Treelet Diary: Mood Journal

Treelet Diary is a privacy-focused journal app that maps your mood alongside sleep, heart rate, activity and mindfulness data from Apple Health on a single timeline. It supports voice notes, on-device AI reflective feedback and weekly reviews, helping you see connections between your bodily rhythms and emotions — the app does not provide medical diagnosis or treatment advice.

Core Features:
• Mood Overview: Aligns your daily mood with health snapshots for easier understanding of the relationship between physical state and present feelings.
• Voice Journal: Converts speech to text for journal entries, with auxiliary atmosphere and energy sensing (results vary by environment and expression).
• Health Context: Integrates sleep, activity, mindfulness and other data to cut down manual entry and make your journal more reflective of your real day.
• AI Reflective Feedback: Generates empathetic summaries and perspective prompts locally using on-device models (works on supported devices without mandatory internet access).
• Weekly Reports & Growth Page: Weekly pattern summaries and simple comparisons to help you track changing trends.
• Privacy & Security: Includes app lock and list blurring features; psychological content is treated as sensitive by default. Health and journal data are stored primarily on your device, see in-app details for more information.

What you get:
Mood overview timeline (mood × sleep × heart rate on one axis), psychological review weekly reports (mood distribution / anxiety word frequency / average sleep metrics), voice journal (on-device transcription + ambient sound atmosphere tags)

Who it is for:
Users who want to organize their emotions through journaling while incorporating steps, sleep, heart rate and mindfulness data; users who value privacy and wish to reduce concerns about content being uploaded to the cloud.
Beginner-friendly for busy users: people who dislike typing or lack time for reviews can still maintain consistent journaling.
