Ive used this app for 3 years and I love it. Ive been able to track my mood, monthly and seasonally which has provided me with great insight into what influences changes in my mind/mood state. I also am able to track the physical pain I experience. When I dont have words to express my mood I take a photo and save either a selfie or a photo of my surroundings. I would recommend this to anyone looking to track their mood.
