The short version
SwingVision is a video-analysis app: you mount an iPhone or iPad on a fence or tripod, film the session, and its computer vision produces shot speeds, placement maps, line-call challenges, and tagged video highlights. It's excellent when you can film — and useless when you can't.
Tennasity needs no camera at all. Someone at the match — you, a parent in the stands, a coach on the bench — keeps score point by point on one phone. From that scoring alone, Tennasity builds momentum charts, win probability, a plain-English match story with turning points, player strengths and weaknesses across matches, and a practical answer to “what should I train next?” It also broadcasts the match live to anyone with the match code, with nothing to install.

When SwingVision is the right choice
- You want video of yourself: stroke replays, highlight reels, footage for a recruiting profile.
- You want measured ball data — serve speed, spin, depth maps from computer vision.
- You're on Apple hardware, you control the court, and mounting a device is no problem.
When Tennasity is the right choice
- You're on Android — SwingVision doesn't run there; Tennasity is Android-first.
- Matches happen where filming isn't practical or allowed: junior tournaments, club leagues, indoor courts, away venues.
- The person at the match is a parent or coach in the stands — scoring on a phone is easy; rigging a camera isn't.
- You want the why, not footage: which points turned the match, what cracked under pressure, what to train this week.
- Family wants to follow live from somewhere else, without installing anything.
Can you use both?
Yes, and some competitive players do: SwingVision for filmed practice sessions where the camera setup is easy, Tennasity for real tournament matches where it isn't. They don't conflict — one watches the ball, the other reads the match.
