PackPal is an intelligent iOS app that helps travelers pack smarter, faster, and stress-free. Using on-device AI, it generates personalized packing lists based on trip details, activities, and weather, all while keeping your data private.

• AI-Powered Packing Lists: Personalized based on trip duration, destination, and activities.
• Smart Context Awareness: Automatically adjusts for weather and conditions.
• On-Device Privacy: Built with Core ML to keep all data local.
• Natural Language Input: Type phrases like "4-day ski trip in Alberta" and PackPal knows what to include.
• Modern Design: Clean, intuitive UIKit interface with consistent color themes.

PackPal follows an MVC architecture with a modular service layer for AI and data handling. UIKit manages all interface components, while Core ML powers the AI logic for generating packing recommendations. The design system maintains consistent color, layout, and typography across the app.

• macOS with Xcode 15 or later
• iOS 17+ simulator or physical device

1. Clone the repository:

   git clone https://github.com/Somebody239/PackPal.git
   cd PackPal

2. Download the AI model:

   ./download_model.sh

   or manually download from Apple Core ML Models, rename it MobileBERT.mlmodel, and place it in PackPal3/AI/.

3. Add your API keys:

   • In AI/HuggingFaceService.swift: Replace "YOUR_HUGGING_FACE_API_TOKEN_HERE".
   • In Utilities/WeatherService.swift: Replace "YOUR_OPENWEATHER_API_KEY_HERE".
   • Get a free key from OpenWeather.

4. Open the project in Xcode:

   open PackPal3.xcodeproj

5. Build and run on a simulator or device with ⌘ + R.

PackPal was inspired by the stress of last-minute travel packing. That "Did I forget something?" feeling can ruin the start of a trip. PackPal was built to make sure travelers can leave with peace of mind, every time.

PackPal helps travelers pack efficiently and avoid forgetting essentials, reducing overpacking and waste. By encouraging smarter travel habits, it supports more sustainable and organized travel experiences.
