Your surveyors shouldn't have to think about internet. With onesurvey, they don't. Data saves instantly on-device and syncs automatically the moment signal returns.
Most survey tools are built for offices — they assume you'll have a stable internet connection when collecting data. In the real world, field teams work in areas with no signal, weak 2G connections, or intermittent Wi-Fi. When the connection drops mid-survey, data gets lost.
onesurvey is built differently. The internet is treated as optional — not required — at the point of data collection.
onesurvey has worked in areas with zero mobile signal. Responses collected offline are indistinguishable from those collected online once they sync.
The sync process is designed to be resilient. If a sync attempt fails (for example, if signal is lost mid-upload), responses remain safely queued on the device and the sync retries automatically. No response is ever lost due to a failed upload attempt.
Media files — photos, videos, audio recordings — are also queued and uploaded automatically when connectivity returns. Large files are handled gracefully without blocking other responses from syncing.
Responses stored locally are encrypted — they are never written to plain text on the device. Even if a device is lost or stolen, collected responses cannot be read without authenticated access to the app session.
