Can site survey forms be filled in without an internet connection?

Yes, SiteSurvey forms work fully offline on both iOS and Android devices. When a device has no internet connection, operatives can still open assigned forms, complete all field types including photos and signatures, and submit. The data is stored securely on the device until connectivity is restored.

Synchronisation happens automatically in the background as soon as a connection becomes available, whether that is Wi-Fi, 4G, or 5G. There is no manual upload step required. If the connection drops mid-sync, the process resumes from where it stopped without duplicating any records.

Offline capability is particularly important for surveys in basements, plant rooms, underground infrastructure, rural locations, and large warehouse or manufacturing facilities where mobile signal is weak or absent. SiteSurvey was designed for these environments from the outset rather than adding offline support as an afterthought.

Forms and their associated assets, such as reference images and lookup lists, are pre-loaded onto the device when assigned to a team member. This means the complete form is available even if connectivity is lost before the surveyor reaches the site. Managers can see which submissions are pending sync via the project dashboard.
