Show HN: An Intelligent Planner That Adapts to How You Work

I have FINALLY learned how to manage time. I know procrastination is still a huge problem at my school. Every morning I can still find people just coming home from pulling all nighters. I'm working to compile best known solutions into a smart planner. Other solutions focus more on showing what to do that helping you get stuff done. Here's what it does:

Helps yoy break your work down into smaller pieces (30minutes -> 1.5hrs, our attention spans are short)

Helps you estimate how long work will take (based on your past personal history)

Adapts to your working habits ("John really gets a lot of work done at 11pm on Sundays, let's ask him to schedule a short task then to save him time later")

Show you how much free time you have and how you can get more

Help you eliminate distractions

Syncs with Google Calendar, Evernote and Dropbox (Coming later)

…and more
