DISTRIBUTION OF TIZEN-BASED WATCH APPS HAS BEEN DISCONTINUED

Compatibility

Galaxy Watch Studio (GWS) is currently in beta. As it continues to develop, the availability of some features may change and some features may not be fully functional. Learn about the supported Tizen OS, watches, features, and Java versions for Galaxy Watch Studio.

InformationGWS (.gwd) files created in the latest version of GWS cannot be opened by older versions of GWS. GWS files created in older versions of GWS can be opened by newer versions of GWS. For example, GWS 1.7.1 files cannot be opened in GWS 1.6.2. However, GWS 1.6.2 files can be opened in GWS 1.7.1.

Supported Tizen OS and Watches

The following table shows the GWS version with the Tizen OS and the watch types that it supports. The table also shows the factory-installed Tizen OS on the watch (on some watches, the Tizen OS may be upgraded).

²Upgradable to Tizen 4.0.0.2.

³Upgradable to Tizen 3.0 and 4.0.0.2.

⁴When watch is upgraded to Tizen 3.0 or higher.

InformationWhen you upgrade or downgrade the OS on your watch, you may need to regenerate your distributor certificate in order to test your watch faces on the updated watch.

InformationFor devices using Tizen 4.0 or later, by law, you must notify the user about personal information used in the watch face. When the app is launched, you must allow the user an option to allow or not allow access to personal information. Therefore, a separate TPK file must be generated for Tizen 4.0 and later and for Tizen 3 and earlier.
Galaxy Watch Studio provides an option to generate separate TPK files for these versions. Samsung suggests appending "_TW4" to the TPK file name for devices using Tizen 4.0 and later and appending "_TW3" to the TPK file name for devices using Tizen 3 or earlier. Upload one or both files to support the appropriate devices.
