Process, Research Design

  1. Ethnographic research about how mobile devices are used in public.
  2. Pitch an app idea that is interesting and has a viable market
  3. Draw Comics of users interacting with the app in various scenarios
  4. Survey and Cultural Probe research about our app idea
  5. Develop prototype personas and conduct a competitive analysis
  6. Create 3-4 initial designs (drawings, sketches)
  7. In class user testing
  8. Select 2 designs to develop further for testing (digital mockups)
  9. Moderated user testing (in person interviews)
  10. Select one design for further testing using an “animated” paper prototype
  11. Moderated user testing (in person interviews)
  12. Iterate on the design and create a working Axure prototype
  13. Moderated user testing (in person interviews)
  14. Storyboard for a pitch video

Key Findings

There are many period tracking apps out there. They all glamorize “that time of the month” with user interfaces involving bubbles, flowers, and lots of pink. Unfortunately, most women do not delight in “Aunt Flo’s” monthly visit.

Only 25% of survey respondents took note (mentally, physically, or digitally) of when she will be ovulating. Yet, every respondent reported at least one menstrual/PMS symptom within the last 90 days.71% of the 48 survey respondents are using some sort of tracker app. 84% of respondents who use a tracker app are able to log data in less than one minute. We decided to move forward with the idea and focus on biological females who are not trying to conceive.

One surprising benefit of using a cultural probe was the sheer range of responses it encouraged. It paired very well with the strict, easily quantifiable results of the survey. No two people chose the same three symptoms, and the symptoms weren’t straight off the Wikipedia page for “menstruation”.

Visual communication and cues are needed alongside text labels. People were more confident in making a selection when they were quickly able to confirm their assumptions with multiple cues.
