Everyone has some important information that must remain private at any cost. Sometimes, this can take the form of important information such as phone numbers, addresses, or even a short note from that meeting you just left, and you must protect this data from prying eyes. Due to their size, accessibility, and reliability, Android devices make for great private notebooks.
There are many applications offering taking and storing notes. Some of them also add widgets, but not many give you the ability to password protecting your notes. One such applications is IO Notes by XDA Forum Member djonnystevensabenz. This app is a simple, minimalist tool that is able to store notes in an encrypted database that requires a password to unlock. The unlock key must be at least 8 characters long, so it won’t be very easy to crack on the device itself.
In addition to its privacy features, IO Notes has a great interface. For example if you find yourself distracted easily, you can use IO Notes in Zen Mode to dim the status bar and minimize the surrounding “noise” of notifications. The app also features two graphical styles, light and dark, so you can customize it to fit nicely with your favorite ROM. More functionality is already planned, and will be ready to use in upcoming releases.
