StayFocusd (Chrome Addon)
This is an addon on your internet browser to limit access to websites that you do not want to spend your time on. For example, you can limit your access to social web for 30 minutes and after you reach the limit you need to wait another day. The nice thing is that program does not allow you the change the settings in any way about limits in the same day after you reach the limit. This addon on Chrome has been helpful for me to make more of my time on the internet. It is a very well thought, feature rich and constantly developing application.
Blue Coat K9 Web Protection (Desktop Application)
BlueCoat is basically a parental control application but for me, it works very well for two other reasons rather parental control.
First you can set up times for to automatically block all the internet. If you are having problems about shutting the pc down when it gets late that you are supposed to sleep, this program is for you. If prevents all the internet connection in all browsers in a time that you set. And it does shut down the pc automatically, just prevent the internet connection thus if you have an unsaved work, you can first save it.
Second way I benefit is that it can block some specific websites in all your browsers. StayFocusd is working only on Chrome but Blue Coat works in all browsers. So as an example, you can limit your access to Facebook on StayFocusd and you can block your access completely to some timewasting websites that you are addicted on Blue Coat.
The main downside of the program could be that all the control is based on a password. If you know the password, it may be tempting for you to log in and cancel the blocking. So I suggest you to have your friend or family to set up the password.
ColorNote (Android Application)
Whether on a paper agenda or on your mobile phone or in another way, note taking is a must. This is a mobile application for android phone owners. If you like to take notes on your android phone, I would suggest ColorNote. It is an offline application, so you do not need internet to take notes. You can take your notes in the form of text or checklist. You can color some notes and set reminders at a time or recurring. And you can set snychronisation so you never lose your notes.
