iPhone & iPad · Instant swing replay
SwingLoop turns two devices you already own into an instant replay system for the range. One films. The other plays every swing back in slow motion, seconds after you make it — on its own, without either of you touching a screen.
How it works
About a minute to set up the first time, and no setup at all after that. Here is the whole of it.
Clamp the filming device to a tripod, or prop it against your bag — anywhere it can see you from head to feet. The second one goes where your eyes already go between shots: on the mat, on the cart, against the bucket. Face-on or down-the-line, both read fine.
The replay device puts a code on screen. Scan it, or just tap the device in the nearby list. There is no account, no cable and no settings screen to work through — and at a range with nothing but sky, turn on your Personal Hotspot and the two find each other over that instead.
SwingLoop watches for the swing itself. It arms as you settle over the ball, records through impact, and cuts the clip once your follow-through has come to rest — so the whole move is in there, top to finish. Between shots there is nothing to press, nothing to start and nothing to check.
A beat after the ball is gone, your swing is on the other screen: slow motion, looping, holding there until the next one replaces it. Set the delay anywhere from instant to fifteen seconds so it lands exactly when your eyes come up.
A look inside
Large type, hard contrast, and controls big enough to hit with a glove on. Every screen is meant to be understood in the half second between shots — including the one lying in the sun on the mat beside you.

Features
A golf-specific pose model runs against the camera buffer on the device itself: hands joined below the shoulders, a settled address, the wrists travelling, the return through impact, a follow-through that finishes. Reaching down for a ball or taking a practice cut doesn’t set it off.
Set the delay anywhere from instant to fifteen seconds — measured from the end of your swing rather than from when the video lands, so transfer time never moves it. Then watch at full speed, half or quarter, looping until your next swing replaces it.
Watching face-on is disorienting when the replay is reversed. One switch flips it horizontally, so what you see moves the way you just did.
Sensitivity, how long you hold at address before it arms, and how much follow-through it keeps — plus delay, speed and mirroring — are all adjustable live, from either device, mid-session.
Privacy
SwingLoop is built the way it is because of where it gets used. The pose detection runs on the filming device itself, using Apple’s on-device Vision framework — no frames and no body landmarks are ever uploaded. Clips go straight from one of your devices to the other, and live only on the one that plays them. There is no account, no library in the cloud, and nothing here for us to look at.
Read the privacy policyApple Vision, reading the camera buffer in place. Frames are never copied off the phone to be analysed somewhere else.
Swing clips move over your own local network or a direct device-to-device link — never through a server of ours.
We don’t ask for your name, your email or your handicap, because we have nothing to attach them to.
Questions
Yes — that is the whole idea. You can’t watch your swing on the phone that is filming it, and walking over to a screen after every shot is exactly the habit SwingLoop is built to remove. Any two iOS devices work: two iPhones, two iPads, or one of each.
Yes. Turn on Personal Hotspot on the filming device and join it from the other, or let the two connect to each other directly — SwingLoop looks for a nearby device on its own. Either way the connection is between your two devices and nothing else.
They shouldn’t. Detection needs the full shape of a golf swing — a settled address, real travel through the ball, and a follow-through that comes to rest. If your bay or your tempo needs it, the sensitivity and both hold times are adjustable.
Yes. Frame yourself head to feet where you can, keep the filming device fixed rather than handheld, and it behaves the same as it does outdoors.
Both. The detector reads body pose rather than raw motion, so either view works. Most people start face-on, since that is the one that is hardest to picture from the inside.
The replay device holds your twenty most recent swings and drops the oldest as new ones arrive. Exporting and sharing individual clips is not in this version — SwingLoop is built around watching the swing while the feel of it is still fresh.
A tripod is ideal, but anything that keeps it still and upright works — a phone stand, a bag pocket, a ball bucket. What matters is that it does not move between shots and that it can see you from head to feet.
Not yet. Version one is iOS only, because the on-device pose detection is built on Apple’s Vision framework.
