Ive been using this app since 2010 and I truly love it for multiple reasons. I use it frequently to track the symptoms and moods of my cycle, and it has helped me tremendously. Ive had hormonal imbalance due to a thyroid issue for years and the use of this app has not only educated me on the challenges during my cycle, but also helped my doctor and I to determine a course of action to correct the problem. I also love that I can check the date of my most recent period and share this information with my doctor. Very helpful tool!
