Introduction to Mobile Recorder in Katalon Studio

Mobile Recorder

To start recording a mobile test, click on the Mobile Recorder icon on the main toolbar, and select your device type. Katalon Studio supports local Android or iOS/Remote/Kobiton mobile devices.

The Mobile Recorder dialog with multiple components appears for your recording sessions.

Action Bar

Action Bar located on the top left corner contains the Capture Object, Start, and Stop buttons.

  • Capture Object: When you click this button, Katalon Studio captures all mobile elements displayed on the current screen of the device.
  • Start: Click on this button to start recording, Katalon will deploy and open the application on the configured device. This button is enabled after you specify the AUT.
  • Stop: Click on this button to pause recording.


The Configurations area is where you choose a mobile device and application under test (AUT) for the recording session.

  • Device Name: A mobile device where Katalon launches the application (All of your connected devices should be displayed in this list.)
  • Start with: In the drop-down list, you can select either Application File or Application ID
    • Application File: Browse your tested application (.apk file for Android; .ipa file for iOS)
    • Application ID: Specify the application ID of your tested application, which is either the package name of an Android app or the bundle identifier of an iOS app.

Device View and All Objects

To select an object, you can click on any object either in the tree of All Objects or in Device View. Katalon highlights their counterpart accordingly for verification.

  • Device View is a simulator of the device screen. You can interact with the AUT in this view.
  • All Objects captures and organizes all the displayed mobile objects of Device View in a tree.

To make sure the Device View displays the current screen of the AUT on the device, you can click on the Capture Object button to reload Device View and refresh All Objects.

Captured Objects

Captured Objects display all objects that you have interacted during the recording session. For each object captured by Katalon, you can find its detailed properties shown in the Object Properties table by double-clicking on it.

The most important property of an object is its locator strategy and value. The default locator is a unique value in detecting that object. Katalon Studio 7.6.0 onwards fully supports selector strategies supported by Appium except for Android Data Matcher. To learn more, see Find Mobile Objects.

If you prefer another locator strategy among the provided option, you can choose it and generate a new locator. Then click Highlight to see if your newly updated locator can detect the target object correctly.

  • Default locator is unique in detecting that object:
