Good app Very nice app. One thing lacking is the ability to play in background and or with screen off which would be nice if u intend to use for infinite hours data grinding the whole audible spectrum indefinetly and then some, guess ill have to get a another phone exclusively for this app. I love the sweep feature. The burst feature is a little time consuming to use. Very education useful helpful fun app A++
Works great for my purposes. Here are my few observations. I've built a microphone opamp circuit to pick up the sound wave from this app. Sinusoidal signal passes really well, square and sawtooth signals barely recognizeable. It was expected, because the signal has to pass through the smartphone speakers, then through the air, the microphone and my circuit. If I connect the outputs directly to the oscilloscope, all signal shapes can be easily recognized. The frequency was not very stable, jittered around +- 3Hz, but that was good enough. The amplitude noticeably rises with the frequency. This can be heared by ear.
You're kidding, right? Works perfectly, free AND no ads? This app breaks the infamous "Pick Two" rule of mobile apps! As an avid amateur electronics DIY'er, this app does everything I need it to for my projects and more without needing to buy a $6 million signal generator to take up space on my workbench. Did I mention it's free and has no ads? I did? Good, well, I said it again. You guys are awesome.
Best function generator I could find Pros: dual channels, lots of options (including duty cycle); cons: can be confusing (sometimes I have to reset the app in order to make it play again), controls small. It would be nice if it was a bit more phone and user friendly.
This app is so good it exposes the lousy capability of your cell phone's D/A converter! Whereas you need an actual function generator for dead clean waveforms, this app is beyond handy if you need a source in a pinch. Fairly capable assortment of modulation tools, and one shot options. Room to store your own presets too. And not only is it free, it's Ad free!
Played for an hour on this thing Was not what I came to the app store for, but I was curious by the app image and downloaded it. Was pleasantly surprised by how long I would go on to try to learn how to use it, what the different results would be by toggling different settings. Was enjoyable. I'm sure it has more utility to someone who knows what they're doing more than me.
Added settings (cogs button top left) - Frequency, Amplitude, Phase and Duty Resolution can now be changed. Settings also has a soft turn on/off option to avoid those annoying 'clicks' . Added a short user guide (i button top right). Plus a few more minor tweaks/fixes.
