In the app description: "Not another cute, pink app. drip. is designed with gender inclusivity in mind"
So it's a perfectly conscious choice, and that's exactly what turns off some women who might prefer a cute, pink app. I have nothing against inclusivity, quite the opposite, but in this case they could offer two themes rather than imposing an app that isn't "cute". Even as a man, you can prefer cute things.
Okay, that's strange. It also doesn't make sense to me. Making an app non-pink and not-cute doesn't seem gender inclusive at all to me. It's a perfectly fine design choice on its own, but implying that non-pink things are somehow more gender inclusive than pink things is quite stereotypical about traditional gender roles.
