I quite like this app, the developer did a good job. I would have given a 5 stars if this app had the following features: - the ability to stabilise the signal on the waveform part (like an oscilloscope - maybe just have a switch to toggle the oscilloscope function on/off) - ability to choose the source (microphone/input source) But as I said, this is already pretty good and I would gladly pay for an app like this.
