v1.9 is out — now works on Windows 11 too (contributed by @SHJordan in PR #3). pip install --upgrade breathe-cli to update.

Looks nice! Thank you for sharing. It's nice to see that I'm not alone in my breatghing pursuits.

I'm wondering if you tested my app. Care to share your feedback?

Thank you for bringing this to my attention. However the purpose here is medical for a Market of One (myself), not meditation. Give it a try and share your feedback.

Submit a Feature Request with a Why :)

This is true as I've created this app for a Market of One. Having said that, if there's sufficient interest I'm considering adding other breathing modes besides Heart-Failure-friendly ones. If interested, open a Feature Request.

Thank you for asking. I've been building for a Market of One --- i.e. myself (heart failuer). Research shows breath holds are not recommended for my condition. Having said that, I realize this is not a universal guideline. I'm considering adding other modes besides heart failure-friendly ones. What are your use cases? Would you like to submit a feature request?

Thank you for noticing my effort. I hope the app can help you. Would you like to share your experience here?

Thank you for your comment. I've never envisaged this kind of an application. Does it help you? Is there any research you can share or is it just anecdotal?
marekkowalczyk··on Show HN: Breathe CLI – Paced resonance breathing in the macOS terminal
Thank you for noticing. You've really captured the idea of the app.

Dizziness is certainly not the intended outcome; I don't get any. It's too much oxigen in your system. Ditto more shallow breathing.
marekkowalczyk··on Show HN: Breathe CLI – Paced resonance breathing in the macOS terminal
Thank you for sharing your experience. Try more shallow breathing rather than modifying the frequency/timing, which is the whole point of this approach :)

Good point. I can't see a reason not to regulate your nervous system. Give the app a try and share your feedback.

I'm wondering if the protocols that I have included with the app could be helpful in your situation. I'm curious of your feedback on the app.

In psychology there's the concept of Secondary Benefits — a behavior harmuful on the surface always has a Positive Intention behind it — otherwise an individual would not engage in it.
marekkowalczyk··on Show HN: Breathe CLI – Paced resonance breathing in the macOS terminal
What you're referring to reminds me of the concept of Biofeedback.

Indeed related! I don't have a Polar but the app looks nice; starred for future review / inspiration. Thank you.

Try `breathe` and share your feedback!

Looking at your comment and at other comments as well I think this approach is the new black, deservedly (is that even a word?). Try the app and share your feedback.

Not at this point. I developed it with the Market of One in mind — for myself. But I'm open to requests that will broaden the scope of modes for other users. I just don't want to invest time into speculative development. Try the app as-is and share your feedback.
marekkowalczyk··on Show HN: Breathe CLI – Paced resonance breathing in the macOS terminal
What do you mean?
marekkowalczyk··on Show HN: Breathe CLI – Paced resonance breathing in the macOS terminal
Hah! Nice catch. I should have thought of this name myself.

Try the app and share your feedback.

marekkowalczyk··on Show HN: Breathe CLI – Paced resonance breathing in the macOS terminal
Thank you for sharing — downloaded. I'll comb it for relevant info for the next sprint. Meanwhile, try the app and share your feedback!
marekkowalczyk··on Show HN: Breathe CLI – Paced resonance breathing in the macOS terminal
Thank you for noticing my effort. Do give it a try and please report your experience. I'm open to feedback.
marekkowalczyk··on Show HN: Breathe CLI – Paced resonance breathing in the macOS terminal
Exactly that kind of thinking was my idea for the app. A UNIX-like approach to solving a personal problem for the market of one :)

I'm tired of accounts and subscriptions. Give it a try and share your feedback!

marekkowalczyk··on Show HN: Breathe CLI – Paced resonance breathing in the macOS terminal
Thank you for noticing. Yes, I will include other OSes in a future version; I just wanted to release ASAP after squashing some weird bugs.

Give it a try and share your feedback.

marekkowalczyk··on Show HN: Breathe CLI – Paced resonance breathing in the macOS terminal
I've never thought of this kind of a use case but I'm happy you see some value in trying out `breathe`. I'm curious of your feedback after you've worked with it for some time.
marekkowalczyk··on Show HN: Breathe CLI – Paced resonance breathing in the macOS terminal
Thank you for your appreciation. I don't have an Apple Watch so it's hard to say. There isn't a ton of research on the subject — no Big Pharma sponsorship money in a breathing technique that you can't patent — so I suspect it's the same research.

Give the app a try and share your feedback. Happy Breathing :)
