I love the meditative aspect of this app. The narrator has a very soothing voice. It has helped with my breath hold time significantly. However the double-tapping doesn’t always work and sometimes exits out of the session. That gets frustrating. I’ll keep using this app and have recommended it to my radiation oncology team as I think it would be beneficial for anyone getting the type of treatment I am both for longer breath holds and remaining calm. **Developer response:** Thank you so much for the feedback! Will do our best to fix your bug and all the best with the treatment. ## Frequently asked questions about Freediving & Breathwork | DEEP ### What is DEEP?
