Does Buildsnapper work without a signal?

Yes — Buildsnapper is built offline-first, because building sites are where mobile coverage goes to die.

What works with no signal

• Capturing photographs. Every photo is taken and stored on the device itself (where things are stored), so capture never depends on a connection. GPS, which does the geotagging, works without mobile data.
• Working through sections and plots. Progress you record is kept locally and synchronised to the cloud when the device is next online — you do not need to do anything to make that happen.

What needs a connection

• Sending a report. The report is made and sent in one go, and that needs a connection: offline, the button reads Send Report/Photos (Offline) and stays greyed out. Capture on site, then send from the van, the office or home.
• Account changes — signing up, deleting an account — need to reach our servers.

Staying signed in on site

A patchy connection will not lock you out. If the app briefly cannot re-verify your subscription or account because of connectivity, it lets you keep working — verification is given a grace period rather than an instant lockout. A genuine on-site lockout while you are paid up is a bug, and we treat it as urgent: contact support, choosing "Evidence at risk on site" (more on subscription recognition).
