Comments on Signal Generator for Android

★★★★★ A Google User · Nov 27, 2013

Works for me... Pink noise beats crashing waves any night. Small app for a nights sleep...priceless.

★★★★☆ A Google User · Jul 24, 2015

Great, free signal generator. Very limited functionality but as a simple single tone generator combined with white and pink noise for audio system testing - it's great value for what you pay for it - ie nothing.

★★★★★ A Google User · Nov 11, 2013

Great for quick tests. I ran some very quick oscilloscope tests, and it can provide a sine wave 20-20kHz, accurate to 2SF, the third SF is ±1 of the true value. Do not use this app when charging. If you do, there will be a rather lovely 50Hz signal overlaid on the output. At higher frequencies it's not an issue, but at lower frequencies the interference is very noticeable, and at an output ~50Hz produces a lovely beat frequency. Remember that your android device is not designed as a signal generator, therefore the output is not going to be as clean and perfect as a real signal generator. Different devices may produce different results. I recommend you test yours with an oscilloscope where possible.

This app is a spyware, it is accessing your photos, files and your contacts!!!

★★☆☆☆ A Google User · Feb 15, 2015

Poor low freq access range These graphs leave little wiggle room for low freq ones. Maybe only 1/10th of the slider scroll is dedicated here. Above 2khz, is okay. Below it, u have to type the desired freq, if u likt to play below 2khz,a lot, u will have a devil pf time tweaking as there is little scroll range dedicated here, go elsewhere

Fair to poor. Very frustrating this app will turn your volume all the way up can blow speakers be careful. Also needs ability to run in the background.

★★☆☆☆ A Google User · Jan 21, 2014

Be careful For some reason this app turns your phone media volume up to 100% regardless of setting and leaves it up after. I've been deafened a couple of times when I go to listen to music after.
