Swing analysis for iPhone and Android
A hundred balls.
Not one word back.
Visco changes that. Stand your phone up behind you and keep hitting. A few seconds later it shows you which fault is costing you the most shots, and hands you a drill for it.
Everything is worked out on your phone. The videos stay where they are.
- Steady head
- Hips sliding sideways
- Knee bend through the swing
The moment of impact
You will never see it.
Your camera will. Sixty frames a second, and Visco measures 33 points on your body in every single one. Including the ones that fall between two blinks.
Per swing
- 33body points tracked
- 21values measured
- 1sentence on what to work on
- 0videos leave your phone for the measurement
From the last ball struck to a finished analysis: four to nine seconds.
How it goes
What a session at the range looks like.
AI-generated01Record
No start button
Phone on a tripod, two to four meters behind the ball. There is no start button. Visco reads the speed of your hands and knows when a real swing is coming. Practice swings don’t set it off.
AI-generated02Measure
21 values, measured on device
Tracking runs on your own device, frame by frame. That turns into 21 values, each judged against what is normal for the club in your hand.
AI-generated03Understand
Two things at most
Two cards. What went well, and what is next. Never more than two things at a time, however much else stands out.
AI-generated04Practice
The reason, not just the name
A drill for every fault, with the reason it is that one. Next time the number tells you whether it worked.
The measurement
21 values. You’ll understand every one.
Other apps put “early extension” and “shoulder tilt” on the screen. If you knew what those meant, you wouldn’t need the app.

The score
One number for the whole swing.
The score is the average across every value that could be measured cleanly. You will never see 100. That is deliberate.

- Building40–59
- Solid60–74
- Strong75–89
- Tour90–100
More than measuring
The rest of the app.
AI-generatedA coach with a memory
Two sentences, no guesswork
It knows your last sessions, your numbers and the drills you are working on. How it explains things follows your handicap — a beginner hears different sentences than a single-figure player. Its knowledge comes from a vetted library, and guessing is off limits.
AI-generatedHands free
Next. Stop.
On the range you don’t want to keep walking back to the phone. Say “next” or “stop”. And your score is read out to you, so you never have to look.
AI-generated45 drills
The drill gets measured too
There is one for every one of the 21 values, and the one you get treats the cause rather than the symptom. For many of them the camera watches: you find out whether you did the drill right — not just that you did it.
Where it goes wrong, on your body
Eight areas
19 of the 21 values sit somewhere on your body — and that is exactly where the app puts them, head to feet. Rhythm and sequence get no marker: they measure a ratio over time and belong nowhere. And whatever the camera did not see stays blank rather than turning red.
Am I getting better?
Twelve weeks at a glance
Your curve over the weeks, best scores per club, a web across six areas. Two swings run side by side, even from different sessions. And at the end of the month the app tells you the month instead of listing it again.
Showing up counts
Points for showing up
Points are for turning up, not for playing well — a scrappy swing counts as much as a clean one. Out of that grow seven ranks and fifty badges. Each badge tells you how many other people already have it.
Clubhouse
Every golf app shares scores.
Visco shares swings.
The video with the skeleton drawn onto it. The score as a number you can hold against someone else’s. And the option for a friend to stop at the exact frame and tell you what they see.
- Feed, applause, comments
- Form check at a point in the video
- Flights of up to four players
- Clubs with group chat
- Challenges and duels
- Leaderboard at your course
- Arriving at launch.
Limits
What Visco won’t do.
A bad recording must not turn into a confident number. Too dark, too far round to the side, too short, and Visco says so. Rather than inventing a 68 that you then believe.
No number without a basis
If the recording isn’t good enough you get the reason instead of a score. Values that couldn’t be measured read “not measurable”. Never a guess.
Never more than two faults
Even when six stand out. Take six corrections onto the mat with you and you will make none of them.
No angles in the coaching
“Your shoulder turns 180 degrees, 10 short” helps nobody with the next ball. The coach tells you what to do differently, not what the instrument printed.
No invented expertise
What the coach knows about golf sits in a curated library drawn from TPI, PGA and peer-reviewed biomechanics. If it isn’t in there, it says so.
Data
Your videos stay with you.
It is worked out on the phone
Body tracking and the numbers happen on your device. Nothing has to travel anywhere to be measured.
Uploading is your call
That switch is the only one in the app that is off out of the box. And the server checks it, not just the app.
Recordings clear themselves
Swing videos stay on the device for seven days. The app clears them on the next launch. Keeping one means saving it yourself or starring it for the archive.
No movement history
When a session starts, Visco takes one rough look at where you are, matches the course and forgets the coordinate. The name is what gets saved.
Price

About us
An hour with a pro costs 80 to 120 euros. Your phone already has a camera.
Visco is built in Germany. The idea behind it is unremarkable: everything you need to measure a golf swing has been sitting inside every phone for years. It was simply never packaged so that somebody playing off 32 could do anything with it.
We don’t train an AI of our own. We put existing pieces together. The body tracking comes from Google, the explanation from a language model, and the golf knowledge from a curated library, so the coach has nothing to invent.
We are not trying to show you the most numbers. We want you to leave the mat knowing what to do differently next time.
- Accurate
- We only talk about what was measured.
- Plain
- Ordinary words, no jargon.
- Calm
- Clearer beats more.
Before you sign up
The usual questions.
What do I need besides my phone?
Something to hold it. A cheap tripod or a clamp does the job. The camera goes two to four meters behind the ball, on the target line. No sensor, no extra hardware, no second subscription.
Am I too bad for this?
If anything it is the other way round. The bigger the fault, the more clearly it measures. The coach matches its language to your handicap: further down it explains every term, further up it gives you the numbers straight. If you are allowed on a course, you are in.
Does it work if I play left-handed?
Yes. Handedness is asked during setup and carries through the whole analysis. Without it, left-handers would have the wrong side of the body measured every single time.
Is the range enough, or do I need a course?
The range is enough. So is a net, or a winter bay. What gets measured is your body, not the ball. It only needs enough light and a clear view of you.
Do my videos end up online?
Not by themselves. The analysis happens entirely on your device. A video leaves the phone only when you share it, and that switch is off out of the box.
How long does an analysis take?
Four to nine seconds. You can carry on hitting in the meantime; the camera keeps running and picks up the swings that follow.
Does this replace my pro?
No. A pro sees things no camera measures, and can put hands on you and move you into position. Visco is for the time in between. For the Tuesday evening on the range when nobody else is watching.
What is Visco not?
Not a launch monitor. Ball speed, spin and carry need a radar, and we are not one. Not a medical device either: if something hurts, see a doctor rather than an app.
When is the app coming?
It is running on real devices in testing right now. Leave your address and you will get exactly one message the moment it lands in the store.
Back at the range next week.
This time you’ll know.
One email when Visco is in the store. After that you won’t hear from us.
