This is the best app for tracking almost anything. It is more sophisticated than most, meaning that you have to understand the "Categories" and "Items" relationships. I personally use it to track Health - nausea, fatigue, and stress, Food: Breakfast, lunch, dinner, snacks, water, and coffee/tea, Pain - headache, back, neck and shoulders, abdominal, intestinal, and foot, BM and Urine output.
My suggestions for the manufacture are to provide easier sequencing of categories and items within categories. Also, a larger library of images for items. I bought the IBS companion app and found that T&S would do everything I needed acceot the images.
Well worth the purchase for the main app, and worth the time to practice using it to get to know the elegance of the user interface.
