Signal Generator App Reviews

the other shapes produce

Im very happy with this app for ear training, its super simple and works great. Nice job to the devs

Awesome app... Needs a programmable sweep function and it would be perfect.

No sound coming out of my speakers

While the app describes it can output 20hz-20Khz, it actually does more. We tried playing 12hz, and it worked nicely. We could, of course not hear it, but feeling it was pretty cool. Anyway, it does what it says, and is a 5/5.

Great signal generator. Does everything I needed. The UI is simple and intuitive. I only wish it had to ability to keep the iPhone from going to sleep while generating tones.

Just what I needed. The only feature request I have is up down arrows for the frequency so you can easily step through freqs without using the jog wheel. Maybe these could be tapable spots inside the jog wheel?

Frequency scrubbing no longer distorts. THANK YOU for fixing it. It makes such a big difference. Now I can use this to test audio setups at gigs, during prep or to train my ears. I hope you guys keep improving the app. The jog wheel could use refinement and so could the arrow buttons and numerical input section. Another great addition would be multi-tasking. Please keep up the good work and thank you guys.

Looked through many signal generator apps and this one had all I needed and all on one interface without being cluttered or costing too much. I have no complaints, it leaves me wanting almost nothing more.

Looks like it prevents phone from locking so it plays continuously. Excellent.

This app is messed up. The sine wave sounds as expected but the square and saw sound more like chords or hard sync tones. I ran through my oscilloscope and saw all sorts of crazy ripples. The sawtooth isnt even the right frequency. I want my money back.

Hooked to an oscilloscope. As other reviewer said, square and sawtooth are broken. Only good for sine + triangle

This app does what it says, but the wheel doesnt quite work right, at least on the iPad. It jumps around quite a bit. Also, it doesnt play in the background, which severely limits its usefulness.

Great App!!! Can you please update so it can play even why the screen is locked? Thanks

Puts out a decent signal but the knob is useless. Frequency either doesnt change or it jumps around. Ill have to keep looking for an app with continuous frequency control...or drag out my function generator.

Square wave (which is what I typically use the most for testing) is useless. And the wheel doesnt work as expected. I know I shouldnt expect a lot from an app, but still paid $$ for something that should at least be semi useful on the go.

Sine wave freqency is right on. Some 3rd order harmonics, but not bad. Square wave has lots of ringing at around 1K, but is totally unrecognizable by 5K. Same with sawtooth. Triangle is good, and the frequency is right on at 1K; by 10K it is a sine wave approximation. Comes up in A 440. Wish you could request a different particular note.

Doesnt work simple as that

Looks easy enough to use but no sound. Kind of defeats the purpose.
