I built a one-tap "don't bother me" mode for my phone, and it solved a surprisingly big problem

My phone plays many roles. It's a source of entertainment, a useful tool for work, a way to communicate with people, and more. These different uses don't always play nicely together. When I'm working, I don't want to be distracted by unnecessary calls, messages, and notifications, so I built a one-tap system to stop my phone from stealing my attention.
