Disappointing that this collects all kinds of data, but only seems to use one source of information to predict patterns. It's also disappointing to me that for all the symptoms data I collect, I cannot view it in a chart over the span of the month. Period symptoms all times of the month should be used to calculate cycle, not just period start date. This app is very weak unfortunately for period predictions. Could also be more customizable for users to add their own input.
