Feedback on every swing

Swing. Look down. Know.

About a second after contact the card is on your phone: exit velo, bat speed, launch angle, spray, and the slow-motion clip. No waiting for a session report.

The card

Exit velo and bat speed first, launch and spray a moment later, carry from the flight. Big numbers, one glance, back to the tee.

The clip

Every swing is recorded in slow motion. Tap the card to watch it, step back through the session, share the good ones.

Every swing counts

Hits, misses and foul tips all get a card, so you see what's really happening in a round, not just the highlights.

StoneCast™ · our swing analyzer · beta

Your swing, connected to your results.

Numbers tell you what happened. StoneCast™ shows you why: how your body moved on the swing that went 91, and what was different on the one that went 84.

Seconds, not minutes

The body breakdown is ready before your next round. No uploading, no waiting for someone to tag it.

Body to outcome

See how your hip and shoulder turn, your sequence and your hand path show up in bat speed, exit velo and ball flight.

What changed

Your best swings against the rest, side by side, so practice has a target instead of a feeling.

StoneCast™ is in beta. It gets smarter with every swing hit on Rivo. The comparison above is an example of the layout, not a measured session.

Track your progress

For every hitter

From the first tee-ball swing to varsity.

Youth mode

Built for kids as young as 6. A small swing is measured as carefully as a big one, and the card speaks their language.

Families

One box, every kid in the house, separate profiles and progress. Parents' swings count too.

Teams and facilities

One roster across the program, one history per athlete wherever they hit. Several boxes on one account · coming soon

Simple setup

Plug in. Open the app. Hit.

The box sits behind the hitter, facing the net. It sets itself up in seconds and finds your phone on its own.

How it works

Radar for the speeds. Cameras for the angles, the video and StoneCast™.

Rivo measures exit velo and bat speed with radar and reads launch, spray and your body with cameras. Cards are made in the box in about a second. Every number shows how confident it is. If Rivo isn't sure, it says so instead of guessing.
