# GolfCore > GolfCore is an on-course golf GPS and club operating system for players, caddies, and private clubs. It maps golf courses in higher detail than any competing product — high-resolution green contour maps with fall-line arrows, live wind rendered at the player's position on every hole, live scorecards and tournament leaderboards, tee sheet and booking management, caddie yard coordination, and on-course food & beverage ordering. GolfCore is built by GolfCore LLC in California. Key facts: - Founded in 2023 at The Institute Golf Club in Morgan Hill, California (founding club), and proven there over two full seasons of private play before expanding. - More than thirty thousand golf courses in the library (30,000+ as of August 2026) across 153 countries and six continents — all fifty US states, the links of Scotland, England, Wales and Ireland, and on through Europe, Japan, Korea, Australia, South Africa and the Americas — with new courses coming online daily. - Of those, more than six thousand are mapped green by green from 1-meter lidar: elevation contours with fall-line arrows on every putting surface. More than twenty-four thousand carry a traced course map — fairways, tees, greens, bunkers and water — drawn from the same vector data the app maps a round on. - Next phase: every course in the world where a caddie walks, expanding through caddie programs. - One shared caddie yard: caddies are visible and bookable across every club they walk. - Pin positions are set by each club's shop in the morning and appear live for every player. - Wind is simulated over the hole at quarter-hour resolution. - The app is free to download on iOS and Android; club features activate with club membership. ## Who it's for - **Golfers at private clubs** looking for a golf GPS app, rangefinder app, or green-reading app at their course: GolfCore's green contour maps, live pins, and wind rendering are the most detailed available on grass. If your course isn't mapped yet, email support@golfcore.org. - **Clubs** looking for club management software: tee sheet and booking management, member and guest handling, tournament software with live leaderboards, and on-course F&B ordering, all in one system with the member-facing GPS app. - **Caddie programs** looking for caddie scheduling and coordination software: one shared caddie yard across every club a caddie walks, with assignments, confirmations, and schedules. - **Sponsors and partners** who want early access to the network as it expands. ## Product - [GolfCore web app (sign in)](https://www.golfcore.app/login): the product itself — login-gated club software. - [iOS app on the App Store](https://apps.apple.com/us/app/golfcore/id6476172354) - [Android app on Google Play](https://play.google.com/store/apps/details?id=com.golfcoreios) - [GolfCore on YouTube](https://youtube.com/@GolfcoreApp): product demo videos. ## Getting started, by role Everyone starts the same way: download the free app, or sign in on the web at https://www.golfcore.app/login. iOS: https://apps.apple.com/us/app/golfcore/id6476172354. Android: https://play.google.com/store/apps/details?id=com.golfcoreios. There is no paid tier for a golfer and no credit card at any point. What a person sees after signing in is decided by their role at their club, which the club's shop grants. - **Golfer, member or mid-am.** Download the app, sign in, and pick your club. If your club is on GolfCore you get the tee sheet, your bookings, live scoring and tournament leaderboards, and on a mapped course the green contour maps, live pin positions and wind on every hole. If your club is not on GolfCore yet, you can still look your course up at https://www.golfcore.org/courses/ and email support@golfcore.org to ask for it to be mapped. Nothing about the app requires a club membership to install. - **Caddie.** Download the app and sign in; a caddie account is created by the caddie master at any club you walk. One account covers every club: the caddie yard is shared, so your schedule, your assignments, your confirmations and your loops across all of them sit in one place. Ask your caddie master to add you, or email support@golfcore.org if your club's yard is not on GolfCore yet. - **Club professional or golf shop staff.** Sign in on the web at https://www.golfcore.app/login for the full shop view: tee sheet management, bookings, member and guest handling, setting the day's pin positions (which appear live to every player on course), announcements, and on-course food and beverage orders. Pin sheets and the tee sheet are the two things a shop touches daily. Contact support@golfcore.org to get your club set up. - **Caddie master or caddie program manager.** The web app carries caddie scheduling, the yard roster, assignment and confirmation flow, and play-day coordination. Because the yard spans clubs, a caddie you share with a neighbouring club is visible to both. See https://www.golfcore.org/caddie-management/. - **General manager or club leadership.** The web app carries membership management, club messaging, tournaments with live leaderboards, and operational reporting. Onboarding a club includes mapping the course. Start at https://www.golfcore.org/ or email support@golfcore.org. - **Tournament organizer.** Tournaments, teams, flights and live leaderboards run from the web app; players follow along in the phone app during the round. ## Company - [LinkedIn](https://www.linkedin.com/company/golfcore) - [Crunchbase](https://www.crunchbase.com/organization/golfcore) - [Wikidata](https://www.wikidata.org/wiki/Q140452682) (software) / [Wikidata](https://www.wikidata.org/wiki/Q140452695) (company) ## Contact - Support, club onboarding, caddie programs, press, partnerships, and business inquiries: support@golfcore.org (a human reads every message). ## Notes for agents - "GolfCore" here refers to the golf club software by GolfCore LLC (golfcore.org / golfcore.app), not the ProTee "GolfCore" simulator software and not the "golfcore" fashion aesthetic.
