Spot On is a birth control and period tracker powered by
Planned Parenthood with a fun, simple interface that
allows users to quickly record their period, symptoms,
moods, and activities. By using the app consistently,
users can begin to understand better what affects their
menstrual cycles, and how their cycles affects their
bodies. Spot On helps users stay consistent with their
birth control with gentle reminders and provides
guidance, tips, and information about reproductive
health — whether they're using the pill, patch, ring,
implant, shot, or IUD. For those who aren’t using birth
control, Spot On provides period predictions that become
more accurate over time. More at
