> Phones are bigger than ever

If you want to experience what your app is really like for the vast majority of real world people, go get a cheap monthly prepaid phone and try it out. Using the modern web on them is a complete nightmare. The screens are physically small and low resolution. The phone I had to use for a year and a half is 800something by 500something, which is literally first generation Android era resolution from over ten years ago. Information density matters. Huge buttons that get in the way are not merely frustrating, they are a design mistake and a demonstration that the designer is out of touch with reality, just as you seem to be here.

Please, get a crappy phone, get a crappy chromebook, make sure your app isn't frustrating to use for people that can't afford new, fast things.
