There are some good points to this app but it could also use some improvement, I tried a few binaural apps, but I connected with about 3 of them, this is one of them. I connected well with the frequencies so I feel the frequencies are very good, I don’t know if it’s really doing anything but I find it very soothing so I don’t really care if it’s doing anything else, but the mixing sounds could be a bit better quality and the addition of good quality soothing music would make a 5 star app. At first I thought it was a little pricey for an app without a lot of feedback so I took a chance, and as I said the frequencies are really good and there are no adds and no subscriptions which is great, but I found it worth it, to me anyway.
