I often use an audio signal generator on my cell phone at work.
The generator is online and no registration is required.
It generates signals with different waveforms, such as triangle, square, sine, and sawtooth.
The generated signal ranges from 1Hz to 20kHz.I use it often so I don't have to carry a signal generator around to check the signal, and I find it quite useful in most applications that only require a low-frequency signal.

To use it, all you need is a jack connector that fits into the cell phone's headphone output, connected to a pair of alligator clips. It's recommended to use a small transformer to protect your phone.
