> There are certainly tasks that are best done by a phone or mobile app; usually, these are things that involve moving around, such as navigation, or depend on phone sensors, such as working out which way is "up". But nearly everything else can be done by a website. Actually, both of those things can easily be done in a browser app. About the only thing that can't be done easily on mobile right now is GPU compute shaders. But that will also fall when WebGPU merges from desktop browsers. The only other thing I can think of is generic, system-wide file management. That probably won't ever be coming. Though the File System API does allow users to grant access to specific directories, I don't think the permission persists past a page reload.
