Tennis video analysis apps compared

A search for a tennis video analysis app returns tools that do very different jobs. Some measure the ball. Some judge your swing. Some are drawing tools for a coach. Decide which of these you want before you compare prices.

We make one of the apps below, TennisAI. We have not tested any of the others. Everything about them comes from their public listings and company pages, read on 4 November 2026 on the US storefront, and we give no app a score.

What to check before you choose a tennis analysis app

Who each tennis video analysis app suits

SwingVision: whole matches and ball data

Choose it if you want numbers from real points: shot speed, depth, rally length and score, plus live line calls. You mount an iPhone or iPad at the back of the court with a full view. Its plan table gives every plan shot stats, and starts shot-by-shot technique review, scoring and match stats at Pro. Its listing also advertises coaching after each session. On 4 November 2026 it had 4.7 stars from about 5,000 ratings and an Editors' Choice badge on the US App Store.

It is also the one app here with an independent check that we read. In a peer-reviewed study of 6 college students across 4 matches and 1,065 strokes, it showed high agreement with human analysts for most variables, and closer agreement from the optimal camera angle. The sample was small, and the authors warn about errors linked to camera angle.

TennisAI: stroke feedback from an uploaded clip

Choose it if your question is about the technique of your forehand, backhand or serve, and you want to ask follow-up questions in a chat. You upload a clip and get a score out of 10, with separate stroke scores and feedback. A stroke that is not in the clip shows as "Not in video" and is not scored. The Progress tab shows session history and estimated NTRP, UTR, WTN and ITN numbers, which the app labels as not official.

Its limits: it is iPhone only, it does not score volleys, returns or slices, results vary with video quality, camera angle and lighting, and full access needs a paid plan. Its listing does not advertise live line calls or match stats. Its Privacy Policy says videos are processed temporarily and deleted automatically after analysis. See what the TennisAI app includes.

sevensix: buy one analysis at a time

It records a stroke and gives feedback on timing, impact point, movement and mechanics, with a comparison to professional players. You can buy one analysis for $1.99, three for $3.99 or five for $4.99, which suits a low-cost first try. It had 4.2 stars from 68 ratings on 4 November 2026. Release notes for version 4.0.2 say its AI Coach feature was removed, so check the current listing if you want a chat coach.

TorqAI: joint-level detail and more strokes

Its listing describes 17 tracked joints, a 3D view, drills and a comparison with pros, and it covers volley, slice and overhead as well as forehand, backhand and serve. That is wider than the three strokes TennisAI scores, which matters if your volleys are the problem. It offers 5 free stroke analyses a month on iOS. It had only 4 ratings on 4 November 2026, so there is little public feedback to go on.

SportAI Open: no app to install

This web app covers tennis, padel and pickleball, and was announced in open beta in September 2026. You upload a video, or record one in the browser on a mobile device. It is a sensible option to look at if you do not use an iPhone. A beta can change, and its announcement does not mention pricing.

OnForm, PlaySight and Tennis Australia Technique: tools for people

In these apps, a person does the analysis. OnForm is built for coaches who give video feedback and message athletes. Its store text focuses on golf, baseball and softball, and its FAQ names tennis among technique-focused sports. PlaySight is a free app with clips, slow motion and drawing tools, and its listing says it works with or without a SmartCourt. Tennis Australia Technique offers side-by-side and overlay comparison, but its last version is dated October 2019, so check that it runs on your phone.

Apps we left out

Newer apps such as 10Ace, SwingIQ, Tennis-IA and ServeBot also offer stroke feedback. On 4 November 2026 their US listings showed two ratings or fewer, so we had too little public information to say who they suit.

Two names you may still see are gone. The Coach's Eye notice says it "has been retired and is no longer a working service". OnForm announced in May 2021 that it had acquired Hudl's Technique app, with a shutdown later that summer and a migration tool to OnForm.

Run this one-clip test before you pay

A listing cannot tell you how an app handles your video. This test can. It takes one practice session, and for some apps it needs a paid month, so avoid paying for a full year first.

1. Film three minutes of one stroke, with your whole body and racket in the frame. Our guide to filming tennis covers where to put the phone. For an app that tracks matches, film the way its instructions say.
2. Count your strokes by hand. If the app lists or counts strokes, compare its number with yours. A large gap means it struggled with your video.
3. Pick one piece of feedback and check it yourself. If the app says you are late, pause at contact and see whether the ball is in front of your body.
4. Record a second clip from the same spot in the same light, and a third from a worse angle. The two similar clips should give similar results. A large change on the third tells you to keep your setup fixed.
5. Write down one thing to try in your next session because of the feedback. If you cannot, the app has not helped yet, whatever the score says.

Treat any score as a starting point. To see what the technology can and cannot judge, read what AI swing analysis can tell you. If SwingVision and TennisAI are your final two, we compare them row by row in TennisAI vs SwingVision. If you would rather not pay at all, you can review your match video by hand.
