Love this app! The sequences really help with many issues. I would rate it 5 with a couple of minor tweaks. I would like to see some sort of volume regulation. I am constantly turning the volume up and down as the sequences change. I would also like to be able to add a frequency or sequence into the list I am playing instead of adding it to the end. Overall this app is awesome!

Thank you so much for your kind words!That’s fantastic feedback on the volume consistency. Concerning playlist flexibility, we try to keep the sequences in the order they were created as many frequencies need to be used in direct order. Having said that, we can look into creating some flexibility for seasoned users.

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.
