Key features include: • Mood tracking with single-tap input • Customizable reminders for medication and appointments • Integrated calendar for managing schedules and companions • Private journal and reflection prompts • Granular control over shared information with companions • Supportive, non-clinical dialogue for late-night thoughts This application is designed to bring structure and support to the often challenging periods between medical appointments.

The unique privacy controls enable users to decide exactly which pieces of their experience—from mood summaries to journal entries or financial costs—are visible to trusted companions, ensuring personal data remains private unless explicitly shared. Companions receive updates discreetly without knowing what has been withheld. Cairn is engineered to be a reliable presence during tough times, offering a listening ear without crossing clinical boundaries.
