I am on the fence with this app. I love what it does. It works. It has helped with my headaches. However, there is no exit button for the app. I cannot shut it off & get out of it. I need to shut my phone off in order to close it. Not cool. It runs even with a phone call. There is no volume button either. The tones are great & do what they say, but very little navigation within the app. That is why it is a three. Tones are 5 stars. navigation, volume & exit are 3 stars. Samsung 3 flip phone.

Thanks for the feedback! We're glad it's helping with headaches. To close the app, swipe up and hold to see open apps, then swipe Z-App away. Volume is controlled with your phone’s side buttons. We appreciate your suggestions and are always working to improve!

I love the ability to build your own playlist, as well as the ability to customize how long each frequency plays. I'm using it for my dog's lymphoma and my inflammation. I would like the ability to sort the Frequencies from low to high and high to low so that I can play more audible tones while awake and more soothing lower tones while sleeping. Otherwise this is a fantastic app and I just can't recommend it highly enough. Thank you, thank you, THANK YOU !!!

Love this app. There's been a lot of research on the healing properties of sound/ resonance/frequencies of late and, FINALLY, something suitable and portable for those of us who cannot afford a Rife Machine! I have no complaints. You can use earbuds and go about your business/work without issues. I find the tones/frequencies soothing to listen to in the background. And, OF COURSE, being in the moment in a relaxed mood is where ALL HEALING BEGINS! I just downloaded the latest Update of this app.
