About PocketCaddie

The no-video swing coach.

PocketCaddie turns your iPhone into a personal swing coach. No tripod. No camera. No setup. You pocket your phone, swing normally, and get real feedback after every session — the kind of feedback that used to require a camera, a coach, or both.

Free to download. Premium starts at $9.99/month with a 7-day free trial.

What it is

A swing coach that lives in your pocket.

PocketCaddie is built for range golfers who want real feedback without the friction of setting up a camera. If you’ve ever wanted to know whya swing felt off, or whether your tempo is anywhere near a Tour player’s, but couldn’t be bothered to plant a tripod every time you hit a bucket of balls — this is for you.

We use your iPhone’s built-in motion sensors as the primary instrument. The phone goes in your pocket. You swing. The app picks up the motion, isolates each swing, scores it, and gives you something to work on. Connect an Apple Watch and AirPods if you have them, and the picture gets richer — but the iPhone alone is enough to start.

How it works

Three layers of sensing. Use what you have.

PocketCaddie’s coaching gets deeper with each Apple device you add. Start with just the iPhone — it’s the whole engine on its own. Add a Watch or AirPods later when you want more.

1. iPhone in your pocket

Your iPhone’s accelerometer and gyroscope detect each swing, measure tempo and rhythm, estimate power, and track consistency across the session. This is the core engine. No other device required.

2. Apple Watch (Premium)

A Watch adds wrist-side motion and heart-rate data. We use it to measure wrist action, kinetic sequencing, and how your body is actually performing across the practice session.

3. AirPods (Premium)

AirPods with motion sensors add head-stability tracking — one of the quietest, most-overlooked fundamentals in the swing. If your head moves, we’ll see it.

What you get

Real metrics, plain-English coaching, every swing.

Swing Score (0–100)

A composite score built from tempo, smoothness, power, and consistency. One number that tells you how a swing rates — so you can see a session at a glance and know which swings to study.

Tempo grade (A–F)

Your backswing-to-downswing ratio, graded against the Tour-pro 3:1 benchmark. We tell you exactly where you sit and what to feel to get closer.

Power tier

From Easy through Smooth, Strong, Explosive, and Pro-level. A clear sense of how hard each swing was actually loaded, not just how hard it felt.

Hand Speed (mph)

A real measurement of how fast your hands are moving through impact. Track it over time to see speed gains land.

Pattern detection

We watch for common swing flaws — reverse pivot, early extension, over-the-top, and others — and tell you when we see one, along with a feel-based drill to fix it.

Session Wrapped recap

After every session you get a slideshow that surfaces your money swing of the day, your session trends, and a coaching insight to take to the next bucket.

Getting started

Seven steps. Under two minutes.

  1. 1

    Download from the App Store

    Free. iOS 17 or later required. Search “Pocket Caddie” or use the button below.

  2. 2

    Open the app and sign in with Apple

    One tap. We don’t need your email or a password. Sign in with Apple gives you account portability across devices.

  3. 3

    Tap the big Start button

    This puts the app into recording mode. From here on, you don’t need to look at the phone.

  4. 4

    Pocket your phone — front pocket works best

    Front pocket of your pants is ideal. The sensors are most reliable when the phone is held against your thigh and doesn’t shift around.

  5. 5

    Take your swings — normally

    Hit your bucket the way you would on any range visit. The app detects each swing on its own — no taps between shots, no calibration ritual.

  6. 6

    Tap to end the session

    When you’re done, tap the End button. The app finalizes your scores and pulls up the recap.

  7. 7

    Watch your wrapped recap

    A short, swipe-through slideshow shows you your money swing, your session trends, and one coaching insight to carry into your next round.

FAQ

Quick answers to common questions.

Do I need a tripod or camera?+

No. That’s the whole point. PocketCaddie uses motion sensors, not video, so there’s nothing to set up. Pocket your phone, swing, done.

Does it work indoors?+

Yes. The app works anywhere you can take a swing — at home, at a simulator, in a net, or on the range. No GPS or location signal required.

Do I need an Apple Watch?+

No. The iPhone alone is enough to give you a Swing Score, tempo grade, power tier, and hand speed. An Apple Watch (and AirPods) add Premium-only depth like wrist action and head stability, but they’re optional.

Where do I put my phone?+

Your pocket — the front pocket of your pants works best. Keep it snug so the phone doesn’t shift mid-swing. That’s the most reliable position for the motion sensors.

Is my data private?+

Yes. Swing sessions are processed on-device first, and we don’t share your data with advertisers. See the Privacy Policy for the full detail.

What iPhone do I need?+

Any iPhone running iOS 17 or later. The motion sensors are standard across modern iPhones — no special hardware needed.

How much does Premium cost?+

$9.99 per month or $89.99 per year, billed through the App Store. New subscribers get a 7-day free trial. Cancel anytime.
