Review summary

Users praise the app for its easy, private, and reliable operation, plus usefulness for testing speakers and DIY amps. They appreciate background playback and the free, lightweight nature. A recurring concern is device-dependent high-frequency distortion or aliasing, suggesting hardware limitations rather than software flaws. Some minor feature requests exist, but overall feedback is positive.

Pros

Easy to use and intuitive UI
Privacy-friendly: no personal data collected and no cookies
Reliable performance with background playback
Free/lightweight with no unnecessary bloat
Useful for testing speakers and DIY amps

Cons

High-frequency distortion/aliasing at frequencies above ~10 kHz, likely due to the device hardware rather than the app

2026-08-19	Ca*****	Awesome EXACT sound that would be emitted from AI Data Centers, for anyone who is concerned about this... Download this app, then launch the "sine" sound waves at a frequency of anywhere from 10-60 Hertz at your local municipal council meetings... they'll get the point that this noise is EXTREMELY detrimental & dangerous to humans & animals!!! SPREAD THE WORD!!!
