Thank you! Exactly what I've been looking for. Can you now let me sequence several of these in a row? Setting "each set" and duration to a "memory" to play? Kinda like an auto dialer for dtmf (touch tone phones). And As many in sequence - memory - in a row as I want...also so I can drag the order of "the memories" around? Thanks.

Better than the other GOOD one I downloaded The dials are great. If you mess around with them / see another app like this that doesn't have all the options this does - you'll appreciate this one muchhhhh more. -PERSONALIZED statement / opinion here. Absolutely no outside influence dictating this post. Only for downloaders knowledge of my true opinion. - trust me, this one seems unrivaled.

Great! This is the only signal generator that can generate 3 signal at once. I would love to see more option recording and such. thanks much!

Russell Ambeault

Interface is awful I can't believe they'd program this with crappy dials. It's just plain stupid. Makes it useless.

Only 1.2 MB App, and it is of 'Must Try Once' catagory Playing with this Application is fun; and this would also remind you your High School Waves & Oscillation fundamentals, that we might not have understood at that point of time but shall be able to appreciate after experimenting with this app .

Kim Son Huynh

Very simple I use this for burning-in headphones and such. Would like the sound to stay on when the screen is off though and an exit button to turn the app off completely.

Really high quality I used two seperate analyzers and the frequencies were spot on, not . 02 away but yeah you guessed it, .00 This is a free app but even if money was paid it needs to get the 4-5 just because trig and calculus are ancient history as far as me and school. Get it guys and you beautiful womenz that make me so crazy and fall in love 3 times per day, more of in at a crowded place. czar review for giving us the opportunity for the access.

Emilio Pirotti

Very good, interface may still improve Excellent app, although I found the dials a bit uncomfortable to use. Also understanding what waveform is being generated is not straightforward, the user interface could be made more readable.

Sue Mount

Great app Would be even better with a timer

This is a great app! I really appreciate the benefit of playing 3 different tones at once! I would love it so much more if I had the opportunity of playing even more tones at the same time with the option to save certain combinations & refer back to them without having to reset a whole combination of tones all over again; also be able to export or download my desired created tone combinations!
