ReCall Study Time is a Chrome extension that is designed to help you stop wasting time on social media sites and get back on task. With the extension installed and enabled you'll see a big reminder to get back on task whenever you try to open Facebook, Twitter, YouTube, Google+, or Instagram in a new browser tab. You can ReCall Study Time to block you from those sites for two hours or for 24 hours.
Applications for Education
ReCall Study Time could help some students stay on task when they're studying or working on homework. Of course, it is easy enough to disable the extension so ReCall Study Time provides suggestions rather than truly blocking social media sites.
Stay Focusd is a similar Chrome extension. Stay Focusd works by setting daily time limits for viewing social media sites.
