A free app for Android, by Alex K.
The Android AR-Oscilloscope app for Android and PC allows you to visualize an electric waveform. It can also be used as an accelerometer to measure your movement.
The app will display the waveform on your Android device. You can select from a list of available functions and modify the settings to fit your needs. You can change the display to see the waveform in real-time, as well as change the volume and the frequency. You can also save the waveform.
This app can also be used to make an audio recording of the signal. It can also be used to measure the frequency and the min/max value of the signal.
