Available on iOS and Android. Works fully offline. Your field team installs it once — and it's ready wherever they go.
The onesurvey mobile app is designed for people who work outside an office — in villages, markets, hospitals, retail stores, and remote field sites. It doesn't assume ideal conditions. It assumes your surveyor might have no signal, a low battery, and a queue of respondents waiting.
Survey definitions are pre-downloaded to the device. Your surveyors can go completely offline and collect data for hours — nothing is lost.
Every response is saved to an encrypted local database on the device the moment it's submitted. There's no waiting for a network call to complete. No spinner. No failure.
When any connectivity is detected — Wi-Fi, mobile data, even a brief 2G signal — all queued responses sync to the cloud automatically in the background. The surveyor doesn't need to do anything.
When enabled on a survey, the app starts recording audio the moment the surveyor opens the form. Recording continues in the background while they fill in each question. The audio file is attached to the response automatically — capturing the full interview without a second device.
Responses are stored in an encrypted local database. Sessions are managed securely — tokens are never stored in plain device storage. If a device is lost, collected responses cannot be accessed without authenticated app access.
Surveyors only see the surveys assigned to them by their organisation admin. They cannot access surveys from other teams or other organisations. Access is controlled entirely from the web admin panel — no changes needed on the device.
