If you're like me and don't like to use a password for unlocking your BlackBerry 10 device you may well be interested in Secure Notes which is free to download form BlackBerry World. 

We've seen our fair share of note applications on BB10 but Secure Notes, although basic and simple, offers some added security. Once you launch the app for the first time you will need to generate a password. After that, each time you open the app you will need to enter that password to actually gain access to the application. 

Then it's just a case of pressing the + icon at the base of the display to create a new note. Once saved your notes will be listed in alphabetical order and you can quickly edit or delete them. 

And that's pretty much it. The app has the typical BlackBerry 10 style user interface and although quite limited in terms of functions it does give you piece of mind that if your BlackBerry gets into the wrong hands they at least won't be able to access your notes.
