Uppernote is an easy accessible note that not only keeps your notes or agendas; it also saves them into a specific date. This makes this app great for note taking and keeping track of your plans.
The idea is that you can post the note as a sticky on the desktop, or save it as a text file. Also have that note scheduled and saved to have it posted on a specific date. Basically, it will automatically appear, as a sticky, on your desktop to remind you of that day’s plan.

So Uppernote is:
1. Easy to use
2. Easy access
3. Will not interrupt your work
4. Posts important messages
5. Schedule when to post important messages
