The free Super Simple Logger is just distance and result.

1. Set the start distance with the − and + pad.
2. Tap Hole if it dropped, or Miss and give the leave.
3. Log the next putt; end the session when you are done.

Your putter

Tell Lagr which putter you are using and every putt you log is tagged with it, so your stats can be sorted by putter.

1. On Home, tap the golf bag button at the top right to open Your bag.
2. Type the putter’s name under Club name and tap Add. Add as many as you own.
3. Tap a putter in the list to pick it. New putts are tagged with it from then on; putts you logged earlier stay as they were.
4. Change putter any time from a logging screen: tap the Using putter line and pick another.

Details are optional. Tap the (i) beside a putter to add its brand and model, head shape, face, build, hosel, toe flow, length and grip size — any of them, now or later.

Not using a putter any more? Swipe it left and tap Retire. It moves to Retired, where Put back returns it, and its old putts still name it. Prefer not to track one? Pick “Don’t track a putter” and putts are logged with no club.

The line on the logging screen shows where you stand: grey — not tracking; green — a putter picked this session; orange — worth a look, either left over from an earlier session or you have putters and none is picked.

Course Green follows one ball start to finish — every putt begins where the last one stopped, just like a hole on the course.

1. Set where the first putt starts and hit it.
2. If it misses, place where it finished on the green; that becomes the next putt.
3. Repeat until it drops — several steps to the hole is normal for a lag.
4. The ball’s whole path is stored, so putts-to-hole-out is a real count.

Practice Green is the range drill: rake out three to five balls and hit them from the same spot.

1. Set the start distance for the group.
2. For each ball, tap Hole, or Miss and place where it finished by tapping the green.
3. The placements build a leave map — where your misses cluster.

Landscape. Turn the phone sideways for a bigger green and finer placement.

Every logger runs inside a session — start it, log your putts, then Finish session. Empty sessions are discarded, so nothing clutters your history.

Live Activity. While a session runs, iOS can show it on the Lock Screen and in the Dynamic Island, so you can glance at progress without unlocking. It ends with the session.

Guided drills that set a distance, score each ball, and move you along.

Free: the Lagr Strength Index Opener that sets your first number, plus two more.

Premium: the full catalogue — including Lag Ladder, the one the app is named for.

Film one putt and Lagr reads your stroke: backswing and follow-through timing, your tempo, whether your head or wrists moved, and how far the putter head travelled. Set your iPhone up on a tripod, facing you, and film one putt at a time.

1. On Home, tap Swing analysis (“Film one putt face-on, then log it”). You can also start it from your Apple Watch or by voice.
2. First time only: enter your height. Lagr uses it to measure how far your head moves; tempo doesn’t need it. Change it any time in Settings.
3. Set the putt distance with the − and + buttons, and stand in front of the phone.
4. Tap Start. Lagr waits until your feet and hands (and the ball, if that setting is on) are all in frame, and your watch tells you what is missing. Filming starts by itself.
5. When the screen says Putt now, make your putt. Recording ends by itself.
6. Watch your swing. Tap Accept to keep it, Replay to see it again, or Redo to film it again — a redo logs nothing.
7. Tap Log the result and say where the putt finished: holed, or the leave.
8. Your results appear. Tap See how it was read to see how each number was measured, then Another putt or Done.

Every number says how sure it is — Sure or Likely — and when a number can’t be read, Lagr shows a dash and says why rather than guess.

Your clips stay on your iPhone, and each analysed putt shows its clip in your session log. To remove one, open it and tap Delete this clip; the putt is kept. See the privacy policy for what is shared if you turn on Help improve Lagr.

Your one number: the distance, in feet or metres, where you’re predicted to have a 50% chance of holing a lag putt in 2 or fewer putts. Inside that distance, getting down in two is the expectation; beyond it, a third putt creeps in. Push the number further out and your Index goes up.

• It warms up until 12 lag putts and 12 shorter putts are logged.
• Newer putts count for more, so one bad green can’t define you.
• It won’t name a distance it has no evidence near — it tells you where to practise instead.

Line, speed & consistency. Open the Lag page for the three habits behind the number:

• Speed — whether your lags tend to finish short or run past the hole.
• Line — a flag for a systematic left-or-right miss, so a push or pull shows up.
• Consistency — how tightly your lags cluster, good or bad.

Your bracket. Wherever the number lands, Home names the level it sits in — Short Lag, then Two-Putt Range, Long Range, Deep Range, Cross-Green, Edge to Edge, and Past the Green — so progress reads as climbing a ladder, not just a number sliding.

Tips. From your Index and those three habits, Lagr writes a short tip for what to work on next. Find it on the Home tab, just under your bracket. Premium

So you can pace off a putt and have Lagr turn steps into feet.

1. Settings → Pace profile, tap Start walking.
2. Walk a measured stretch and enter how many paces you took.
3. Lagr stores your feet-per-pace; the location itself is never kept.

In a logger, pace off the distance and the start fills in — no measuring tape.

In Settings you choose how distances read and how finely you log:

• Units — feet/inches or metres/centimetres.
• Accuracy — the step you place to (e.g. 0.5 ft or 0.15 m).
• Format — how a distance is shown and spoken.

Everything is rounded only where it’s shown, so switching units never moves your data.

Home leads with your Index bracket and a tip about what to work on next.

Stats — free: the Lagr Strength Index and make percentage by distance.

Stats — Premium: strokes gained, putts to hole out, and three-putt avoidance.

By putter. Filter your stats to a single putter to compare your gamers head-to-head — make %, three-putt avoidance and the rest, per club. (The screenshots here are from an earlier build and don’t show the putter filter yet.)

Your level sets the yardstick. Strokes gained — and how much room a challenge gives you before it resets — are measured against a reference standard you pick in Settings → Your level. It never touches your Index, your putts or your brackets; it only decides what “even” means for the stats that compare you to a bar:

• Beginner — new to putting, or a higher handicap: a gentler bar, more room to grow.
• Club — a regular club golfer: the middle standard.
• Pro — a scratch or professional standard: the toughest bar.

Pick the one that matches how you putt today. You can change it any time; it only moves the compare-to-a-bar stats, never your logged putts.

Every session you’ve logged, newest first. Tap one to see each putt — start, result and leave — and edit or delete anything that went in wrong.

Settings is also where you look after your data:

• Export your putts to a CSV — one row per putt, ready for a spreadsheet or a backup you keep. It’s yours, and nothing leaves the device unless you send it.
