Variability in tracked daily flow volume for each level of reported bleeding heaviness. Each of the five panels is specific to a reported period heaviness: very light, light, moderate; heavy, very heavy (n = number reporting a specific heaviness). Each histogram within a panel is specific to light, medium, or heavy app-tracked days; x-axis (for each histogram in each panel): for each user, number of app-tracked days that had been tracked as light (histogram 1, pale pink), tracked as medium (histogram 2, pink), or tracked as heavy (histogram 3, red); y-axis (for each histogram): % of users in each reported heaviness category; see main text for additional details and an example of interpreting the plotted data
