Basic stats are fairways, greens and putts. Advanced stats are tee and approach misses, scrambling, sand saves, chips, by par, per course and what to work on. A free tier that has only some of them reads “limited”. Yardstick’s front, back and carries show wherever the green is mapped, about 9 in 10 US courses; Canadian courses show the middle for now.

Sources for every cell

Competitor free tiers as published by each company, checked 16 October 2026: 18Birdies, SwingU, Golfshot, Hole19, TheGrint, and each app’s help center and App Store page.

Every yardage

Front, middle, back and the carries. On your phone and your wrist.

  • Front, middle and back

    Straight from where you stand, on a satellite photo of the hole, wherever the green is mapped. That's about 9 in 10 US courses; Canadian courses show the middle for now.

  • Water and bunkers

    The nearest water and bunkers on your next shot are labelled on the map with what it takes to reach them and to carry them.

  • Touch to measure

    Drag a target anywhere to see how far it is and what it leaves you, with a circle for your usual miss.

  • On your Apple Watch

    Raise your wrist for front, middle and back and the hazards ahead, measured by the watch’s own GPS. The round is saved to Health as a golf workout.

Every stat

Basic or advanced. All of it free.

Keep just the score, or track as much as you like. Stats that other golf apps put behind a subscription are all here.

  • Basic

    Score a routine hole in two taps, with fairways, greens and putts.

  • Advanced

    Tee club, where the approach missed and from how far, first-putt distance, scrambling, sand saves, chips and penalties.

  • What it tells you

    Where your strokes go, what to work on, how you play each par and each course, every figure beside your own usual.

  • Honest numbers

    A stat appears only when your rounds can back it up. The handicap is an unofficial estimate, labelled as one.

No ads

No ads. No account. Nothing to unlock.

No banners on the hole, no pop-ups between holes, no upgrade screens. Open the app at the course and play. There’s nothing to sign up for.

Why it’s free

Free isn’t a trial here. It’s how the app is built.

  1. 1

    We map every course ourselves

    Our own system maps the courses, so we don’t rent course data from anyone and pass that bill on to you.

  2. 2

    It runs on your iPhone

    Your yardages, scores and stats are worked out on the phone in your pocket, not on our servers. So your rounds and your location never reach us.

  3. =

    So nothing is behind a paywall

    Every yardage, on your phone and your wrist. Every stat. No subscription, no trial, nothing to unlock.

How it measures

Are the maps right?

92%
We tested our maps on 5,400 holes at 350 US courses our system never saw while it was being built. On 92% of holes, our green centre landed within 3 yards of an independently mapped green.

That measures the map. Your phone’s GPS adds a few yards of its own.

The middle
From where you’re standing to the centre of the green, in a straight line.
Front and back
The near and far edges of the green, on the line from you to its centre. Where a green isn’t mapped yet you’ll see a dash, never a guess.
Carries
How far to reach a water hazard or bunker, and how far to clear it.
No signal
Yardages are worked out on your iPhone, so they work without signal. The satellite photo needs a connection; when it can’t load, the yardage stays live.
When a hole looks wrong
Tell us the course and the hole. Reports from golfers are how the maps get better.
And the rest

The small things that make a round easier.

Ask Siri

With AirPods in and the phone locked, Yardstick answers out loud.

“Yardstick yardage.”
Hole 7: 142 to the middle, 131 front, 155 back.

On the Lock Screen

The hole and its yardage sit on your Lock Screen and in the Dynamic Island all round. The Play golf control on the Action button opens straight to your round.

Fly the hole

Tap the hole’s name to fly it tee to green in 3D, with the carries on the way, then drop back into your round.

Score in two taps

A routine hole is two taps and you’re walking to the next tee. Got one wrong? Fix any round, any time.

Send the card

Share the round’s scorecard to your group, with a sentence about how it went.

Who makes it

I’m Aydin. I play most of my golf with the same few friends, and every app we tried wanted a subscription for things that aren’t hard. A front and back yardage is a distance formula. A hazard carry is a line crossing a shape. What those subscriptions really pay for is a rented course database.

So I mapped the courses myself, all 13,977 of them, and built the app my group wanted: every yardage, every stat, no ads. Since we don’t rent the data, there’s nothing to charge you for.

Aydin, who makes Yardstick

Your rounds stay on your iPhone.

No account, no tracking. The app runs on your phone, so your rounds and your location have nowhere else to go.

Is your course here?
