The method is life changing, I do 3 rounds almost every day and have benefited tremendously - stable mood, a better handle on my depression, increased motivation, increased cardio output, increased confidence, I feel more youthful. The benefits are innumerable!
However, the Apple Watch app is in dire need of improvement and why I gave 3 stars. I got an Apple Watch for Christmas, and after putting in over 9 hours of retention time on the iPhone app, I was looking forward to using the Watch. The idea of simply tapping my wrist to start and stop retention time is fantastic! Unfortunately, the Watch app seems independent from the iPhone app. No options for music customization, nor can I expect to choose the amount of breaths or the frequency (slow, medium, fast). This is quite a let down - guess I’ll be continuing to bend my neck to find my phone and double tap to enter retention mode for now!
That’s all to say, please update the Apple Watch app to make it more in line with (or even linked to!) the iPhone app. That would make my year!!
The iPhone app itself I’d give 4 stars, as improvements needed are few. Mostly it’s fantastic, and I love all the customizations! I’d like the option to add or remove Wim’s voice on top of the breathing music, as I was used to him being there with the music and in a recent update his voice is gone.
