[Free] Dedicated to cars

I’v done two apps, both are dedicated to car enthusiast. I would like to receive honest feedback from other developers what my apps lack most to get it off properly. In my first app I started from simple wallpaper browser, and now ended up integrating comments, rating, sharing, notifications on new content and etc. But none of my efforts really made some difference to get it off.

My wallpaper app:
https://play.google.com/store/apps/details?id=com.stancedcars.wallpapers

Youtube streamer app:
https://play.google.com/store/apps/details?id=com.racing.movies

I simply would like to get your feedback if possible :slight_smile:
