Free golf apps with 3D course maps: what's actually free in 2026

Free 3D course maps are rarer than the app-store screenshots suggest: 18Birdies, Hole19 and GolfLogix all keep detailed 3D green contours and slope reading behind a paid tier, and Golfshot's free flyover previews are the closest thing to a genuine exception. If you've been hunting for an app that hands you full 3D slope reading at no cost, the honest answer is that one doesn't really exist — what does exist is worth being specific about.

Full disclosure: this is published by FlyAway. FlyAway's own green elevation and slope tool is also gated to Premium — the same pattern as everyone else in this comparison, not an exception to it.

What "3D course map" actually means, and why it's usually paywalled

Two different things get marketed under the same phrase. A 3D course flyover is a rendered preview of a hole from above — useful for planning a strategy before you tee off, and comparatively cheap to produce since it doesn't need to update per pin position. 3D green contour and slope reading is a live, per-pin model of how a green breaks, built from detailed elevation surveys — expensive data to capture and maintain, which is exactly why it sits behind a subscription almost everywhere: the survey cost has to be recouped somehow, and slope reading is the single feature golfers report being most willing to pay for.

What's actually free right now

Golfshot is the real exception among major golf apps: full-course 3D flyover previews are available on its free tier, letting you preview a hole's shape and hazards before you play it — confirmed directly by Golfshot's own product blog announcing the feature, not a third-party claim. Its more granular in-round 3D green-slope tool remains part of Golfshot Pro, at $99.99/year.

18Birdies, Hole19 and GolfLogix all follow the same shape: free tier gets GPS distances and a flat or satellite course view, detailed 3D green contours and slope reading sit behind their respective premium subscriptions. None of the three currently offers a free full 3D green-reading tool.

FlyAway's own green elevation and slope reading is Premium-gated too — worth saying plainly rather than presenting it as a free differentiator it isn't. What is free is GPS distances to the front, center and back of the green, and the course map view in the mobile app, matching the industry's free-tier norm rather than beating it. The 3D course and green view specifically exists in FlyAway's mobile app, not the web version — plan on downloading the app if that's the feature you're after.

What you can actually use during a competitive round

This is where the paywall question becomes secondary to a rules question. USGA/R&A Rule 4.3a permits distance-measuring devices in stroke and match play, but it draws a hard line at anything beyond distance: a feature that reads slope, factors in wind, or recommends a club crosses into advice the rule doesn't allow — and the rule is written around the feature being active, not whether you look at the screen. An app with a slope-reading mode switched on breaks the rule even unused. Local rules can go further and restrict or ban DMDs entirely for a given competition, which is worth checking on the notice board rather than assuming your usual app is fine everywhere.

For a casual round, none of this matters — read the slope, use whatever tool you have, play faster. For anything with a posted local rule, distance-only mode is the safe default.


Want GPS distances and a course map that respects what you can actually use on the course? See FlyAway's course map — free tier included, Premium for the slope-reading layer, same as the rest of the category.

Frequently asked questions

Are 3D golf course maps actually free?

Mostly no. 18Birdies, Hole19 and GolfLogix all gate 3D green contours and slope reading behind a premium subscription — free tiers get a flat 2D or satellite view with GPS distances. Golfshot is the genuine exception: full-course 3D flyover previews are available on its free tier, though its more detailed in-round 3D green tool is still part of Golfshot Pro.

Is it legal to use a 3D slope-reading app during a competitive round?

USGA/R&A Rule 4.3a permits distance-measuring devices in general, but it explicitly excludes using a feature that gauges slope, wind or gives club-selection advice — an app or watch with that feature switched on breaks the rule even if you never open the screen. Local rules can restrict DMDs further or ban them outright, so check the notice board before you rely on any app's slope tool in competition.
