Patni1, This is a much bigger question. I would evaluate whether you go Android or Apple IOS on many more things than the BMW connected app. I am Apple, works fine. I suspect the Android version is exactly the same...
You are about to make a life changing decision
- go Apple where everything just works, designs are fab BUT you are “locked” into Apple and definitely pay a premium
- go Android where you get much more choice, because it is more competitive between manufacturers it is cheaper. Probably (as I am not Android) slightly different experiences across devices, slightly less consistent user experiences and slightly harder to connect and configure everything - so probably need slightly more technical ability.
My 72 year old mother has embraced Apple (Mac and iPad) and needs very little help from me - so a great benchmark on simplicity !!!
