Installing the app and working offline

CountTooling runs in any modern browser with nothing to install — but you can install it, and once you do, it keeps working offline. That matters when the plans are in a basement, a mechanical room, or anywhere the signal drops.

Install it (add to home screen)

Installing gives you a real app icon and a full-screen, chrome-free window — it launches like a native app, straight to your plans.

• iPhone / iPad (Safari): open CountTooling, tap Share, then Add to Home Screen.
• Android / desktop Chrome: use the browser's Install option — an install icon in the address bar, or Install CountTooling from the browser menu.

It's the same app either way — your projects, counters, and line types are all right where you left them.

Working offline

Once a takeoff is loaded, you can keep working without a connection:

• Counting, measuring, and marking up all work offline.
• Your changes auto-save locally every few seconds, with backups, so nothing is lost.
• When you're back online, cloud projects sync up automatically.

The Save status indicator in the top bar tells you where things stand — it shows when your work is saved locally and synced to the cloud, so you're never guessing.

One thing to know on iPhone: an installed app keeps its own storage, separate from Safari. So the first time you use the installed app, sign in and open your takeoff while you still have a connection — after that, it's available offline.

On a tablet

CountTooling is touch-friendly: single-finger pan, pinch to zoom, and long-press for the context menu. Marking up plans on a tablet in the field feels natural, and a takeoff you start on a tablet picks up on your desktop (and vice versa) when projects sync.
