Zepp Tennis alternatives: what replaced the sensor

If your Zepp sensor has stopped syncing, or the app no longer lets you in, you are not alone. Zepp’s tennis sensors are discontinued, and this guide covers what happened and the best Zepp Tennis alternatives you can use instead.

A quick disclosure first: we make ContactFrame, so weigh our pick accordingly. Everything we say about the other products comes from their own websites and app store pages, checked in November 2026. Prices and features change, so check before you buy.

What happened to Zepp Tennis

Zepp made two tennis sensors: the original square Zepp 1 (later called Zepp Tennis Classic) and the round Zepp Tennis 2. Each clipped to the butt cap or handle of your racket and logged your strokes by type, along with swing speed, spin, sweet-spot hits and session intensity. It could also capture a 3D view of your serve and sync with phone video. HEAD also sold a sensor built by Zepp for its own rackets.

Here is what we could confirm in November 2026:

• Retailers such as Tennisnuts list both Zepp tennis sensors as discontinued and sold out.
• The Zepp Tennis Classic app is still on the UK App Store, but its last update was version 2.2.5, on 17 August 2017.
• A newer Zepp Tennis app, made for the Zepp 2 sensor, still appears in App Store search. Whether it still works, we could not confirm.
• A report on the Tennis Warehouse forum says the apps have been unsupported for years.

You may have read a specific date for when Zepp switched off its tennis servers. We could not confirm one from Zepp or any independent source, so we are not giving one. What matters in practice: you cannot buy the sensor new, and you should not count on the app.

From racket sensors to phone video

Zepp was part of a wave of racket and wrist sensors from roughly 2014 to 2017. Babolat, Sony and HEAD all had one. All of them are now discontinued, and we found no major-brand racket sensor on sale in November 2026. If you owned another, see our guides to Babolat Play alternatives and Sony Smart Tennis Sensor alternatives.

Why it faded tells you what to buy next. A sensor on the racket only knows how the racket moved. It can count forehands and estimate a swing speed, but it never saw the ball after it left the strings. It could not tell you whether that forehand landed deep, landed short or landed in the net.

A phone on a tripod behind the baseline sees the whole court. It can measure the ball itself (speed, spin, where it bounced, in or out) and the player (where you stood and how you moved). For most club players, “where did it land and was it in?” is a more useful question than “how fast was my racket?” For the full list, see what AI tennis video analysis measures.

The trade-off is honest: you need to set up a tripod, and a phone cannot read your racket’s swing speed the way a sensor on it could.

How we judged the Zepp alternatives

We looked at what you need to buy, what each option measures, the price (in GBP where the store shows it), which phones it runs on and whether it is still supported. Here is the short list:

1. ContactFrame: best overall for club players who want ball and body data from one phone
2. SwingVision: best for iPhone and iPad owners who want a video app today
3. UNFORCE: best for Android users who want to upload a session for a debrief
4. Apple Watch tennis apps: best for scoring and activity from the wrist
5. Pocket Radar: best for serve speed on its own

1. ContactFrame: best overall Zepp replacement for club players

ContactFrame films your session with one phone on a tripod behind the baseline. No sensor, no wearable, no court hardware. For every shot it measures ball speed, spin in rpm (shown only when the reading is solid), where the ball bounced and an in, out or close call, and it scores each shot out of 100 for shot quality. It also tracks your movement: distance covered, where you stood and how well you recovered to the middle.

On the Pro plan, shot mechanics tracks body points through your swing, gives swing scores for things like preparation, contact and footwork, shows a stick-figure replay of each contact and gives you one Next fix with a drill. That is the closest thing to what Zepp’s swing data was trying to do, with the ball’s result attached.

• Needs: a phone and a tripod.
• Platforms: iOS and Android at launch. ContactFrame is not out yet; there is a waitlist.
• Price (Nov 2026): Free £0 with 15 minutes of recording a month; Basic £9.99 a month with unlimited recording; Pro £17.99 a month with shot mechanics.
• Good at: ball and body in one app, serve placement, trends session after session. It leaves out a number it is unsure of rather than guess.
• Watch out for: a small free tier, no Apple Watch app, no racket swing speed, mechanics only for the player nearest the camera, and in/out is for coaching, not official line calling.

2. SwingVision: best for iPhone and iPad owners today

SwingVision is the established tennis video app. You film from an iPhone or iPad behind the baseline and it tracks shots, ball speed, placement, line calls and the score. If you need a Zepp replacement this week and you use Apple devices, this is the one to try. Details are on swing.vision.

• Needs: an iPhone 11 or newer on iOS 18+, or an iPad on iPadOS 18+, plus a mount. An Apple Watch is optional.
• Platforms: iPhone, iPad, Mac, Vision Pro and Apple Watch. No Android app.
• Price (UK App Store, Nov 2026): free tier with 8 recording hours a month; Pro £24.99 a month or £179.99 a year.
• Good at: a free tier far more generous than ours, Apple Watch control, scoring and full-court line calls on Pro.
• Watch out for: Apple only, and free recordings are kept for 7 days. Its plan page lists shot stats and heatmaps for speed, depth and consistency; it does not list spin readings, movement or swing mechanics.

3. UNFORCE: best for Android users who want a debrief

UNFORCE (formerly AceSense) lets you film a session with one phone and upload it for a summary, clips and a debrief, with a way to share that debrief with a coach. It covers tennis and several other racket sports.

• Needs: one phone.
• Platforms: Android and web. Its site says the iOS app is not publicly available yet.
• Price (official site, Nov 2026): Pro €19 a month or €190 a year, for 20 analyses a month and videos up to 30 minutes. A 7-day trial is offered to eligible users.
• Good at: works on Android now, coach sharing, more than one sport.
• Watch out for: priced in euros, and we could not confirm from its homepage whether it measures ball speed or calls lines.

4. Apple Watch tennis apps: best for scoring and activity

If what you liked about Zepp was the record of every session on your wrist, a watch app is the nearest thing. TennisKeeper turns an Apple Watch into a swing counter, recording shots, swing path, steps, distance and heart rate. Ballboy and Tennis Scoreboard keep score from the watch.

• Needs: an iPhone and an Apple Watch.
• Price (US App Store and official sites, Nov 2026): TennisKeeper is a free download with paid add-ons (Pro Edition US$4.99 one-off). Ballboy is free for 6 watch-tracked matches, then US$9.99 a year or US$24.99 for life. Tennis Scoreboard is free with a US$9.99 upgrade.
• Good at: cheap, quick to start, nothing to set up on court.
• Watch out for: wrist motion and manual scoring only, so no ball placement, no in/out and no video. TennisKeeper was rated 2.8 out of 5 from 40 ratings when we checked.

5. Pocket Radar: best for serve speed alone

If the number you miss is serve speed, a radar measures it directly. The Pocket Radar Smart Coach pairs with an app that records video with the speed on it. See our serve speed radar guide for the options.

• Needs: the radar, plus a phone for the app features.
• Price (official US site, Nov 2026): Smart Coach US$399.99; Ball Coach US$299.99.
• Good at: a device built for one job.
• Watch out for: speed only. No placement, spin or in/out.

How to choose a Zepp tennis alternative

• “Am I improving?” Pick a video app that tracks the same measures session after session. See how to track your tennis progress.
• “What did my swing do?” Video with body tracking, such as ContactFrame Pro, or a watch app if you only want swing counts.
• “How fast is my serve?” A radar, or a video app that measures serve speed alongside placement.
• “What’s the score?” A watch scoring app does it cheaply.

Verdict

The Zepp sensor was a good idea held back by where it sat: on the racket, blind to the ball. The best Zepp replacement for most club players is phone video, and ContactFrame is our pick because it puts speed, spin, placement, movement and swing mechanics in one app on iOS and Android, priced in pounds. It is launching soon, so join the list for The Lab. If you need something this week and own an iPhone, use SwingVision meanwhile.

Common questions

Is Zepp Tennis still supported?

Zepp’s tennis sensors are discontinued and retailers list them as sold out. The original Zepp Tennis Classic app is still listed on the UK App Store, but its last update was version 2.2.5 in August 2017, and a Tennis Warehouse forum report says the apps have been unsupported for years.

When did Zepp shut down its tennis servers?

We could not confirm a date from Zepp or an independent source. The only shutdown date we found came from a company selling a rival sensor, so we have not repeated it.

What is the best replacement for the Zepp tennis sensor?

For most club players, a phone video app is the better replacement, because it measures the ball as well as the stroke. ContactFrame is our pick once it launches; SwingVision is the established option on iPhone and iPad today.

Can an Apple Watch replace a Zepp sensor?

Partly. Apps such as TennisKeeper count shots and record wrist movement, and others such as Ballboy keep score. None of them sees where the ball landed or whether it was in.

Does any app measure racket swing speed like Zepp did?

Some Apple Watch apps record swing data from the wrist. Video apps such as ContactFrame measure ball speed and spin instead, which tells you what the swing actually did to the ball.
