Every time a web app sends a notification, it isn't just an alert—it's a context switch. Studies show it can take over 20 minutes to return to deep focus after a minor interruption. When your browser is a source of constant pings from Slack, Gmail, WhatsApp, and project tools, you aren't working; you’re reacting. The problem with standard browsers is that notifications are scattered. They pop up over your work, disappear into a hidden system tray, or hide behind a tab you can’t find. This leads to "notification fatigue"—the feeling of being constantly overwhelmed by digital noise.
