutes. Tide only writes there: it asks for no read access and cannot see anything in Apple Health, including the minutes it saved. It is off until you switch it on. QUIET BY DESIGN There is no streak to break, no notification telling you that you missed a session, and no library to work through. A session ends and closes rather than selling you the next one. Everything runs on the device, with no account and no connection required.

A new icon: the sun and the tide. A calmer finish screen: the figure stays, one Close button. Just the sound is easier to find in Sleep. Practice no longer calls last night's session Today.
