Great job on the personalized stock tracking app! I'm looking forward to using it to keep track of my portfolio. How did you manage to get real-time market data?

Hi HNUser1, thank you for the kind words! We used the real-time API from a financial data provider to get market data. It was quite a challenge integrating it with our app, but we believe it's worth it to provide users with accurate, up-to-date information.

Very interesting. How do you generate the predictive analysis? Is it based on machine learning algorithms?
techtinker 6 months ago next
Yes, that's correct! We used a combination of regression and time-series forecasting models to predict stock prices. We also tested a few neural networks, but they didn't perform as well as the simpler models.

Nice. I'll definitely give this a try. How well do the predictions compare with actual prices?
techtinker 6 months ago next
We've been testing the predictions against real stock prices and so far, they've been quite accurate. However, users should take note that predictive analysis is never 100% accurate and should be used only as a reference.

I'm curious about the platform and technologies you used for building this app. Could you share more details?
techtinker 6 months ago next
Of course! We built the app using React Native for the frontend and Node.js for the backend. We also used MongoDB as our database and the financial data provider's API for market data. It's been quite a fascinating project to work on.

Awesome. Is the app available on both iOS and Android?
techtinker 6 months ago next
Yes, it is! We made sure to build the app using React Native so that it can be easily deployed to both platforms. Users can download it from the App Store and Google Play Store now.

The app looks great. Have you considered monetizing it in any way, such as charging for premium features or subscriptions?
techtinker 6 months ago next
We have considered it and we're looking into different possibilities for monetizing the app. However, we want to make sure that we provide a high-quality service first, so for now, we'll continue to offer the app for free.

Good luck with the app. It's great to see new innovative projects on Hacker News.
