How Pocket Looper Works

Take a photo of your ball

Just as it sits, from about where you will stand to hit it. No photo handy? Pick the lie from a list instead.

It reads the lie

The vision engine works out which of 14 lies you are in, how deep the ball sits — how much of it is showing above the grass — which way the grass is growing, and whether the ground is wet.

It measures the slope

Lay your phone flat on the ground by the ball, top toward the target. The motion sensors read the tilt: uphill, downhill, ball above or below your feet — and how that changes the loft, the distance and the aim.

It changes the shot to match

Carry, roll, aim and a setup tip, from one table built on launch-monitor data, so the same lie always gives the same answer. When a lie is too risky for a full swing, it tells you to play out.

Live wind, where you are standing

Speed, gusts and direction for your spot on the course — so you also see what the shot plays if it gusts.

Point your phone at the flag

The compass reads your heading and corrects it from magnetic to true north. On a phone without a compass, drag the arrow on the dial instead.

The wind is split in two

The part blowing along your line (headwind or tailwind) and the part blowing across it (crosswind). Wind in your face costs more than wind at your back gives, and the maths allows for it.

You get yards, not arrows

How many yards the wind adds or takes away, how many clubs that is, and how far left or right to aim.

It reads the air where you are

Elevation of the course, and the live temperature, humidity and barometric pressure.

It works out one thing: air density

All four change the shot the same way — through how thick the air is. The caddie works out the density once, rather than stacking “per 1,000 feet” and “per 10 degrees” rules that count the same air twice.

It adds the wind

The wind from the compass read goes on top — and thin air takes some of the sting out of the wind, too.

One number

The plays-like yardage: the distance to hit it, with how much came from the air and how much from the wind.

Put your carries in once

In Your bag, enter how far each club carries for you. Until you do, the caddie uses typical low-handicap distances.

Every club, re-worked for today

Each club’s carry is adjusted for today’s air and the wind on this shot — a long iron and a wedge are not moved by the same amount.

It picks the club

The shortest club that still gets there, with where to aim when the wind or the slope will move it.

Score each hole as you go

Strokes and putts; greens in regulation are worked out for you from those two.

Note where it went

Fairway hit, missed left or missed right — and trouble counted in shots, not yes-or-no: water, out of bounds, fairway bunkers, greenside bunkers.

Leave yourself a caddie note

What the wind did, the line that worked, what to do differently next time.
