What kind of android app able to drive downloads?

Understand that google play store is now saturated with lots of apps and games.
I have released a few apps recently and they are driving only a few downloads per day.
Which kind of android app do you think can still drive downloads?
Thank you.

Exellent question !

Something quirky and different. People change their play habits all the time, what type of game that was popular one week might not be the next.

Other then that if your game isn’t where people can see it then they can’t download it
