• iPhones older than iPhone 4 are not as powerful as Apple’s latest devices. Storm Shield may be slow to run on outdated versions of iOS. The app will run better on newer devices with Apple’s current iOS installed. We strongly suggest you upgrade your device’s iOS to the latest version.
  • The initial load and display may also appear to be slow because Storm Shield is loading a radar image - which may take 20 seconds or more depending on zoom-settings and network conditions.
