The user interface and graphics are impressive, but unfortunately, without a trigger control or horizontal time rate (sweep), it's not that useful as an oscilloscope, however the frequency domain (FFT) portion is usable without triggering or sweep adjustment. Due to the limitations of the phone mic/line input, it's only good for audio frequencies.

This is not an oscilloscope. There's no option to adjust the sweep rate. It doesn't even indicate what that sweep rate is. So, if your signal doesn't happen to sync up with that, whatever it is, then you can't determine anything about your signal at all. Anyone who had ever operated a real oscilloscope would know this.

This app does not seem to be all that responsive. It seems to simply do more bouncing, rather than following a realistic action. I use audio apps to a great degree and I am very familiar with how the display should appear. Close but no cigar. 🤔😉
