Build it at home.
Keep it handy on the course.

Use the website now

Open a tool, enter what you know and leave unknown measurements blank. The phone layouts use individual club cards and numeric fields. A computer gives you more room to compare results and print. Installing a shortcut is optional.

Prepare for a weak signal

1. While connected, open the tools directory.
2. Wait for the footer to say Tools ready offline. If it reports an incomplete download, use its retry button while connected.
3. Save your entries with the tool’s Save button. Keep a PNG, printed card or exported backup as well.
4. Before relying on it for a round, switch your device offline and reopen the tools directory in the same browser. Check that your saved card loads.

The root homepage and external links need a connection. Offline tools live under /en/. A home-screen icon alone does not confirm that the offline download finished.

Add a shortcut if you want one

iPhone or iPad

Open the tools directory in Safari, open the Share menu and choose Add to Home Screen. If your system offers Open as Web App, you can use that option. Menu wording can vary with your iOS version.

Android

Open the tools directory in Chrome, open the browser menu and look for Add to Home screen or Install app. You can keep using the browser if that option is unavailable.

After opening the installed shortcut, check its own offline status and saved data. A separate browser or app context may not share the draft you entered elsewhere.

What is saved, and where?

Saving keeps a draft in that browser on that device. It is not a cloud account. Clearing website data, changing browsers or storage cleanup can remove it. Export a backup before switching devices or clearing storage.

The distance card and wedge matrix support a manual JSON export/import workflow. Transfer the file yourself, review it in the destination tool and choose Save there. A PNG is a reference image; it cannot restore editable fields.

Prefer a paper card?

Choose Print / Save as PDF, select US Letter or A4 and inspect the preview. A blank card is useful for recording shots during practice. Only enter carry when you know where the ball first lands; total distance includes its bounce and roll.
