Features by platform

Each cell shows the SDK version that first introduced the feature, or its availability status where a version does not apply.

Feature support by platform

The tables below group features by the stage of the integration journey where you typically reach for them, from core integration through release preparation.

Integrate core features

Feature	iOS	Android	React Native	Flutter
UCLID support	0.2.0	0.2.0	0.2.0	0.2.0

Screen tracking	0.1.0	0.1.0	0.1.0	0.1.0
Location tracking	0.1.0	0.1.0	0.1.0	0.1.0
Opt-in / opt-out	0.1.0	0.1.0	0.1.0	0.1.0

Add messaging channels

Feature	iOS	Android	React Native	Flutter
App inbox	1.0.0	1.0.0	Coming soon	Coming soon
In-app email collection	0.2.0	0.2.0	0.2.0	0.2.0

Prepare for release

Feature	iOS	Android	React Native	Flutter
Structured logging (ZTLogger)	1.0.0	1.0.0	Coming soon	Coming soon
Privacy manifest (Apple)	1.0.0	N/A	N/A	N/A
IDFA / IDFV support (Note 4)	1.0.0	N/A	0.1.0 (iOS only)	0.1.0 (iOS only)
GAID (Google Advertising ID)	N/A	0.1.0	0.1.0 (Android only)	0.1.0 (Android only)

Note: A version number is the SDK release that first introduced the feature. N/A means the feature does not apply to that platform; Coming soon means it is planned but not yet released. React Native and Flutter SDKs wrap the native iOS and Android SDKs -- feature availability on each platform depends on the underlying native SDK version.

Platform-specific notes

#	Note
1	`app_terminated` is an iOS-only auto-tracked event. Android, React Native, and Flutter do not track app termination.
2	Rich push on iOS requires a Notification Service Extension. On Android, rich push uses FCM data payloads and requires no additional extension.
3	Push notifications on Android use Firebase Cloud Messaging (FCM). On iOS, the SDK communicates with Apple Push Notification service (APNs).
4	IDFA and IDFV are iOS-only device identifiers. Android provides GAID (Google Advertising ID) and App Set ID instead.
5	Delivery tracking on iOS requires the Notification Service Extension and an App Group. On Android, delivery tracking works without additional configuration.
6	React Native and Flutter SDKs bridge into the native iOS and Android SDKs. Platform-specific setup (e.g., APNs certificates, FCM credentials) is still required on each side.
