Bad design is frustrating. Bad app design is infuriating (if you see as many apps each day as I do, anyway - send help).
Designing the aesthetic presentation and user experience of an app is no small task. Seemingly simple design choices have enormous impact on what ends up in the hands of your users.
Will the hamburger menu drop down from the top or should it be swipable from the left? What kind of transitions should you use between sections? What icon is best for the Settings tab? What precise color palette communicates the right message for your unique snowflake of an app? And so one and so forth.
Pro UI/UX designer Liam Spradlin deals with these kind of critical decisions constantly, resulting in some of the most popular and intuitively designed apps on the market today (Focus, Nova Launcher, Allcast, Today Calendar, and more). We scored an interview with him, picking his brains on gathering and acting on user feedback, redesigning apps that are already popular, and designing mobile tools that feature a persistent sense of "fun."
