THIS APP WILL TUNE YOUR STEREO SYSTEM TO PERFECTION, OR PLAY A SWEEP AND PUT THE PERSON'S SYSTEM NEXT TO YOU TO SHAME PERFECTION THAT IS SO SIMPLE USE!!! This app is the best. 5 stars!!!! How could anyone give this app 1 star? The only way I can think of is either, they have no idea what they're doing or how to use a phone. Or they literally have absolutely know idea what a tone generator is or even used for! I now have 4 W12D4 12" JL Audio subwoofers with 4 Alpine MRP-M1000 amps. Perfect for tuning the sound settings for gain, bass boost and crossover on my amps. I ABSOLUTELY LOVE THIS APP FOR TUNING MY STEREO SYSTEM.

Still very awesome... Here I am, still using this all but a year later. This application has grown a great deal in features and complexity, yet it remains so easy to use. This tool has become absolutely irreplaceable in my toolkit. I have used it quite a lot over the months, and have every intention of donating. Thank you for building such a useful application, without any adverts on this app either...

Forgot the white/pink noise background playback I was so excited when I saw that you made background playback supported but I really only want it for the white and pink noise gens. I paid for this just because I play with it so much. Would totally put 5 stars after that's implemented.

Amazing. Love this app it's addicting! But when you move the slider it plays the sound for about 3 seconds and at the same time you move it, interfears with the other sound. Overall awesome app love using this in class. :)
