A lot of commenters here are missing the point. “Addictive to use” is a bad thing. It’s not the same as “user friendly” or “nice to use”. Tech companies are widely criticized for designing apps and products that subconsciously glue you to the screen. You get small doses of serotonin from clicking on shiny buttons and switching playful toggles.

Ideally, you want a device that gets the job done efficiently and intuitively, so that you can then put the device away and get on with your daily life. With the amount of eye candy that Apple products have, with all the badges, and toggles, and pretty icons, you are subconsciously encouraged to keep playing with your device even after you’ve completed the task for which you took your phone out of your pocket.

Stock Android devices are better in this regard, because their design language is much simpler. Material UI design is flat and doesn’t feel as “nice” as Apple design language, but it’s efficient and doesn’t contribute to your addiction.
