TL;DR: We launched an iOS app without monetization. We got some traction but now we have to prioritize: improve the product or validate the business model.
A little bit of context:
We are building an iOS app to follow eSports (League of Legends in particular). We launched and we just reach to 200 monthly active users. Our retention seems good: 40% D1, 21% D3 38% D8 [https://imgur.com/WIZt1qX] (matches are played weekly that's D8 is so high) but now we have to make a choice. We have a very limit effort and we don't know if we should invest it in improve the product (we have a lot of ideas) or try to validate the business model with an early monetization.
What do you think?
