I use Grapenen OS on Google in fine on my private one, my secondary phone is my work Phone and it is an Iphone. 

I like to call it Spy Phone, because this is incredible but the technology is long there. 

Apple has filed several patents related to brain wave reading, specifically for integration into AirPods. While these patents are still in development and not yet commercially available(lol), they outline the company’s vision for measuring brain activity using wearable devices.

Key Features:

In-ear electrodes: Apple’s patents propose placing electrodes within the AirPods’ housing and tips to measure brain activity, muscle movement, blood volume pulse, heart function, changes in skin conductance and perspiration, and eye movement.
Non-planar surface: The electrodes would be designed to be placed on a non-planar surface in the device housing, reducing visibility and improving aesthetics compared to traditional methods.
Intuitive user experience: The system would allow users to initiate biosignal measurements, such as EEG, with a single tap on the AirPods’ surface.
Multi-signal measurement: The patent envisions the ability to measure various biosignals simultaneously, including EEG, electromyography (EMG), electrooculography (EOG), electrocardiogram (ECG), galvanic skin response (GSR), and blood volume pulse (BVP) measurement.
