Something isn't right on Android since the update 10/19. I can only play one tone at a time. I have the paid version and can't use it the way I had before. Can someone help? Update 1/2/2019: I see you updated the look of the app. However, the check boxes to select multiple tones to play at the same time are still missing. I've contacted you again through your Customer Support page.

Annoying ads are OK. BUT when I exited the app, another ad was popped up in my browser suggesting further actions to take after the installation. To much. Better use non-ads app with lower stars.

I love this app on my IOS system but this one on android doesn't suit my needs. This is very disappointing. I need sample rates from 32000 all the way up to the 192000. You can do on the IOS version but this is not possible with the android version. If this was avaible I would change my rating to 5 stars but because it's not available I can't use it so it's a 1 star for me. I look forward to being able to use it thank you for recommending the change.

Works well. Would be nice to be able to upgrade to a "non-ad" version on Android (the pay-to-upgrade button doesn't work), but otherwise it's a decent app. I use it for instrument tuning.

My screen froze for like 2 minutes then I click the X to remove YOUR AD and it clicks on your ad. Ugh. Start over. Same thing. Bye.

So I have read that this software was used in the binaural and monaural beats study which makes me trust it far more than other apps. Thanks for the Android app too!

Note buttons don't work. Plays the same tone.

Easy to use and lots of options

This is actually true to it's harmonic frequencies that I have come across since my research began, keep up the great work guys

A simple app that simply works as described.

can we have a update above 200,000 HZ ?

In my R&D of tinnitus modelling, the Mac version is great. Now I have it on my Android phone for demonstrations on the go! And for my youngest daughter who is noisy, kind of levels the playing field then :)

Would have given 5 stars but only allows landscape mode on Galaxy S5. Other than that, works great.

All it needs is a timer for each frequency.

The interface isn't particularly intuitive, which is my primary gripe with this app. If I want to only play one or two tones out of three I've programmed, I have to delete the ones I don't want to use, rather than simply mute them, and then reprogram them to bring them back again. On exiting, I was redirected to a website; it might have been benign, but I still object to that redirect. It has advantages over similar apps, such as accepting decimal values entered for Hz.

this is good physics model on frequency... its good

this can do a lot of cool stuff

Apparently for a large tablet.

I can't purchase it

Very educational. This tone generator shows a frequency that my family doesn't know about and educates them. Thanks NCH Software for making this educational app.

A separate volume control seems to be a glaring omission. Individual volume for each tone would be great
