Thank you for super useful comment!
I was not aware of the concept of gradient dead zones. Will investigate.
As for the gradient color, I am a little bit married to it since the app implements very similar one. I wanted to keep the theme somewhat consistent between app and website. I assume you are referring to the website since you also mentioned drop shadows. I actually used gradient tool https://cssgradient.io/ at least for the app.
Still, I will definitely check the font and color for the website. Thanks!
