Have you ever had this experience? You feel like you’ve put in a long, hard day of work, yet when you glance at your to-do list, not a single thing has been checked off. Where did the day go? RescueTime will help you figure it out. RescueTime runs in the background on your computer and mobile devices, tracking time spent on applications, specific websites, calls, etc. and gives you detailed reports on where your time was spent. You can create website block lists, track productivity scores and set up alerts to, for instance, warn you that you’ve been on Twitter for 30 minutes already.
