Kardia Customer Insights

1. (ideas for improvement: indefinite run mode, keep running with screen locked, maybe shared/synced sessions with friends)What a great app! I recently suffered an episode of atrial fibrillation and using a custom cardiac coherence exercise I brought my rhythm back to sinus.

2. I've used several breathing apps and this is best for visualization of lungs opening smoothly to fill and closing smoothly to expell airThis app is a wonderful deep breathing tool, is highly customizable for all and totally worth purchasing! If I had to suggest anything, it would be to build a custom reminder so I maybe reminded throughout each day 2 pause and breathe.

3. Finally a cardiac coherence app that doesn't ask you to pay for the most basic features so that you don't experience frustration within the first minutes of using it.Amazing! I was going through what is commonly know in psychology as "fragmentation" and this application definitly played an important role in my recovery.

4. It would be great if there were links to additional resources like books, videos or blogs about the activity and how it works and suggested ways to use the app.Love this app for slow, resonant breathing or working with different inhale/exhale ratios.

5. I can't even use this app because the orientation mode won't lock; the screen keeps flipping between portrait mode and landscape mode and won't respond to my phone orientation lock.

6. My only question is how does the timer work? I use sound-guided mode and don't look at the screen, so I can't track time.

7. Thank you, whoever you are, for creating this.Great anchor when I'm having trouble settling into meditation, and I've also started using it while studying to make sure I'm not tensing up too much.

8. I like the gentle sound guidance so I can close my eyes & not have to watch the screen.This is the best breathing app I've found.

9. Allows self selection of number of breathing cycles per minute, as well as setting pauses.

10. Well done and thanks!Didn't expect breathing to have such a calming effect.

11. Is it designed to work like that or am I facing a glitch? UPDATE: It worked with Kardia+.Free for what i used it for.
