Which channels are my users from?

Hey Indie Hackers, This is Haaji from iweydii.com we are now in the stage of launching our app to the public, we wanted to track where are most of downloads coming from? is it from that influencers page that promoted our app on fb? or was it my email list? or friends sharing my app with others? simply put how can i track these links? google play store developers says 'third party referrals' but i want to know which link generated more installs.

Thanks for your time
