油價 is a utility app available on iPhone that focuses on providing real-time oil price announcements for Taiwan CPC and Formosa Petrochemical Corporation. Users can easily reference retail prices with the app. The app supports both Dark Mode and Light Mode for user preference. Additionally, 油價 offers three widget sizes for convenient use: 2x2 to display a single oil price on the desktop, 2x4 to show complete price information for either CPC or Formosa, and 4x4 to display both suppliers' prices and price change details from the previous week. Users can even add the 油價 widget to the iOS search bar for quick access to oil price information without unlocking the phone.
