Overview

Relief's Map is an iOS application designed primarily for users in Korea, focused on detecting hidden cameras to enhance personal privacy and safety. It offers multiple detection methods including AI-powered visual scanning (TensorFlow Lite), magnetic field detection (using the device's magnetometer via Core Motion), and infrared light detection. Users can also view a map (Google Maps) displaying locations with user-submitted safety reviews (posts), ratings, and images, contributing to a community-driven safety network. The app includes user accounts, authentication (Kakao, Google, Apple), and a subscription model (SwiftyStoreKit) for accessing premium features like the 'Pro' AI detection mode and removing ads.

Key Goals:

  • Provide users with accessible tools to detect potential hidden cameras in various environments.
  • Build a community-driven map of safe/unsafe locations based on user reports and ratings.
  • Offer both free and premium (subscription-based) detection features.
  • Ensure user privacy and data security.
  • Deliver a user-friendly and intuitive interface.
