Launched new App in the Play Store, any tips?

Hello makers! I'm thrilled to announce I just released the Android app for my traveling project Destinfo, which allows people to access travel guides for free for anywhere in the world. You can get it here: https://play.google.com/store/apps/details?id=com.destinfo So what's next? Where should I promote the app? Any useful checklists for this kind of launch?
