Pay Nothing for the Lockr for iOS (originally $0.99)

Get extra security through the Lockr deal on itunes. This note storage app used to be $0.99 but is now free. Lockr protects your notes from unwanted eyes using pattern-lock, pin, or password. Security with the password can be done with symbols, numbers and letters to create a strong combination. You can only use numbers when opting for the pin feature. The pattern-lock feature allows you to use 4x4 or 3x3 column-row combinations to ensure proper security. Set your own preferences as far as how big or small you want the font, the style you want to read it in, and the color-theme. You get AES-256 bit encryption to secure your documents. The key to the encryption is stored remotely.
