How to make a text only browser for iPhone?

I read on internet extensively.I use violoncello app to access this and other websites. This named app is a text only browser but it requires safari app to be allowed from the content blocker in screeen time app. If I disable the Safari from that app Violoncello gives error and doesn't load pages. My reason to have a only text browser and disable safari is that this safari app has a bug which enables user to access undesirable websites despite restrictions.

so I want to create a text-only browser IPA for my personal use that works with safari disabled either by apple configurator or screen time app .

I am not an app developer but generally aware individual who would understand if guided step by step broadly.
