Does Tennis Time need an iPhone?

No. Tennis Time runs on Apple Watch on its own. It is installed through the App Store and keeps your matches on the watch and in your own iCloud.

When does the free trial start?

The 10 days of Pro start with your first finished match, not when you install the app.

Get started with Tennis Time on Apple Watch

Tennis Time is a tennis score keeper that runs on Apple Watch on its own. Install it from the App Store, type your name once, and the Home screen takes you to a match, a warmup, your history, your statistics and Settings.

Install the app

Tennis Time is a watch-only app: there is no iPhone app to set up. Open the App Store on your Apple Watch, or on iPhone, search for Tennis Time and install it. It needs an Apple Watch with watchOS 11 or later.

Enter your name

Open Tennis Time on your Apple Watch. A short opening clip plays; tap to skip it.
On the Your name screen, tap Name and enter your name.
Tap Continue. It stays dimmed until the name has at least one letter.

The Your name screen in Tennis Time on Apple Watch, with a Name field and a Continue button — The first screen asks only for your name.

Your name is how the watch labels your side of every match, and how you appear in statistics and rankings. You can change it any time in Settings.

Your 10-day trial

Right after your name, a Your trial screen explains the deal once: 10 days of Pro, free, counted from your first finished match, not from the day you install. Tap Got it.
