Tetragram is a medical cannabis journaling app that helps patients track strains, symptoms, and what works for them. Existing tools didn't make the tracking process feel simple or approachable — and a single session log involves a lot of input for someone who might be logging while managing pain or anxiety.
We worked closely with Tetragram's CEO and founder, who is a medical cannabis patient himself. He shared direct insights about users' goals, which gave us a strong foundation. I knew it had to be a friendly, welcoming, and empathetic experience — something that I could picture him using himself. Later during our project process, he shared he would be using this app for his own personal use tracking. The team aligned quickly on making this a people-first interface. The journal-first approach was guided by the goal for users to feel a personal connection to the app — making the experience user-first and personalized lets them keep their own experience journal-only, if needed, with accessible ways to more broadly connect through the Community and Dispensary tabs.
The logging flow is a progressive sequence where each screen asks one type of question. The Health Goals screen uses chip selectors because they show all options at once rather than hiding them behind a dropdown. The Product Info screen organizes dense data (cannabinoid percentages, terpenes) in a clear hierarchy with consumption method icons that turn a text-heavy selection into a quick visual scan.
The community feature evolved during the design process, with the founder wanting a group-focused experience. I kept it accessible from the bottom navigation but out of the journaling flow, so it adds value without getting in the way of the core experience.
