Frequently asked questions
Is Grassy or 18Birdies better for golf GPS?
It depends on your priorities. 18Birdies is a strong fit for golfers seeking a broad digital-caddie and improvement suite across free and Premium tiers. Grassy is a strong fit for iPhone golfers who want advanced visual planning, supported-course terrain detail, and course ranking and discovery included together.
Does Grassy include plays-like distance?
Yes. Grassy can show measured or plays-like distance adjusted for available wind, elevation, temperature, and altitude. Conditions may not be available for every round.
Does Grassy offer swing analysis or automatic shot tracking?
Neither is a current Grassy Course GPS claim. The current 18Birdies feature page promotes AI swing analysis. Golfers who prioritize automatic shot tracking should confirm that feature through a specialist app’s current official documentation.
