Your memory keeps the highlights. It loses the match.
Ask any player why they lost and you'll hear about one netted forehand at 5–4. But matches turn on patterns — the eight break points before it, the second-serve returns that kept landing short. Tennasity keeps every point, so the patterns stop hiding.
Keep score. That's the whole job.
Score a tennis match point by point — any format, offline, free

Walk away with a plan
After the handshake: a plain-English match story, the turning points that decided it, and the two or three things worth training this week.
Match Story & Momentum
See the exact point where the match turned
Every Tennasity match gets a story: the momentum swings, the break points that mattered, who handled pressure and who blinked — written in plain English from your actual points, not generic stat dumps. The turning-point chart ranks each moment by how much it moved the match.
REAL APP OUTPUT — NOT A MOCKUP
Player intelligence
Stop guessing what to train next
Across matches, Tennasity builds a read on each player: what holds up under pressure, what breaks down, what opponents keep targeting. It turns that into ranked strengths, weaknesses, and a practical training focus — and you can just ask it: “Why did I lose the second set?” “What did she attack on my serve?” Answers come from your points, not from the internet.

Pro web portal
Review it on a real screen
Pro syncs every match to a web portal: season trends, rally outcomes, serve placement, head-to-heads — and one-click PDF match reports a coach will actually read. Score on the phone, study on the laptop.
THE LIVE DEMO PORTAL — REAL DATA, IN YOUR BROWSER RIGHT NOW
No camera required
Match analysis without the camera crew
Video-analysis apps are great — if you can film. That means a tripod, a permitted court, a charged second device, and processing time. Tennasity takes a different bet: the score itself, tracked point by point, already contains the story.

|---|---|---|---|

| Live sharing for family | Yes — match code, no app needed | After upload | No |

| Cost to start | Free, no account | Subscription for meaningful use | ~$10 and a pencil |

Questions, answered straight
Does Tennasity need a camera, tripod, or sensors?
No. Tennasity works from point-by-point scoring alone — you tap the score on one phone, from the stands or the bench. There's nothing to mount, film, charge, or upload, and it works on courts where filming isn't allowed.
How much does Tennasity cost?
The free tier is $0 forever: score any match format with live stats and broadcast live to spectators, with 5 full matches included and 1 per month after that. Tennasity Pro is $7.99/month or $69.99/year (about 27% less) and adds unlimited history, match stories, momentum reports, AI analysis, cloud sync, the web portal, and PDF reports.
What do I get for free, exactly?
Live scoring in every standard format, real-time stats, smart rule-based commentary, live spectator broadcasting via match code, and 5 full matches (a full match means 20+ recorded points — short tests don't count against you). Your first full match also unlocks one free Pro-level AI analysis. No account required.
Is Tennasity on iPhone?
Tennasity is on Android today; iOS is in development. Leave your email on the site and you'll get exactly one message when the iPhone version ships. The web portal and live spectator view already work in any browser, including on iPhone.
How does live score sharing work for parents and family?
Whoever is scoring shares a short match code. Anyone with the code follows the match live — every point, the score, and momentum — in a browser, with no app to install and no account to create. It's built for grandparents, travelling parents, and coaches who can't be there.
How is Tennasity different from SwingVision?
SwingVision analyses video: you mount a phone on a tripod and it produces line calls, shot speeds, and footage. Tennasity needs no camera — it builds momentum charts, match stories, and training recommendations from point-by-point scoring, and adds live sharing for spectators. Some competitive players use both; if you can't (or don't want to) film, Tennasity gives you the analysis anyway.
Can coaches use Tennasity across multiple players?
Yes. Each player gets a profile with full match history, head-to-head records, strengths and weaknesses, and a training focus. Pro adds PDF match reports, the web portal for reviewing on a big screen, and a tournament/workload planner you can share between coach and player.
Does Tennasity work offline?
Yes — scoring and stats are local-first and work with no signal at all (live broadcasting naturally needs a connection). Pro syncs matches to the cloud when you're back online.
Is Tennasity safe to use for junior players?
Player names and venues are anonymised by default before anything is sent to an AI model, AI requests run through Tennasity's own servers (no keys on the device), and the app supports biometric/PIN lock. Spectators only ever see what the scorer broadcasts: names, score, and commentary.
Do I need my own OpenAI account for the AI features?
No. Tennasity Pro includes AI match analysis, match Q&A, and live commentary out of the box, with generous monthly allowances. Power users can optionally plug in their own API key to remove limits.
Can I cancel Tennasity Pro anytime?
Yes — subscriptions are managed by Google Play and cancel in two taps. Your match data is never deleted: everything stays on your device, and anything already synced remains in your account if you ever come back.
Match point.
Your next match will tell a story either way. Keep it.
