Sitemark works on any phone browser. The mobile experience is built for the field — large tap targets, offline capability, and a layout you can navigate with one hand while holding a grade rod. No app store required to get started. Open the browser, log in, and you are working.
Log grade shots in the field without a signal. Sitemark queues your data locally and syncs automatically when you reconnect. No dropped records, no manual re-entry.
Grade percentage, pipe run, cut and fill, concrete bag count — all calculator tools run entirely in the browser with no server round-trips. Open the tool, get the answer.
Pull up calibration records, last-check dates, and equipment notes from the cab or the trench. The full equipment registry is accessible from any device with a browser.
Install Sitemark as a web app for the fastest access — one tap from your home screen, no app store required.
Must use Safari. Chrome and other browsers on iOS do not support Add to Home Screen.

We launched Sitemark as a web app to keep prices low and ship improvements fast. A web-first approach means every update reaches every user instantly — no waiting for App Store review cycles. It also lets us focus engineering resources on the product itself rather than maintaining parallel codebases. Native apps are in development and will add deeper OS integration, push notifications, and enhanced offline capability. In the meantime, the web app is fully functional and works on every modern phone.
