Installed this a while ago, and used it to find a resonant buzz in my car door speakers. I've come back to it now to test an amplifier. You can pick sine, square, triangle or Sawtooth wave forms. Sine wave is pretty clean, square is messier and falls apart at high frequencies. The phone's volume control adjusts the amplitude, I get 0.8v peak to peak at max volume. Sine wave amplitude is reduced at frequencies above 17kHz. Very handy, simple to use. The promotions of other apps can intrusive but hey, Dmitsoft have to make a living!

Very handy for testing speakers and headphones etc. I've noticed my phones (sony XZ1) eq settings do not affect the sound, would be nice to have as an option. Also, a few more settings for the pitch sweep like total time taken would be handy. For a free app though it's great, ads are unobtrusive 🤖👍

This is the best and my favorite tone generator on Play store. Way better than Ms, Apple, or Amazon Apps.🥰😍🥰😘kk

Love the bass sweep for testing crossovers and driver matching. Could do with a full frequency sweep because it takes ages to wind the sub sweep frequency up to 14khz to make it full range.

Awful since the update. I immediately uninstalled. The app used to be very simple and very useful. Now it's riddled with ads and the interface makes no sense. Stay away if you're looking for a good simple tool.

Unfortunately, developer have eaten something wrong and destroyed the app that used to be the best simple tone generator.

Used to be great and simple, now seems to be just ads. Virtually impossible to find the actual app amongst the garbage and the back button doesn't even work to get out of the full screen takeover ads.
