Opening spring 2027

The GPS hole map: hole 1 at Conwy from the tee, 391 yards to the pin, with distances to the back, middle and front of the green, the planned drive, and yardages to the bunkers.

Record as much or as little as you like

Three ways to record, and you can switch from round to round. More detail means sharper stats; any detail beats guessing.

  1. 1

    Hole by hole

    The quickest way in

    Score, putts, fairway, green in regulation, up and down, penalties. The quick way to start knowing your numbers.

  2. 2

    Shot by shot

    For the full picture

    Lie, club, strike, start line and curve for every tee shot, approach, chip and putt — so you know why a shot went wrong, not just that it did.

  3. 3

    GPS

    Tap where it finished

    Mark each shot on a map of the hole as you walk. Distances and positions are worked out for you.

GPS hole maps

Every hole, drawn and measured

An illustrated map of each hole — fairways, bunkers, water and trees — with your live distance to the front, middle and back of the green and to everything in between.

  • “Plays like” yardages that allow for uphill and downhill shots.
  • Drag the flag to today’s pin position; everything re-measures.
  • Tap where each shot finished — every distance is measured for you.
The green close up, with the flag and the yardages to the front, the flag and the back of the green.
Tiger 5 avoidable mistakes per round and a score-to-par trend over five rounds.

Stats that point somewhere

See where the strokes really go

Not a wall of numbers: the handful that explain your score, compared with tour averages and tracked round after round.

  • Tiger 5 — the avoidable mistakes: bogeys on par 5s, doubles, three-putts, bogeys from inside 150 yards, blown easy up and downs.
  • Where shots are lost — bad shots by part of the game, and whether it was the strike, the start line or the curve.
  • Practise next — what to work on first, why, and a drill to do it.

Round planner

Plan the round before you tee off

Add the clubs in your bag and how far you carry them, then plan each hole tee to green, with where each shot lands drawn on the map. Your plan is waiting on the course, hole by hole.

The round planner on hole 1 at Conwy: driver 235 yards, then a 7 iron of 154 yards to the green.
