Best tennis training apps in 2026: an honest comparison

Quick verdict by job

• Stats and video from real matches and practice: SwingVision. If your club has PlaySight SmartCourts, that's the venue version.
• Feedback on your technique from a clip: sevensix (record a stroke on a tripod) or OnCourt AI (upload a photo or video and ask questions).
• Learning by watching pros and coaches: TopCourt.
• Counts and history on an Apple Watch, cheaply: TennisKeeper.
• Practicing the swing at home, traveling or in the off-season: ShadowSwing. That's our app, and this is the only job we'd recommend it for.

The comparison table

How we compared them

We didn't give anyone an overall score, because the apps do different jobs. Instead, for each one:

1. What it actually measures: the ball, your body, the racket, or nothing, and how (phone camera, Apple Watch, phone motion, venue cameras).
2. What you need: a court, a tripod, a partner, extra hardware.
3. Platforms.
4. Price as listed on the official site or US App Store on 14 October 2026. Prices vary by country and change often, so check the listing before you pay.
5. Free tier, if there is one.
6. Who it suits.

Descriptions of what each app does come from the developer's own site or listing, in their words where it matters. We haven't tested accuracy claims, so we don't repeat them.

Match and practice analysis: SwingVision (and PlaySight at clubs)

SwingVision puts your iPhone or iPad on a mount at the back of the court and works from the video. Its App Store listing describes automated analysis of shot speed, depth and accuracy, shot-by-shot and point-by-point video review, highlights with scores and stats overlaid, and coaching advice after each session. The paid plans add automated scoring, line calling and unlimited cloud storage. It covers pickleball too.

Platforms: the listing requires iOS 18 or iPadOS 18 and also lists Mac and Apple Watch. SwingVision's own site says there's no Android version yet, though an Android phone can act as a browser remote control.

Price: the in-app purchase list shows Plus at $14.99 a month or $95.99 a year, Pro at $24.99 a month or $179.99 a year, and Max at $39.99 a month or $299.99 a year. The description on the same listing quotes Pro as $179.99 a year "($14.99 USD per month)", so the monthly Pro price shows two figures. Check SwingVision's site or the app before subscribing. There's a free plan; recent release notes describe it as including 8 hours a month of HD recording.

Suits: players who get court time and want stats and video, and coaches tracking students.

PlaySight is a different thing: installed multi-angle cameras at a club or venue (the SmartCourt), with replay, AI match analytics and automated highlights, per PlaySight. You don't buy it as a player. If your club has it, use it.

AI stroke analysis from a video: sevensix and OnCourt AI

sevensix asks you to record a stroke with your iPhone, on a tripod or with a friend filming. Its listing says it uses computer vision and biomechanics to give feedback on movement, timing, impact point and swing mechanics, and lets you compare your technique to professional players. The listing shows monthly memberships at $9.99 and $14.99, yearly at $99.99 and $149.99, and single analyses at $1.99 (or 3 for $3.99, 5 for $4.99). It starts with a free trial. The listing says the app is available in English, French, Spanish and four more languages.

OnCourt AI works more like a chat coach. Per its site, you upload a photo or video for technique analysis, or ask questions about your game, and it keeps a player profile that remembers your goals and previous conversations. It's a web product. The free plan includes 10 lifetime analyses and 30 chat messages every 30 days; Pro is $19.99 a month (15 analyses and 100 messages every 30 days); Elite is $49.99 a month (50 analyses, unlimited chat).

Suits: players who want feedback on a filmed stroke without booking a lesson. Neither replaces seeing a coach in person now and then.

Learning from pros: TopCourt

TopCourt is instruction video. Its listing says it has lessons from 50+ players and coaches on strokes, strategy, fitness and mindset, in short classes you can download to watch offline on iOS. The listing covers iPhone and Apple TV; TopCourt's help center says you can also watch on a computer and other streaming devices. Basic is $179.99 a year and Gold $599.99 a year. The help center says billing is annual only, and mentions a 14-day free trial. The listing is in English.

Suits: players who learn by watching, and the off-season.

Apple Watch tracking: TennisKeeper

TennisKeeper turns an Apple Watch into a swing tracker for tennis and other racket sports. The free version logs singles, doubles, practices and lessons, with swing path, counts, steps, distance and heart rate from the Watch. Pro Edition is a one-time $4.99. The Swing Analyzer subscription ($1.49 a month or $10.49 a year, for Pro Edition users with an Apple Watch) adds speed breakdown by stroke, impact time and swing path analysis. Insights ($1.99 a month or $15.99 a year) and Live Match ($2.99 a month or $19.99 a year) are separate add-ons.

Suits: Watch owners who want counts and history without spending much.

Practicing the swing with no court: ShadowSwing

This is our app, so here's the plain version. You hold your iPhone like the grip and swing. The ball sound plays only when racket-head speed is high enough, so a slow, pushed swing stays silent. It counts swings, runs coach-voice workouts, replays the stroke in 3D, and shows racket-head speed with Pro. It covers tennis, padel and pickleball, in English, French and Spanish.

It's free with a daily swing allowance, no account. Pro is $39.99 a year; the listing also shows monthly and lifetime options. iPhone only.

As a warm-up. The guided workouts include warm-ups for tennis, padel and pickleball. Rally mode counts your swings and runs a timer, and the site lists a warm-up before a match as one place to use it. A few minutes of shadow swings in the parking lot or by the court gets your arm moving before the first ball.

Reviewing a single swing. Shot Analysis lets you play one stroke and then watch it replayed on a 3D court. You see the path the racket head traveled, where the string face was pointing through the swing, and your peak racket-head speed. You can orbit the replay and slow it down. That's the racket's path and the string face, worked out from how the phone moved. It isn't footage of you, and it doesn't track your body. Free includes a daily allowance of Shot Analysis replays; Pro unlocks unlimited ones. Speed shown on every swing outside the replay is Pro.

What it can't do: it doesn't track the ball, so there's no ball speed, spin or landing. It doesn't watch your body, so it can't check your grip, stance, footwork or contact point. It isn't a coach, it isn't a medical tool, and it doesn't replace hitting real balls.

Suits: practicing at home, traveling, the off-season and time away from the court, and coaches who set home drills. It pairs well with a camera app or a coach on court, since the camera checks the shape and ShadowSwing checks the speed; do you need a camera to practice your swing at home? explains the difference. For what to do with it, see tennis practice at home (no court) and shadow swing drills, and whether they work.

Get ShadowSwing on the App Store

What about tennis sensors?

Zepp is the one people still search for. We haven't checked other racket sensors, so we haven't listed them.

Do you need an app at all?

Not always. In our view, a wall, a basket of balls and an occasional lesson will do more for most club players than any subscription. Apps help when they answer a question you actually have: "how deep are my groundstrokes?", "is my contact point late?", "did I release the wrist?". If you don't have that question yet, start with how to practice tennis alone and come back when you do.
