  1. Hi Jan,

    As you know I already started development on a similar app. I would like to share some of the features I had in mind for that app:

    1. Apart from recording bytes per category, the app would record bytes per content type (e.g. video, audio, picture, text, torrent),bytes per language of the page (this I can explain later), and also length of internet activity.
    2. You could get a report of those things in nice graphs.
    3. Goals were more complex, not just 'shun this category'. Instead, I used the concept of 'badges' like Stackoverflow and goals were shun/strive for a badge. Example badges are (you can think of more fancy names yourself) '1 week offline', 'pornography', 'less than 1 hour audio per day', 'more than 2 buddies'. (Technically this is a little complex: you have to use combinations of conditions, where a condition is of the format 'attribute < value' and attributes can be:
      1. bytes per category X
      2. bytes per content type Y
      3. bytes per language Z
      4. activity percentage per day
      5. total number of bytes per day
      6. number of days offline at a stretch
      7. number of buddies
      A user/buddy will receive badge updates like 'you earned this badge' or 'you lost this badge'.
    4. I also had in mind that if a user prefers this, she can still use blocking from the app to be able to reach her goals. You could say "I want to get this badge" and then set a checkbox 'block pages that will give me this badge'.

    These features are maybe suggestions for Yona too, although it will increase the complexity of the app...
