Hi!
First of all - Thank You for sharing your work with us! Much appreciated!
Now, this is not specifically related to this app, it's related to almost every note app out there and a bone I have to pick with them :P
- Most of these apps are presented in a "remind me to do" style manner. "Buy flowers!" for instance. Now, this is perfectly fine to put in a note, but, the problem with this is that I, for instance, personally am going to forget to buy those flowers anyway.

Why? Because I would have to be reminded to open the Note app and read the damn note
Solution: on my former nokia symbian based phones there was at least one line on the homescreen that contained notes/reminders so whenever I look at my phone I actually get reminded. My suggestion to all Note app makers is the same: make notes that can (if we choose) remind us, via sound, popup, alarm, anything really, it just needs to be visible as soon as we look at the phone (turn the screen on or at least unlock the phone and enter homescreen). For instance, Notif (app on playstore) does this by utilizing JellyBean's advanced notification pull down system and making persistent notes in there (of chosen). There are also some widgets (MemoWidget for instance) that allow you to type in them. Placed on a homescreen it's a pretty good reminder.
I personally tend to utilize in-build alarm app for "buy flowers" that way there is no way I can miss it. Sometimes even calendar events with alarm function are good choice but personally I find the calendar app too clogged and complicated to use for simple tasks/notes/reminders.
Now, I like this simple nifty app that you made, it's very clean and simple to use. All it needs is some kind of reminder to at least remind you to open the app and read the note!

That's my opinion anyway, it's not a demand, it's just wishful thinking!
