We are a little reluctant to take on the responsibility of managing and keeping of numerous personally owned expensive devices, but we support students effort at productivity. If you have a documented disability that affects your ability to focus, please visit the awesome staff at Accessibility Services. If you just have a hard time disconnecting from your device, consider an app to aid in non-distraction or that helps you limit your cell phone checking. Try searching "pomodoro" or "forest" in the app store of your choice.
