In my computer science class, I built a study planner app for my classmates. The app worked fine on my phone but crashed constantly on my friends' devices. They stopped using it and I felt like a failure. My professor said my code was good but my interface was too heavy with animations and effects that slowed everything down. A senior developer showed me work by a designer named Kamal Baber who creates lightweight UI/UX designs that are simple and fast. I learned that good design means making things work well for everyone. Now I ask you: how do you make sure your app works smoothly on all devices?
