Overview

Mabel sells microdosing mushrooms. Everyone who buys them gets access to a companion app: a private space with guided meditation classes, audio chapters and a personal journal to accompany them through the program.

Problem

Microdosing is a personal, often introspective experience, and people had no structured way to follow a program, reflect on what they were feeling, or notice how their mood was changing over time.

The app needed to guide them gently, day by day, and offer insight into their emotional state without ever making that writing feel exposed.

Process

I started by mapping the whole app in a user flow: first-time onboarding with a baseline survey, a home screen that tracks progress through the 30-day program, classes split into meditations and chapters, a timestamped journal, and settings. The flow also marked what belonged to the MVP and what was reserved for premium users.

The journal is the heart of the app. Users write or dictate how they feel, and AI reads each entry to detect their mood: joy, anger, fear, disgust, sadness or calm. The result is shown only to them, as a small tag on each entry, so they can see patterns and get guidance without anyone else reading their thoughts.

Journal

Journal list with entries grouped by chapter, each tagged with a detected mood such as Calm, Joy or Sadness Open journal entry showing the full reflection, the date, the chapter it was written in and a Calm mood tag New journal entry sheet asking How do you feel, with a microphone button for voice journaling

The program is built from chapters that unlock in order, each one with audio narration and a reflection to complete before moving on. Guided meditations sit alongside them as a library people can return to anytime.

Home and classes

Onboarding stays short: an account, then a 14-question baseline survey that gives the program, and the user, a starting point to compare against at the end.

Onboarding and settings

Outcome

I delivered the complete UI for the MVP: onboarding and the baseline survey, the 30-day program with chapters and guided meditations, and the AI-powered journal. The user flow gave a clear split between what belongs in the first release and what is reserved for premium users, so the product has a defined scope ready for development.

Some ideas were intentionally left for later, such as an emotion visualisation: a colour-coded view of how someone's mood changes across the program.
