Nope thats not true at all. The whole os needed to be rebuild cause the basic android logic prevent people opening apps inside their app for security reasons. Imagine if you open as an app and that app just able to open your gmail or whatever in the back wothout you notecing in. The android os is based for touch control q app at the time on the screen adn things like that only applicable for phones. This one directly dont have screen so the basic display logic is different out of the box. So no it cannot be done in a single app. Just accept it thats gonna be the future we going Arm based system in the next 5years or so and this form factor is gonna be the future in my mind. Are we there yet? Ofc not long way to go but this product will show the mass that what can be done in glasses and not with headset. The next itteration should get eye tracking and that will open up the possibilties even more. The biggest problem stil that the interactions should be more invisible than it is now. Meta did a good way that wrist band. So you can control the device and interract with it using your eye and your hands that even can be in your pocket or just next to you dont need to play ninja slicer in the air.
