That's 90% of non-game apps. Most apps could be written using web-based tech (React Native, Flutter, PWA, whatever), and because they're so simple they should be very fast and very small. Where an app that's a few toggles and animations is slow or janky it's a sign that the developer screwed up rather than a problem that would be solved by going native - the dev would screw up regardless of the tech they used.

Some apps that have extensive design or animation work benefit from being native, and there are some things that are painful to do using web tech like custom camera work or things that use the secure enclave in weird ways, but if you're not doing those things then web should be fine.
