UI UPDATE

I’m loving the new UI update & sleek feel of everything. The app feels more alive like this. I’ve been an avid user for a while now & love the app, but a good UI update is so refreshing to have & makes me excited to continue using the app.

Tinnitus simulator

That’s right; subject to tinnitus for twenty-three years. Using your tone generator to simulate my high-pitched tonal tinnitus for those who have no idea what tinnitus figuratively sounds like. It’s close enough to convey the sensation. Kind of the equivalent of fingernails on a chalkboard.

Good but could be great!

I use this app quite a lot for frequency healing work, etc. I find Di very useful and feature rich BUT - I struggle to read the names/ titles of frequencies when using on my iPhone. It would be a great advantage to be able to give frequencies custom names that may be entered in BOLD! Also along the same lines it would be really helpful to be able to change the order of the frequency list!
All that said it’s a very worthwhile app.

Great tool but unpredictable and unreliable.

I used to love this app until time went by, and more and more features were removed and became only available to paid users as updates were made. Of course they never mention that in the new versions/releases before you download them. Pretty deceiving and unfair to the original users.

Left and right speaker switches do not work!

The left and right channel switches do not work. When I set a frequency to play on the left speaker it plays through both. When I set a frequency to play on the right it still plays left and right. I paid for the pro version of this app and I would expect that to work. Just needs a fix and I can give the app the positive review it would deserve.
