Show HN: I built the stock market research tool I wanted

Hey everybody, last year my friends and I got fed up with the lack of good mobile market research tools.

We started building the tool we'd want to use, and it spiraled into a pretty sophisticated iOS app. We launched it 2 weeks ago and are feeling pretty good! I'd love to get HN's thoughts on it too.

Tech stack:

Postgres + Redis + Node + GraphQL (Apollo) + React Native + Expo

Would love to know what you think, thanks!
