The Sad Scale app from Deep Pockets assesses your emotional state, even if you think you are already aware of it. Created by a physician, answer a series of 20 Zung standardized questions that will be scored and you will be told where you stand on a Depression, Geriatric or Post Partum Scale. While this is not a substitute for real therapy, it will save the last 30 entries that can be e-d to your doctor. The iPhone and iPod touch application is available at the App Store for $.99.
