Indian IPO Info App & Site along with Google ads monetization

I need a production-ready solution that presents comprehensive Indian IPO data across three fronts: an Android app, an iOS app, and a matching website. All three must stream real-time IPO updates straight from reputable market feeds, let users browse historical IPO performance, and allow them to set up customizable alerts so they never miss an allotment date, listing day, or price change.

On mobile, push notifications for the alerts are essential, and the interface should follow current Material / Cupertino guidelines so the experience feels native on each platform. For the website, secure user-account management is required so watch-lists and notification preferences stay in sync with the apps.

Please set up a single code-base or clearly documented repositories for each target (React Native, Flutter, or any equivalent modern stack will work) and supply step-by-step deployment instructions along with the finished builds.

Also both the app and website should be monetized with Google ads.
