TennisAI vs SwingVision: features, prices and who each one fits

We make TennisAI, so we are not neutral. We have not tested SwingVision. Facts about it come from its US App Store listing, its website and an ITF report, all read on 4 November 2026. Facts about TennisAI come from its listing, Terms and Privacy Policy.

In the table, "Not listed" means the public pages we read do not advertise the feature. It does not prove the feature is missing.

TennisAI vs SwingVision: feature table

SwingVision's App Store description shows Pro as $179.99 a year, or $14.99 a month. That is the yearly plan expressed monthly, and the separate monthly Pro plan is $24.99. Prices vary by country.

Where SwingVision is stronger

SwingVision does live line calling and match stats. TennisAI's listing does not advertise either one. If you want an in or out call while you play, or a score and stat sheet after a match, SwingVision is the one of these two that offers it.

• Live calls. Its listing and version notes advertise real-time audio line calls and Apple Watch challenges with slow-motion replays. The ITF report describes an optional on-court tablet that can keep score and show electronic line calls.
• Ball data. It advertises shot speed, depth, accuracy and rally length, automated stats and scoreboards on video, and highlights with the dead time removed.
• A free plan. Its FAQ says a free account gets 8 recording hours a month with automated stats, highlights and line calls. Its plan table lists scoring, match stats and line calls for both sides of the court from Pro upward.
• More devices. It runs on iPhone, iPad, Mac, Apple Vision and Apple Watch.
• Public track record. On 4 November 2026 it had 4.7 stars from about 5,000 ratings and an Editors' Choice badge on the US App Store. Our listing has too few ratings to show a star rating.
• Verified ratings. Its version notes mention showing verified NTRP and WTN ratings through USTA Connect.

SwingVision's FAQ says that with an ideal setup and 60 frames per second, its line calling is 97% accurate for close calls within 10 cm (about 4 inches) of a line, and its shot speeds are accurate to within 10%. SwingVision's Swing Court page also says its line calls are over 99% accurate. These are the company's own figures, and we did not read an independent line-calling test. The ITF (now World Tennis) issued an approval report in October 2025, and that report says approval does not establish accuracy.

One independent check does exist. In a peer-reviewed study of 6 college students across 4 matches and 1,065 strokes, the app showed high agreement with human analysts for most variables, and closer agreement from the optimal camera angle. The authors call it trustworthy and warn about errors linked to camera angle.

SwingVision's FAQ says it reports the ball's average speed along its flight, which it says reads 10% slower than radar. Do not compare its numbers with speeds shown on TV.

Where TennisAI fits

TennisAI does a narrower job. You record a practice or match with your phone, upload it, and get an overall score out of 10, with separate scores and feedback for forehand, backhand and serve. A stroke that is not in the clip shows as "Not in video" and is not scored.

• Stroke focus. Feedback covers swing path, timing, contact point, body position, footwork, balance, control, consistency and power.
• Chat. You can ask the AI Coach about strokes, drills, match preparation and your training routine. Chats are not stored permanently.
• Progress. The Progress tab shows session history, average and technique scores, and estimated NTRP, UTR, WTN and ITN numbers. These are estimates from your video analyses, and the app labels them as not official.
• Video handling. The Privacy Policy says videos are processed temporarily, deleted automatically after analysis and not stored on our servers.
• Lower list price. As of November 2026 in the US, it costs $12.99 a month or $39.99 a year, against $14.99 or $95.99 for SwingVision Plus. This is not a like-for-like comparison, because SwingVision's plans include ball tracking and stats.

The limits are real. It is iPhone only, and it scores only those three strokes. AI output is an automated estimate and can be wrong, and results vary with video quality, camera angle and lighting. Its listing does not describe a free plan: the download is free, and full access needs TennisAI Pro. The analysis is for training and does not replace professional coaching. You can see the screens and full feature list on the TennisAI page, or read how to use the app step by step.

TennisAI or SwingVision: a decision rule

Choose by the question you want answered. If you need an in or out call or a match stat, choose SwingVision. If you only want feedback on your forehand, backhand or serve, either can work, so compare the two.

Try this before you pay for a year:

1. Before your next session, write down the two questions you most want answered.
2. Match them against the table above.
3. If either needs a line call or a match stat, start with SwingVision's free plan, and check whether you need Pro.
4. If both are about technique, film three minutes of that stroke. Pause the clip at contact, and compare what you see with what the app tells you. Use a weekly or monthly plan for this test.
5. In your next practice, try one change from the feedback. Film the same stroke from the same spot and see whether the contact point moved.

Can you use both apps?

Yes. One sensible split is to record matches in SwingVision and upload a short practice clip of one stroke to TennisAI. Two subscriptions only make sense if you would use both every month, and you probably need just one. See also our list of SwingVision alternatives and our comparison of tennis video analysis apps.
