I used the traditional cycle beads for 5 years with the only visual being charts and dates I created in Excel. The app is a superior visual tool that is much more user friendly than remembering to physically move the band on your beads.. Not to mention the graphic displays on the calendar. Great job. Perfect for women who are regular (see medical description) and are family planning whether its to prevent or aim for pregnancy. Also for those looking to not take hormones and be as natural and in tune with your body as possible. Great job cycle beads.
