What is TeddyNotes?

TeddyNotes is a personal journaling app built for emotional reflection. Write one note a day, tag your mood, and let Teddy — your AI bear companion — check in on you like a close friend would.

Features

• Daily Journaling — One note per day with mood tagging. Past notes are sealed and read-only.
• Mood Activity — Notes are color-coded by mood across a scrollable list.
• Teddy AI Chat — Context-aware AI companion powered by Gemini. Teddy reads your last 4 journal entries and responds like a friend, not a therapist.
• Mood Insights — See your most frequent mood this week on your profile.
• User Onboarding — One-time setup for name, DOB, email, gender stored locally via DataStore.
• Edit Profile — Update your details and profile photo anytime.
• Search Notes — Filter your journal entries by title.
• Offline First — All notes stored locally using Room DB. No account needed, no cloud sync.

Setup

This app uses Firebase AI — you'll need your own Firebase project to run it.

1. Create a Firebase project at console.firebase.google.com
2. Add Android app with package name com.example.teddynotes
3. Download google-services.json → place in /app folder
4. Enable Gemini Developer API in Firebase console → AI Logic
5. Build and run

Or download the latest APK from RELEASE to try it directly.

Design

• Palette: warm bear browns, paper beige, muted greens
• Fonts: Lobster Two (display), Nunito (body)
• Cozy, calming aesthetic — not a productivity tool

---

What I learned building this

• Jetpack Compose UI from scratch
• Room DB with TypeConverters for custom types
• DataStore for lightweight user preferences
• Prompt engineering for context-aware AI responses (RAG-lite pattern)
• MVVM architecture with StateFlow and coroutines
• Navigation Compose with typed routes
