Partner sharing was a feature already offered by our some of our competition. They usually offered a 'boyfriend mode', a single purpose screen to view a partner's cycle.
Our competitors conducted several public polls on social media. According to them, the majority of people were only interested in sharing their cycle with their partner. Due to this, the scope of our project was initially set to build a partner sharing feature.
I started out by creating an email list of interested users by filtering the support database for everyone who previously messaged support about this feature. I also used the company's social media accounts to spread the word.
Having access to a list of around 90 interested users allowed us to filter leads using a screener, ensuring I would schedule user interviews with a diverse set of users. Staying in touch with users who requested this feature made the community feel engaged. It also allowed me to later conduct further quantitative research through surveys.
After around ten user interviews it became clear that users were actually quite interested in sharing their cycle with more people than just partners. People expressed diverse needs, ranging from teenage daughters wanting to share their cycle with their mother to people asking to share their cycle with close friends.
One example stood out to me specifically, a 12 year old girl. She and her friends were all using Clue to track their menstrual cycles and already did a regular sit-down where they would share their experiences of what was going on with their bodies.
This made me question our initial plan of creating a partner sharing feature. I decided to send out a more detailed survey where people could choose from a variety of sharing options they would be interested in. The results showed, that when asked in a more detailed manner, a majority of people were in fact interested in sharing their cycle with people other than their partner.
Because of this we decided to instead scope the project to a more general version of cycle sharing. This also presented a powerful growth opportunity for the company: we could use cycle sharing as a way to access a network effect.
