This is hands down the best frequency generator app that I have ever used on a phone. Well worth to cost for pro. However, the newest update while it looks great. The one thing I need the app to do it no longer does. And that is it no longer continues to play in the background, nor does it continue to play when I switch my screen off. This makes this app virtually useless to me. I'm hoping it's just a minor glitch that can be easily fixed. Until then, I will not be updating on my other devices.

A very well-thought-out audio test app. Developer is responsive. Edit: still my favorite signal generator app 7 years later! Quality product. Edit 2: I purchased in 2013, so I've been using this signal generator for 11 years now. After purchasing, I needed an inverted polarity noise signal to detect speakers with incorrect polarity wiring. To this date, this is still the only app that does this. Indispensable IMHO. It's worth the price for the pro version.

Ad bait. Only a test to bait you to buy it. Too incompetent to sell something with the price so wastes peoples time tricking them with a fake free product that doesn't work fully

Just too many forced adds and way too expensive. The app has good functions but is close to unusable for free and from the comments the paid version is also unreliable and not backwards compatable. Use add banners instead of full screen video ads and don't constantly pester the user to buy. Consider having a pay range like a lot of other apps do where the user can choose an amount. The issue is you're not adding a huge amount of functions over free apps and then charging a lot for them.

It Sucks. Like 30 second playtime limit unless you give these greedy devs' money. The whole play store is completely transactional and NOT WORTH IT. im going to get an a.i. app and make my own noise generator. Bye, devs. You are redundant now anyway. a.i. make one better, faster, and free. Have a good life clinging to the last fistful of money while it slowly vanishes. Along with your job.
