OverRally: Tennis Watch Stats

New: Progress. Watch your swing speed, impact timing and form move across every session you've played. One month free.

OverRally is the easiest way to see what your tennis swings are actually doing.

Press start on your Apple Watch and play. Every swing is read on your wrist as you hit it, and the whole session is waiting on your iPhone when you walk off. No phone on court, no filming, no tagging afterwards.

EVERY SWING, AUTOMATICALLY • Forehands, backhands, serves and volleys recognised on the watch itself • Nothing to press between points — just play • Works with your phone in your bag

YOUR SESSION ON ONE TIMELINE • Swing speed — the flow, with your average and range • Contact timing — early or late at impact, in milliseconds • Heart rate — the whole session, with your average • Four charts on one time axis, so you can see what happened together • Tap any swing to see its path in 3D

SEE WHAT REPEATS • How tightly each stroke repeats, not just its average • Swing speed, contact timing and swing length spreads, stroke by stroke • The variation is where the improvement is

KEEP SCORE ON YOUR WRIST • One tap a point — games, sets, tennis scoring • Every point tied back to the swings you hit to win it • No phone, no scorecard, no leaving the court

TRACK YOUR TENNIS • Log matches, lessons and practice sessions • Record scores, win/loss, play time and notes • See your month at a glance on the calendar • Climb six levels — Wall, Drill, Rally, Set, Match, Season — by swinging, not by opening the app

YOUR GAME, YOUR DATA • Sessions sync to your account — sign in with Google or Apple • Light and dark themes

SUBSCRIPTION PLANS • Free: record as much as you like, plus one session opened in full • Pro: every session in full, forever, and everything added to Pro as it lands Subscriptions renew until cancelled and can be cancelled anytime in your account settings.

An Apple Watch is required.
