Think about your activities and roughly categorise them into productive activities, procrastinating activities and neutral activities. Whenever you are doing something productive, press '+' to earn time. Whenever you are procrastinating, press '-' to spend your hard-earned time on leisure activities. Press '=' when you are doing something you have categorised as neutral. In the settings you can adjust the relative value of productive time compared to procrastination time. For example, you could set the timer so that 3 hours of productive work only earns you 1 hour of procrastination fun time. In my experience, it works best to only track the time you can control. So if you have to work 8 hours a day just set the timer to neutral during your working hours. Also when you first start out I would suggest setting the ratio of productive time to procrastination time to something comfortable. One productive hour for one procrastination hour is a good place to start when you consider all the time you have available. Once you feel comfortable with this schedule you can slowly increase the amount of procrastination time.
After opening timeth.at for the first time in a browser all required data will be cached locally. This means that timeth.at should work without an internet connection after loading it the first time. It's also possible to close the website while the timer is running and reopen it later without internet connection and the website will show the updated timer. timeth.at is also an installable web app, so if your browser supports installing web apps you'll get a home screen icon for timeth.at and a native app like experience. timeth.at does not send any tracking or telemetry data. Note that there is no way to synchronise the timer between computers or even between different browser instances on the same computer, and if you clear all data stored for timeth.at in your browser, you will lose the current time value.
