I’ve done a lot of freediving training and your app is now my fourth breathing app on my phone, so I may be an outlier, but in trying a few exercises in your app, I found that it was going way too quickly and causing me to over-breathe (hyperventilate) and get light headed. I played with the settings a bit and, while it helped, it was still nowhere near the right timing for me.

It’s interesting and beautifully done, but unless there’s something I’m doing wrong I’m afraid it’s just not usable for me in its current form. Perhaps there could be an advanced setting tucked away that let me bump up the exhale and hold times to prevent over breathing?

Maybe not the most useful feedback, but I’m always happy to see more apps in this space and I’d love it if this became part of my routine. And, as a side note, some information about what Lungy Deluxe actually adds would be useful to know if I want to unlock it.
