önd

Guided breathing, grounded in evidence.

A focused practice for iPhone and Apple Watch. Distinct haptics guide each time you breathe in, hold, and breathe out, so you can put the screen down, close your eyes, and follow the rhythm.

Coming soon on the App Store

Built for practice

Choose a Moment or an Exercise.

Choose a Moment for what is happening right now. önd pairs that situation with one recommended Exercise and sets up its rhythm and length. Choose an Exercise when you already know the pattern you want. Every exercise and moment is available from the start, and you can make your own exercise when a different rhythm feels better.

Choose a Moment for right now: Pick what is happening and start the exercise önd recommends. You can see the exercise, length, and rhythm before you begin.
Choose an Exercise directly: Browse every exercise, adjust the session, or save a pattern of your own. Clear cues, haptics, and optional sound guide the timing.
See your practice over time: Progress shows your sessions, minutes, and days practised. History keeps every session, including the time from one you ended early.

Box Breathing gives you a steady rhythm to follow. Research is growing, but it has not shown that the square pattern works better than other forms of slow breathing.

On your wrist

The Watch app runs a full session on its own.

Open önd on Apple Watch and start an Exercise or one of the Moments available there without reaching for your phone. The Watch shows one clear breathing shape and uses a different haptic for each phase. Sessions continue when the display turns off, and standalone Watch practice is part of the free app.

Evidence with limits

What the research shows, and where it stops.

Slow breathing reliably changes cardiovascular measures such as heart rate variability (HRV) while you practise. Studies also report possible benefits for stress, mood, and anxiety, but the results vary and lasting effects remain uncertain. No single pace or technique has been shown to be ideal for everyone.

That is how önd presents the evidence: what was studied, what changed, and where the limits are. Breathe comfortably rather than exactly to the count. If a pattern makes you dizzy or tingly, ease back or return to normal breathing.

Cyclic sighing

Cyclic Sighing can support a calmer daily practice

Cyclic Sighing asks you to breathe in twice, then take one easy, longer breath out. In one month-long study, five minutes a day improved mood and resting breathing rate more than three comparison practices. The study was small and has not yet been repeated.

Heart and Health

See your heart rate during and after a session.

During a connected phone-and-Watch session, önd can show your live Watch heart rate on the phone. Afterwards, a simple curve shows how it moved. There is no target zone or readiness number, and a single session cannot tell you whether the practice worked.

Save your practice to Apple Health: With permission, completed sessions write Mindful Minutes. Your answers about how you feel before and after a session write to State of Mind. önd does not store those answers.
Trends you choose to see: önd+ can show weekly context from sleeping breathing rate, resting heart rate, and HRV, along with your heart rate around each session. Access is off until you enable it, and önd uses weekly averages rather than a health score.

Honest pricing

Practice is free. önd+ adds the connected layer.

The core practice is permanently free: every Exercise and Moment, custom exercises, guided sessions with haptics and sound, the standalone Watch app, Progress and History, schedules, streaks, guidance in The basics, and Apple Health writes.

önd+ monthly — $1.99: One auto-renewing month.
önd+ yearly — $14.99: The same önd+ features for one auto-renewing year.

Eligible new subscribers can try önd+ free for seven days on either plan. önd+ adds a coach that answers in text using your goals, notes, and recent practice. It also adds optional leaderboards for streaks, comfortable pauses, resting breathing, and minutes; Health trends over months; and connected phone-and-Watch sessions. In a connected session, your Watch taps the rhythm while your phone draws it. Prices shown are for the US App Store. Apple sets local pricing and manages cancellation.

Private by design

No sign-in required.

Use önd, including önd+, without signing in to the app. Apple handles subscription payments through the App Store; önd receives the signed transaction, not your Apple ID, name, or email. Sign in with Apple is optional. It links your practice so you can recover it on another device. önd has no ads or third-party trackers, and Apple asks your permission before any Health data is read or written.
