I liked how it tracks what apps or websites you are on. Even Emails Help's you to keep focused

It's so easy, you don't have to do anything. Just work and it will track your activity. It is 0 annoying, as they only notify you of really relevant events.

Absolutely easy to automate tracking 100%. Just configure it once and forget about it. RescueTime can track the titles of the documents in every app (if you choose to enable it) -- so much so, that you can ignore a particular Twitter page, but mark another as productive, and another as distracting. I went Pro several years ago, and continue to use it every day. Gives me the surest way to benchmark my productivity. Automatic triggers can help you save time from distractions (e.g. shut down social media for an hour, after spending more than 10 mins). Daily goals are also nice (Get x hours of writing done, not more than y hours on emails, etc.). RescueTime has way more features, and use cases than I describe here. So do check it out!
