Signals Generator is a free iPhone application that transforms your device into a versatile dual-channel signal generator. It is designed for creating sound signals, and professionals can utilize it for audio electric signals as well. The app offers a variety of signal types, including sine, triangle, sawtooth, and more. Users can easily switch between single-channel and dual-channel modes, adjust parameters like amplitude, frequency, and phase, and zoom in on waveforms using gestures or buttons. Moreover, the app supports interface color selection, enhancing user experience.

Professionals should note that the app can be used for circuit measurement, with audio signals output through earphone channels. However, caution is advised, as high-voltage circuits require proper isolation equipment and professional knowledge to mitigate risks. The developer emphasizes that any losses resulting from the app's use in circuit measurement are the user's responsibility.
