IMO, roll your MVP with something like React Native, although it all depends how important the user experience is for your end users. Snapchat built with some platform-independent UI toolkit would have felt kind of wrong, and the speed at which I've seen teenagers use it (this was years ago) shows that they would have been frustrated with anything that is slow-ish. I assume similar trends dominate for TikTok and Instagram today. So unless you're attracting a very hip, fast-moving, perhaps even young-person's market, you probably just want an app that basically works and is available to folks on whichever phone they use. React Native, Flutter, Xamarin / .NET MAUI will all get you there.
