A putting tracker for Apple Watch

Reaching for your phone between putts is why most people stop logging. Lagr puts the logger on your wrist, so your phone can stay in your pocket or your bag.

How logging works on the wrist

  1. Turn the Digital Crown to set how far the putt is.
  2. Tap Hole if it drops.
  3. If it misses, tap Miss, turn the Crown to set how far from the hole it finished, and confirm.
  4. Keep putting. Each putt joins the session as you log it.
The Lagr Simple Logger on Apple Watch: a putt from 10.0 feet, with Hole and Miss buttons.
Set the distance, then Hole or Miss.
Logging a miss on Apple Watch: the leave set to 0.5 feet, with a Confirm button.
After a miss, set where it finished.

Your stats live on iPhone

The watch is for logging. Each session syncs to Lagr on your iPhone, which is where your Lagr Strength Index, make % by distance and the rest of your numbers are worked out. Here is what each one measures.

Challenges on your wrist

Guided challenges run start to finish on the watch: a briefing before you begin, a card at each station telling you where to stand and how many balls to hit, and a summary at the end. The Lagr Strength Index Opener is free, and it is the quickest way to get your Index. More on lag putting and the Index.

What's free

Logging on the watch is free, and so is logging on your phone. Lagr Premium adds Course Green and Practice Green, the rest of the challenges, advanced green features, and tailored feedback drawn from your own misses.

Lagr needs an iPhone running iOS 17 or later.
