Please do not be concerned as this is by no way a security risk to you. We do not query the 'identity' of your device - just permission to monitor the 'state' of the device in case of an incoming call. This is because we have a setting which allows you to decide whether the tone generator should automatically stop when you receive an incoming call. SECURITY NOTE: For your peace of mind we only ask for one special permission from your Android device (Phone calls: Read phone state and identity - READ_PHONE_STATE). Please get in touch if you have any problems, spot any bugs, have a feature request or need help. Generated waveform display (not simulated!). Custom frequency selection from 2 Hz to 20 kHz. Multiple wave forms: Sine, Triangle, Square and Sawtooth. Real-time generated signals for sound engineers to test equipment.
