Built for the decision in front of you
The map works like part of the round
The live satellite map helps you read front, middle, and back distance, choose a hazard or layup target, understand both legs of the shot, and keep the score moving.
Measured or plays-like
Switch views to account for available wind, elevation, temperature, and altitude when those conditions can be resolved.
Plan hazards and layups
Drag a target to any layup or hazard point, read golfer-to-target and target-to-green distances, use adaptive arcs, and see a club suggestion when your bag is configured.
Overhead and 3D views
Reframe the hole from above or move into a 3D flyover to understand shape, landing areas, and the route to the green.
Supported-course terrain detail
Where available, explore interactive 3D hole terrain and 3D LiDAR Green Books with slope heat and break-direction arrows.
Round context that stays useful
Review your own hole history, set today’s pin, optionally auto-advance, add notes, and see weather when it is available.
More than a rangefinder
Your round stays connected to the course.
A course is not just today’s yardage. It is where it sits on your list, what your friends thought, the holes you remember, and the next place you want to play.
- Rank the courses you play and revisit your list after the round.
- See friend activity and discover courses through golfers you trust.
- Carry your own hole history, notes, and scorecard into the course context.
- Compare Grassy with specialist GPS and tracking apps before you choose.
Straight answers
Frequently asked questions
Is Grassy Course GPS free?
Yes. No GPS subscription is required. The Course GPS Beta planning tools are included for everyone in Grassy.
Does Grassy Course GPS work at every golf course?
Grassy does not make a universal coverage claim. A GPS round depends on course geometry and scorecard availability. Interactive 3D terrain and LiDAR-derived green maps appear only on supported courses.
What does plays-like yardage include?
When the required information is available, plays-like distance can account for wind, elevation, temperature, and altitude. You can switch back to measured distance at any time.
Does Grassy automatically track every shot?
No. Automatic shot tracking is not a current Course GPS claim. Grassy currently focuses on live distance, visual planning, scoring, terrain, and round context.
Can I use Grassy satellite maps offline?
Grassy does not promise offline satellite maps. Plan on having a data connection for the complete map experience.
How does Course GPS fit with course rankings?
Course GPS lives in the same app as your ranked course list, friend activity, lists, notes, and course discovery. The round becomes part of a longer course story instead of a separate utility.
Is Grassy available on Android or a golf watch?
Not currently. Grassy requires an iPhone with iOS 18.0 or later and does not claim Android, Apple Watch GPS, or Wear OS GPS support.
Does Grassy include hazard and layup distances?
Yes. During an eligible Course GPS Beta round, you can drag a target to a hazard or layup point and see golfer-to-target plus target-to-green distances. Adaptive arcs and club suggestions are included as well.
Does Grassy include 3D green maps?
Supported courses can include interactive 3D hole terrain and 3D LiDAR Green Books with slope heat and break-direction arrows. This detail is included for everyone where supported, but it is not universal.
