Breathing exercises for iPhone and iPad
A tool, not a drill.
Nine techniques, chosen rather than collected. Each has its own rhythm and a plain explanation of what it's for — so when you need one, you're choosing, not searching.
Use it twice a day or twice a year. We left the streaks out on purpose. No history, no session log, nothing in Aemble that could keep score. The day you need it most is usually the day you'd have broken the streak anyway.
Buy it once, nothing to cancel later. €6.99 / $6.99 — no subscription, no account, no analytics, and no technique behind a second purchase.
Coming soon to the App Store

No. Aemble is €6.99 / $6.99, once — every technique included, no subscription, nothing to cancel.
No — and at launch there isn't one. Aemble is an iPhone and iPad app. A watch app is built and waiting, and it'll come as a free update to everyone who has already bought it, not as a separate purchase.
Yes, properly — not a blown-up phone app. Turn it sideways and the whole library sits on the left with the technique you picked open beside it: tapping a different one changes the panel rather than pushing a new screen, so there's no going back and forth. Held upright it's a centred column with the paper running to the edges. The iPhone app is portrait.
No, and none planned.
An iPhone or iPad on iOS 18 or later.
The physiological sigh. Two breaths in, one long breath out — a single round takes ten seconds, and the default session is a minute. It's the quickest way to find out whether any of this is for you.
Because they were chosen rather than collected. A longer list would look more generous and be worse to use: the moment you need one is the worst possible moment to be browsing. Nine covers it, grouped by what you need them for, so the deciding is already done. Zero decision fatigue, by design.
Yes. There's a Home Screen widget — set it to your quick start or to any technique you like — and a control you can put on the Lock Screen or in Control Centre that starts your quick start in one tap.
It waits. Leaving the app pauses the session rather than restarting it, so you come back to the breath you left, not to the beginning.
English. German is written and waiting on a review pass.
Aemble is here to help you breathe with a little more intention. It's made for general wellbeing. Breathing exercises suit many people, though not everyone, and Aemble promises no particular result.
It is not a medical device. It doesn't diagnose, treat or prevent any condition, it measures nothing about your body, and it doesn't replace care from a doctor or therapist.
Go gently. If you feel dizzy, lightheaded or short of breath, notice tingling or changes in your vision, or feel any pain in your chest, stop and let your breathing return to normal. You can pause or close any session whenever you like. There's nothing you have to finish.
Not for emergencies. If you're having trouble breathing, use your inhaler or medication and get help. Aemble is not for those moments.
Check with a doctor first if you're pregnant, take regular medication, or live with a heart or lung condition such as asthma or COPD, high or low blood pressure, diabetes, epilepsy, or a history of fainting. The same goes if you live with anxiety, panic or depression: for some people, intensive breathing practice can make symptoms worse.
Breath holds. Box breathing, 4-7-8 breathing and Triangle breathing ask you to hold your breath, which doesn't suit everyone. Calming breath, Extended exhale, Coherent breathing and Resonant breathing have none.
Choose a safe moment. Never practise while driving, cycling, swimming, or anywhere a moment of lost focus could put you or others at risk.
Children should use Aemble only with an adult present.
If you're in distress or think you may be having a medical emergency, contact a doctor or call emergency services.
Questions: hello@twelvebelow.app
Nothing — and not in the "we anonymise it" sense. No account, no server, no analytics, no crash reporting, no third-party code. Nothing about you or your sessions ever leaves the phone, which is also why it works on a plane. The App Store privacy label reads Data Not Collected, across the board.
Your appearance setting, your quick start choice, the four session switches (count, sound, haptics, distraction-free), and the last length you chose for each technique. That's the list. Deleting the app deletes all of it, and there's nothing on our side to delete, because nothing ever left your device.
It keeps working. No server to switch off, no account to expire — the version on your phone is yours for as long as the phone runs it.
Swift 6 and SwiftUI, no third-party packages. The rhythm runs off a single monotonic clock, so ten minutes in, the circle, the count and the haptics are still exactly together. Full VoiceOver support — the pace is announced as it changes, with the phase, the round and the time left readable at any moment — Dynamic Type up to the largest accessibility sizes, and a Reduce Motion mode that holds the circle still and lets the words, the ring and the haptics carry the pacing.
