Help get more users for new social media platform

We pit out a really fun and engaging social media app last month, and are looking to get more users. We have been gaining users steadily since we launched, but are looking to target a greater variety and more pockets of people.
For every perosn that you get to download and use the app you get $5. This is up to $200 so 40 people. The app was designed for close connections like families communities neighborhood's etc. Everyone counts parents siblings uncles aunts neighbors community members etc.
