When two entities control essentially the whole "market" for mobile OSes and associated app stores, and use their position to force their app stores on everyone, you no longer have a market. If we just forcibly split Google and Apple into smaller companies with separate app stores then maybe we could see what markets would do.

Third party app stores exist, and they work on android.

But the problem is that when everyone has gravitated to the two biggest app stores, there's no scope for market competition. The point is not just to have third-party app stores, it's to not have huge app stores that capture the whole user base.
