Collect responses anywhere — even offline

No Wi-Fi? No signal? No problem. Enable offline mode and your forms keep working. Submissions are queued on the device and synced automatically when connectivity returns.

Works without a connection

When offline mode is enabled, the entire form — fields, logic, assets — is cached on the device. Respondents can open and fill out the form with zero network access. No app install required.

Automatic submission queue

Submissions made offline are stored securely on the device. Each entry is timestamped and tracked. When connectivity returns, they are replayed in order — automatically, in the background.

Background sync with retry

Queued submissions sync as soon as the device reconnects. Failed submissions retry with exponential backoff — up to 5 attempts. Permanent failures are flagged so nothing is silently lost.

Real-time status indicators

Respondents always know what's happening. A non-intrusive banner shows offline status, pending submission count, sync confirmations, and any errors — all accessible and screen-reader friendly.

You're offline — responses will sync when you reconnect.

Installable as a PWA

Each form generates its own PWA manifest dynamically — using the form title, theme color, and URL. Add it to the home screen for a native app-like experience without app stores.

One toggle to enable

Enable offline mode per form in the editor settings. A privacy notice reminds you that form structure will be cached on respondents' devices. Disable anytime to revoke caching.

Smart payment guard

Forms with payment fields detect the missing connection and show a clear message — no silent failures. Non-payment fields in the same form still work offline.

Automatic form updates

When the device reconnects, the cached form definition is compared against the latest version. If you've published changes, respondents see the updated form on their next visit — no manual refresh needed.

Your competitors can't do this

Most form builders require a constant internet connection. formcel is the only platform that lets your forms work completely offline with automatic background sync — no native app required.
