Two buttons. Blue for your team, red for the opponent. One tap per point, that's it.
Your iPhone displays the full score, the watch acts as a remote. Tap the button = point for that team. One-tap undo.
Your heart rate shows in the center of the screen throughout the match. Perfect to track your intensity.
SmashScore starts a tennis workout in the Health app. Calories, exercise minutes and steps count toward your daily goals.
Same display as on iPhone: current game score, games won in the set, server underlined. Swipe left to see previous sets.
Match over? End screen on the watch with a "Rematch" button to chain the next match without reaching for your iPhone.
No watch turning off in the middle of a point. The screen stays active throughout the match via the workout session.
SmashScore is on the iOS App Store. The Watch app installs automatically if your watch is paired.
Open SmashScore on iPhone, configure the match (1v1 or 2v2). The watch syncs on its own.
Each point: one tap on your team's button. The score displays on both screens in real time.
SmashScore uses HKWorkoutSession to record each match as an official tennis workout in the Health app.
Active calories, exercise minutes, average and max heart rate: everything is in Health like any other workout. Your rings close, your activity challenges progress.
Permission requested on first use. You control which data to share.

Universal holder to attach your phone to the court fence. Touch screen usable through the glass.
