I believe the title of this post is accurate.
Every one of us, in order to read this post, needed to use some sort of web browser to render and load in applicable content. Some used the integrated browser connected by Instagram, others manually searched up zachsthoughts.com/mrt to be brought here via their main setup.
Or you could be one of the lucky few that has the dedicated iOS web client, which in of itself is merely just a fancy locked-down bookmark from Safari. But the point still remains. The browser, if anything, is the one app that we all use at the very least daily. Even if you try to hide it.
Don't bother, because it'll show.
