Gesture Tracking

Measure captures clicks, long clicks, and scrolls automatically, so you can see how users interact with your app without instrumenting every view. Each gesture records the element it was performed on, and clicks include the text visible on that element, so a tap on a button labeled "Checkout" appears in the session with that text.

Clicks also capture a layout snapshot, a wireframe of the screen as it looked when the user tapped.

Android

Views and Jetpack Compose are both supported without setup. A gesture on a View is reported with the view's type, its id, and the text on it, so events map directly to your layouts.

Taps on composables that show text are identifiable by that text. To name a composable explicitly, set a testTag on it; the tag is reported with the gesture:

Button(
    onClick = { viewModel.checkout() },
    modifier = Modifier.testTag("checkout_button"),
) {
    Text("Checkout")
}

iOS

UIKit gestures are captured without setup. A gesture on a view is reported with the view's type, its accessibility identifier, and the text on it, read from button titles and labels. Scrolls are detected on scrollable views like UIScrollView, UIDatePicker, and UIPickerView.

SwiftUI gestures are captured too, since touches are detected at the window level.

Flutter

Gestures are detected once your app is wrapped in MeasureWidget during SDK initialization. A custom widget is tracked when it inherits from or contains one of the supported types below; other widgets are ignored.

Clicks and long clicks are detected on these widgets:

Scrolls are detected on ListView, ScrollView, PageView, and SingleChildScrollView.

React Native

Gestures are detected by the underlying native SDK, so the Android and iOS behavior above applies as is.

Performance

Android

Finding the gesture target takes 0.458 ms on average for views and 0.658 ms for composables in deep hierarchies (macro benchmark).

iOS

Finding the gesture target takes about 0.2 ms in a typical view hierarchy, and 4 ms in one 1,500 levels deep.
