This is not a comment about the content (I have a digital subscription with the FT - the articles are very good). But the app is really bad. It is basically the website in their own browser. Just worse.
The navigation is a nightmare. Finding sections is everything but intuitive. Then, because it is a website, they use an enormous amount of trackers and other stuff I don’t like. You cannot easily switch font(size), background colour, etc. They offer a „night mode“ in experimental settings, that’s it. But the worst is all the ads breaking up the text. Not like in other newspaper apps where you get a page you just swipe away.
Basically, I avoid the app and open the website in safari to use its reading mode. If your (bad) website beats your app, you failed your job.
