>iPhones do not offer different colors. I don't mean you chose colors and corner radius because you want to make your buttons look like candy. I mean features like text sizes and high contrast , go check your iPhone Accessibility section (but only if too many settings won't affect negatively, there are probably many options and labels to read). My point is that hard-coding fonts,sizes and colors in your app is against accessibility, some fonts are harder to read then others for some people, small sizes is obvious the issue, some people need higher contrast then gray on white to read comfortably. If you are a competent dev or designer you need to understand that your app needs to work if the user wants a different font and different colors, Apple has guidelines. What would be nice is to think about the app as a tool that lets the user do a job and not like a work of art that a desgner needs to add it to a CV,
