Was disappointed! ### 3/5 — No offline capability *2026-03-14, version 1.1.8* This app has some good aspects, like timed walking/breathing exercises. However if it's not connected to wifi, it stops working, which isn't ideal for walking outside, or users who live rurally. ### 3/5 — Needs work *2026-03-09, version 1.1.8* Potentially this is a great app and at first it appears very well put together. Unfortunately after only a couple of days of trying to follow a breathing plan, I’m finding the explanations of some of the exercises self contradictory and confusing. E.g. one exercise involves breathing into your cupped hands, just a nose full of air( ie a tiny volume ) but at the same time the instructions tell you that you should feel the exhaled air filling your hands. Well, my nose is not so big that a nose full will fill my cupped hands. Also, if I only breathe a nose full at a time, it’s almost like holding my breath completely, so I’m oxygen starved within a few seconds. As the exercise is only supposed to produce tolerable air hunger for someone with my Bolt score, I assume either the description of the exercise is wrong or the app is a bit glitchy. I’m experiencing this problem with one exercise in every daily breathing plan so far. I’m thinking of abandoning the app and just sticking with the basics that the breathing coach gave me in our face to face fee paying session. ### 3/5 — Full of unfulfilled promise *2026-01-23, version 1.1.7* This could be so much more. Unfortunately the slide bars on the daily readiness score are clunky compared to before, it’s not updated very often. I frequently get something went wrong when completing exercises. It’s lacking integration with Apple health and Apple Watch. It’s need a strong network connection not always possible when out walking. The instruction videos are a full length training tutorial so not suitable as a quick reminder and the main biggest gripe is the synchronicity of the audio files for the exercises meaning some instructions are late or missed altogether so you can’t sit calmly and follow instruction with eyes closed you need to watch the screen. ### 4/5 — Great app but music doesn’t work *2025-09-12, version 1.1.6* Hey guys, I love your app but after a few month of using the music has just stopped working. I’ve deleted and reinstalled and played with every single setting. I can’t get it to work! ### 4/5 — Absolutely love it but…. *2025-07-29, version 1.1.6* Sometimes it logs you out and says your password isn’t correct. Also, sometimes the app won’t even open and the screen just stays black. If that can get fixed I’ll revisit and edit this review because the app has soooo much packed into it to practice daily. ### 4/5 — This app is very useful BUT… *2025-06-07, version 1.1.6* Most of the time I want to use this app it won’t open. It glitches too much. ### 3/5 — App keep crashing *2025-05-21, version 1.1.6* I tried to use app in last week or so. However it’s keep crashing or being unresponsive. I reinstalled it few times and restarted the phone, but this didn’t solve the issue. Overall I like the app , but what’s use if you can’t use it .☹️ ### 4/5 — Please add watch support *2025-02-20, version 1.1.4* I am so grateful to have found OA. I love the app so far. The only thing that would improve the experience for me is if I could do my daily exercises without my phone, just using the Apple Watch. ### 3/5 — Crash/black screen *2025-01-26, version 1.1.4* What is up with the black screen and why does it happen? I use it for a couple of days, then I open the app to a black screen! When it is working the app is good. But I would like to use it when I need it and have the time. This is why I is use other apps and watch videos. I thought this time would be different. I have seen measurable benefits to using the app’s exercises. I had a Bolt score of 45, measured a couple of days ago, up from 20-25, measured a few months ago. Most of that increase is from other means, practices and half remembered OA exercises from YouTube videos. I wish I could depend on this app! ### 3/5 — Open app *2025-01-19, version 1.1.4* The content is really amazing and the exercise but doesn’t work very well. Very often say something went wrong and been trying to get I with the password and also doesn’t work. Constantly issue with it. ### 2/5 — Can’t log in *2025-01-17, version 1.1.4* The programs and instructions are excellent. But, having tried to log in and create an account, I’ve only been able to get in once. You have to login to use it. I’ve tried multiple days, reinstalled, etc. No explanation, just failure to connect. ### 2/5 — App not working *2025-01-05, version 1.1.4* I am unable to sign into the app. ### 3/5 — Great content, glitchy app *2024-12-29, version 1.1.4* The exercises and daily work is excellent. However, I went to log on and the logo flashed up and then the screen went black. Can’t access the app at all now. Running this on an iPhone 13. ### 2/5 — Oxygen advantage *2024-10-02, version 1.1.1.* The content in the app is really good but after a day of owning the app the app crashed and won’t load anything I’ve deleted the app and tried logging in again and it just freezes on you ### 4/5 — Times sometime don’t work *2024-09-30, version 1.1.1.* Hi guys, loving using the app with the daily breathing tasks. But the app doesn’t open up - When I try open it around 10am-1pm Australian eastern standards times. About 1am-3am Ireland times. I have to wait till after 1pm to use the app again. ### 2/5 — Very glitchy *2024-09-29, version 1.1.1.* The app itself is great when it works, but it’s very glitchy. More often than not it won’t even load. ## Most critical reviews (10 lowest-rated) ### 1/5 — Will not open *2025-12-28, version 1.1.7* I keep stumbling across an error message ("something went wrong"). ### 1/5 — Crashes *2025-06-06, version 1.1.6* Zero stars!! App won’t open!! ### 1/5 — Doesn’t work/faulty app *2025-05-22, version 1.1.6* Faulty ### 1/5 — Really Disappointed *2025-05-20, version 1.1.6* Experienced a live demo of the work that is included within this app. It was a very powerful experience and I was excited to get home and try it for myself. Downloaded the app registered yesterday excited to use it today and the app crashes as soon as it opens. Companies really need to figure out that this completely arose any trust you have with the public. ### 1/5 — App not working *2024-11-28, version 1.1.2* All I get is a black screen... ### 1/5 — Unable to Rate *2024-10-06, version 1.1.1.* I have tried several times, on and off over a couple of months, to log in. It never lets me in and gives no explanation. I am disappointed, as I was looking forward to using the app after reading the book. ### 1/5 — Hangs a lot *2024-09-21, version 1.1.1.* I had a lot of hope for this app. The book is great. The app not so much. When the app works it’s pretty good. But the app hangs and shows spinners in many places, trying to login, trying to bring up an exercise etc. Removing and reinstalling works but only sometimes ### 1/5 — Crashes *2024-08-15, version 1.1.1.* Great app, but it crashes and locks me out. Disappointed. ### 1/5 — Glitchy app *2024-03-10, version 1.1.1.* I love using the app when it works. Problem is, it seldom works. ### 1/5 — Something went wrong *2024-03-10, version 1.1.1.* Great app if it works. Had app for 3 days and it was great. Then haven’t been able to use it since as it keeps crashing and getting the message “something went wrong!” Please fix this ## Most praised reviews (10 highest-rated) ### 5/5 — Grateful for this amazing app *2025-06-14, version 1.1.6* I am incredibly grateful for the support I’ve received from Patrick McKeown. His guidance has truly helped me navigate my struggles with anxiety and insomnia. I also deeply admire his generosity in providing such a useful and effective app for free. His kindness and dedication are truly inspiring. ### 5/5 — Game changer *2025-05-25, version 1.1.6* The breathing programmes contained in this app are absolutely astonishing. Easy to follow in their natural simplicity and therefore a complete revelation. The abundant scientific and practical information that is provided makes natural sense and reveals the most widespread and common misconception and upside down teachings about breathing. I know this by how quickly and deeply my breathing has changed bringing with this heightened focus, clarity of mind, greater freedom and capacity of breath and calmer nervous system. It is 'simply' wonderful! ### 5/5 — Not working for me *2025-05-20, version 1.1.6* I’m trying to create an account and it’s not working. 🤷🏼‍♀️ Update: It’s working now. I can’t wait to try it out. ### 5/5 — Just science (no esotericism), modern, userfriendly *2024-12-19, version 1.1.4* Great app for breath work (if you want to relax, fix the quality of sleep, bring yourself to focus) Nice music, nice voice, clear instructions, easy to follow Thank you! ### 5/5 — great app *2024-11-07, version 1.1.1.* Very useful breathing technique ### 5/5 — Thanks *2024-09-01, version 1.1.1.* Great app Thank you Patrick .This app improves my quality of life immensely daily and continues to improve in time. I am an asthma patient who could not walk for more than 3 minutes without stopping for a breath . My pulmonary doctor recommended an inhaler, but I thought to research options before becoming drug dependent. yesterday I in walked 2 hours stopping only to take photos and enjoy my natural surroundings. If you have a breathing disorder, or not but are a mouth breather who will probably develop a disorder, I am convinced nose breathing is essential for good health. The science is solid. I spent many many hours understanding the process. Check it out yourself . Needless to say, I won’t be needing an inhaler. And this is truly a Free App! ### 5/5 — Thanks *2024-08-24* Great app Thank you Patrick .This app improves my quality of life immensely daily and continues to improve in time.

After a traumatic event in my life, I went back to counseling and my counselor showed me this app. I’m so thankful to her and OA. This gives me more control over feelings that can quickly feel out of control. I’ve passed this on to everyone, I know, including my little nieces and nephews this should be taught in schools, considering today’s world. ### 5/5 — Simply Fantastic *2024-07-22, version 1.1.1.* The OA app is absolutely superb and a gift to us all. Highly recommended ### 5/5 — DIY *2024-07-15, version 1.1.1.* This is a surprisingly comprehensive guide to systematically improve breathing. I read The Breathing Cure and wanted a way to implement the information in that book. So far I’ve found it in this app. After 2 months my breath hold time has increased and my sleep is starting to improve. This app is packed with exercises to follow for the motivated learner.
