3. Other Notes
The current version operates as a standalone Watch app, but we plan to enhance functionality by linking it with the iPhone in the future.
The app has been thoroughly tested, but we cannot guarantee 100% functionality. When using the app in an official match, please use a backup timepiece as a precaution.
Please note that some organizing bodies for tournaments or competitions may not permit the use of smartwatches by referees.
