Free and amazing

Thanks to the people behind this app, in a world where health is monetized, to have something that great for free seems surreal, I am truly grateful to you guys.

Potential but not there yet

This app has some potential but it's not the most intuitive setup. Haven't figured out how to clear the player. It just keeps adding more frequencies and insists on cycling through them all. I feel like there needs to be more "how to" explanations or perhaps I'm just missing them? Kind of frustrating.

Love it! Highly recommend.

Thank you for creating this app!!! I love this app. I’ve found it to be very beneficial. I wish there was a way to change the order of the frequencies from time to time just to change things up. Also, I don’t know what the arrows on the right are for or how to use them. A few instructions to maximize the use would be great…

Please fix bugs

I love the service you provide in this app but since the last update it is more glitchy. The repeat doesn’t work, and if any other sound happens to come through the speaker (i.e. a phone call) then the app no longer plays the frequency even though the timer continues. Stopping the sequence and restarting it doesn’t work either, you have to close out the app and restart it. It gets frustrating when you are halfway through an hour long sequence and then have to start it all over again. Please fix

Not working

App not working with iOS 18

Doesn’t stay on

I like a lot about this app and am grateful it exists BUT if it’s running and you get a call, or an alarm you’ve set goes off, it doesn’t emit a frequency afterwards. I find myself in the middle of a sequence having to start over from the beginning. If you can’t fix this then please find a way to restart in the middle of a sequence.

Please

Could the developers please add a further to where we can press play on My Zapp and all of them will play in order, it’s pretty annoying pressing each of them all the time when I try to use the app.

Totally shocking

I found out the key to some of the things that I was experiencing was thyroid related dealing with arthritis. So I tried this because I know the benefits are frequency on the body from being a kinesiology major. The first night I used it. I woke up the next morning and was able to get out of bed with no pain whatsoever, my low back didn’t hurt my knees. Have been using it for a week now and I’m totally shocked at how much better I feel.

Not working on my I phone

Worked once then no more sound. Uninstalled and reinstalled it no sound but the timer is going.

What happened to 396-417?

These frequencies were in use and just stopped recently?
