VisionKit Image Analysis

Analyze VisionKit analysis requests on images.

Overview

The data in this report shows histograms for the quantity of information found when performing a VisionKit analysis request on an image. The information includes the length of text, the number of visual lookup elements, and the time to parse the machine-readable codes in the image.

  • Territories: Worldwide

  • Platforms: iOS, iPadOS. For more information about iOS and iPadOS, see the Platforms section in Data Completeness and Corrections.

  • Availability:

    • Daily: Every day.

  • History: On request, data is available beginning with iOS 17.4 and iPadOS 17.4.

  • Completeness: Data from devices that contribute to this report can arrive as late as 8 days after the date it generates on device. You can download recent data daily, but it might be incomplete, and data updates incrementally daily, until all late-arriving events are available.

  • Privacy:

    • Includes data from users who have opted to share their data with Apple and developers.

    • Individual rows will only appear if they have a value of 5 or more.

  • Data Context: You can analyze your data with additional context by comparing it with the data in the App Sessions Context report, which provides a count of unique devices that use your app on a specific day. For example, if your app performed an action detailed in this report on 10 unique devices on a specific day, and the App Sessions Context report shows there were 100 unique devices running your app that day, then you can approximate that 10% of the devices running your app performed that action.
