Saent offers a solution for those of us who are incapable of either closing the tab with Facebook or our email in it, or of ignoring any notifications that appear in those tabs. It uses the Pomodoro Technique, which is a time management theory that says your ideal working to break time is 25 minutes on, 5 minutes off, to be more productive while still not getting bored and/or spacing out. After 25 minutes or so, those shiny things get more tempting, as I can attest.
See that big white button in the picture above? That's Saent. It connects with your computer via bluetooth, and when you hit the button it basically acts like hitting mute on your speakers: Any apps you decide shouldn't bother you while you're working will be blocked until such time as you decide they can intrude again. It's fully programmable, and can be taught to recognize when an important email (say, one from your boss) should get through even though you're blocking emails.
There's more to Saent, of course, but those are the essentials. Saent is currently seeking funding on Indiegogo, where a pledge of $75.00 US will get you a two-pack. They're not quite to their funding goal yet, but there are about three weeks left in the campaign. Estimated time of delivery is this coming November.
