Bests & Worsts Reviews from Amazon

I recently downloaded this (free) app for my Kindle Fire after reading all of the reviews. I love the features of: The lock - being able to keep some of my thoughts private *press the menu Icon @ the bottom of the screen once you have the app open & press the "back" arrow to lock the app when you walk away *the ability to reset your password while the app is open The background - being able to change the color so it is soothing for me
