You don't have a lot web apps on mobile because the mobile web browsers provide a worse experience compared to native applications, unlike Electron or Chrome on Desktop that provides a much better experience in general (unless you have a 10 years old hardware with very little ram or are into old school GUI I know).
The companies making web browsers and mobile operating systems are the same companies making native applications stores and requesting 30% of the revenue, so they don't have any good reason to make web applications better. They are not non profit.
