Helpful thanks
It's not cluttered with eye candy, it only does one thing (exactly what it claims), nothing more, nothing less. It's free, no ads, no BS. It's USEFUL for lowering my heart rate. I recommend it to my friends. I have only one question. WHO DOES THAT??!!??!!?!? Thank you and WELL DONE!!
Wow this app exceeded my expectations!
Simple but amazing
Simple, ad free, customizable breath timing, just perfect.
It's the survival of the human life ,calm the anger and build patience with time.
Just add background sweet sound for inhale and exhale and make this app 5 Star. I will give it this app 5 star then. Very good app.
Awesome
Relaxing
Being able to edit the in and out is really handy for stimulating the vagus nerve
