Uppernote is an easily accessible note-taking app that not only keeps your notes or agendas, but also saves them into a specific date. This makes it 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.
