Field app

The offline installer app — the one thing a web app can’t fake

Native · iOS + Android

Built for a wet field with no signal

Incumbent field apps are cut-down web views that fall over the moment a crew loses signal (app-store 1.9–2.9★). Fettle’s installer app is offline-first: the whole job pack lives on the phone, work continues all day, and everything syncs — photos, readings, batches, signatures — when a bar comes back.

Job pack — gated, can’t skip a step

Offline-first

Full job pack cached on device. Crews work all day in a field with no signal; edits queue and sync the moment a bar returns.

Gated job packs

Can’t skip a step. RAMS sign-off unlocks photos, photos unlock the form — compliance is the path, not a reminder.

Geotagged photos

Every before/after shot carries GPS + timestamp, straight onto the site diary and the auto-drafted case study.

Batch scan

Scan resin, hardener and EPDM batch numbers on site — the traceability line that backs every 1177 test cert.

Sync engineReady

Conflict-free background sync. When Crew B rejoins signal, 1 queued change — photos, readings and the signed job pack — upload in order, and the office liveboard updates in seconds.
