I found this works best for car audio in my opinion.
Nice tone generator and more.

Could do with export wav / mp3.
I like to play noise and tones on top of other sounds playing from my phone, so it would be wonderful to have a feature that would allow me to set the volume inside the app, independent from my phone's volume
I've tried so many different tone generator apps and this one takes the cake. Super simple UI, love the explore feature with course & fine adjustment. Works great on all my android devices.
Everything works fine, except, closing the app down, it always shows on my phones pull down menu after using it, until I restart my phone(or use a kill process app).
Does JUST and EXACTLY what I wanted it to do. I'm an Amateur Radio Operator who runs RTTY (Radio Teletype) and I need access to a tone generator so I can tune-up my equipment. K2EAA
Does everything I need for calibrating headphones with sine sweeps and brownian noise. Also fun to play around with.
I really like the flexibility of this app. I especially like the presets, so you can easily go to the standard frequencies, and then use the course and fine adjustments to zero in on a particular frequency. Nice job.
Limits only to human audio range... useless if u wanted to use it on post 20khz
Extremely useful for stereo setup, and brown noise is a great sleep sound.
This is absolutely awesome I can dial my system in perfect to figure out my loudest tone and download songs at that Hz perfect
Thanks
I used it with a frequency counter and the precision is just about +/-2hz at 20khz (square wave)
An excellent program for adjust the VH audio
App is missing a common, critical capability: volume/trim control.
No option to exit the app...
No left/right control
Sooo muuuch fuuun!
Solid basic tone gen. Coarse and fine tuning allow you to home in on problem frequencies. Noise warning is also good design. Highly recommended!
Awesome app. There's a pop sound whenever I change the frequency. Would love to see (or hear. Ha!) it fixed.
Can't quite give it 5 stars due to the pop that happens when you stop a tone that's playing. Fix that and it's a totally solid 5!
Simple and elegant. Nothing gets in the way and it just gets on with the job of generating sound frequency waves.
Exactly what I needed.
This is better than paid apps. I work in an audio warehouse and our hardware sweeper died. This was great in a pinch. It allows me to sweep manually, smoothly without constantly spinning my finger.
