Why it is so ugly

I always wonder why some developers completely destroy the usability and design aplication by ugly design - why do you not go with standard apple design rules, colors, fonts, settings in settings panel etc., if you would just simply copy the default apple phone app design, plus add SIP as (optional/prefered) way to call, everyone would thank you and buy this application. PLEASE!
