I have a lot of apps on my phone. When I switched from IOS to Android I found most of the same apps by name. The few that weren't available on Android I was able to find replacements by other vendors that worked just as well. You just have to search the store. As of today, there are 700,,000 apps in the Play Store, same number as in Apple's store.
You're never going to find everything the same and that's always been the case going back to the beginning of the micro computer days when you had a variety of operating systems - Atari, Commodore, CPM, TI-994, Amiga, etc. To me it's a good thing there are some differences between platforms.
As I said in another post, IOS and Android boil down to individual preferences. I'm able to do so much more with an Android phone that I ever did with my iPhone. But I'm sure there are others who will say exactly the opposite. That's the great thing about having choice - hopefully there is a platform out there that works the way you do.
