TabZolo (Chrome extension): allows you to focus on only one Google Chrome tab, while temporarily hibernating every other open tab. Set the timer for 15 minutes or 2 hours or indefinitely, and when the timer runs out, your phone goes back to its default sound settings. Shush (Android): does the same thing for your Android phone. This one's great for quieting your machine when presenting a deck at a meeting or for silencing the Mac for 30-minute work sprints. Hush (Mac): temporarily silences your Mac’s system alerts so you can work without getting distracted by popup windows or chiming notifications.
