Frequently Asked Questions​—JW Library (iOS)

JW Library is compatible with devices that run one of the following operating systems:

  • Android 4.1 or later

  • iOS 9 or later

In order to keep JW Library secure and reliable, we cannot continue to support all older operating systems and devices. Occasionally, we need to raise the minimum requirements to run the app. Therefore, we recommend that you update your device to the latest version of its operating system.
