It is the "why use python" for mobile.
The native apps will definitely be better in terms of performance and UX. However, having 2 codebases means twice the tokens.
I came here to say this. I also prefer fully native apps but this is the elephant in the room. If most of your web code can be re-used on native, that's a ton of tokens you won't have to pay for.
The problem isn't tokens but verification that the code works.
