Tennis Swing Analysis on SwingVantage turns a single phone video of your tennis stroke into a prioritized report: your number-one fix, the drills that groove it, and a retest to confirm progress. It is built for tennis and works free from any phone.
Step by step
- 1
Record one swing
Film a single tennis stroke from the side in good light, with your whole body in frame. A 3–10 second clip is perfect — slow motion is not required.
- 2
Upload it
Open /tennis-swing-analysis (or the Upload screen), choose Tennis, and drop in your clip. You can also record straight from the app with on-screen framing help.
- 3
Get your report
In moments you get a plain-language breakdown: what is working, what is costing you the most, and the single change to make first.
- 4
Start with your one fix
The report leads with your highest-priority fix. Ignore the noise and work that one thing — it is ordered by impact for a reason.
- 5
Run the drills
Each fix comes with drills you can do at home or before practice. Add them to your plan so they show up in Today’s Tasks.
- 6
Retest to prove it
After a few sessions, upload a fresh swing and compare. SwingVantage shows you whether the fix actually moved — closing the loop.
What Tennis Swing Analysis does
Tennis Swing Analysis reads a single video of your tennis stroke and turns it into an actionable plan. Instead of a wall of numbers, it tells you the one thing to change that will help the most right now.
It is designed around a simple promise: one fix, one plan, one retest. You are never left guessing what to work on.
What it looks at for tennis
For tennis, the analysis focuses on the things that actually change outcomes:
- Serve mechanics — toss, trophy position, and racquet-drop timing.
- Forehand and backhand swing path and contact point.
- Body rotation, the kinetic chain, and weight transfer.
- Footwork, balance, and recovery.
Problems it helps with
Players most often come to Tennis Swing Analysis to work on:
If you are not sure what is wrong, that is exactly what it is for — upload a swing and let it find your biggest opportunity.
- Building a more reliable serve
- Cleaning up a one- or two-handed backhand
- Generating more topspin and power
- Fixing late or cramped contact
Who it’s for
Beginners, improving amateurs, parents helping a young athlete, and coaches who want a fast second opinion. You do not need launch monitors, sensors, or any special gear — just your phone.
How accurate is it?
Every result that comes from watching your video is a confident, well-reasoned starting point — not a lab measurement. Treat it like a sharp-eyed coach giving you their read, then confirm it on the range or court.
Accuracy depends on what you give it. A clear, well-lit, side-on video of a full swing produces a far better report than a dark, cropped, or partial clip.
When the analysis is unsure, it tells you so rather than inventing a number. Honesty over false precision is a core principle.
Get the most out of it
- Film the same angle each time so your retests are comparable.
- Work one fix at a time — chasing five changes at once is the fastest way to get worse before you get better.
- Retest every week or two, not every rep. Real change shows up over sessions.
- Pair it with the drills and your practice plan so the work actually happens.
Your video and your privacy
Your swing is yours. To generate a report, frames from your video are sent securely to our AI analysis provider — that is what reads your body positions and motion.
We do not sell your data and we do not run ads. Your sessions are tied to your private account and synced across your devices so you can pick up where you left off.
You can review, export, or delete what you create from the Data center at any time.
Frequently asked questions
What kind of video gives the best results?
Film from the side (down-the-line or face-on), in good light, with your whole body and the full swing in frame. Hold the phone steady or prop it up. A 3–10 second clip of one swing is ideal — you do not need slow motion.
Do I need special equipment to analyze my tennis swing?
No. A modern phone camera is enough. There are no sensors to wear, no launch monitor, and nothing to calibrate. Just film a clear swing and upload it.
How fast do I get my results?
Most reports come back within moments of uploading. You will see your top fix first, then drills and a plan underneath.
Can I analyze my serve as well as groundstrokes?
Yes. Film whichever stroke you want feedback on — serve, forehand, or backhand — and choose Tennis. Film one stroke type per clip for the cleanest read.
Can it tell if I’m actually improving?
Yes — that is the point of the retest. Upload a new swing later and SwingVantage compares it to your earlier one so you can see whether the fix took hold, instead of guessing.
Is it free?
Yes — you can analyze a swing for free, no equipment beyond your phone required. Some advanced tools and history depth are part of a paid plan, but the core "see your one fix" experience is free to try.
Is this the same as a real coach?
It is a powerful complement, not a replacement. It gives you an instant, consistent read any time of day and great drills to work on; a coach adds human feel, feedback, and accountability. Many players use both.
