The whole system on the engineer’s phone
Android (iOS coming soon), 220+ screens.
Part of field & mobile in Gaffer, which replaces a clipboard, a camera roll and a job sheet in the footwell.
Where the app is. The Android app is in closed testing, not on the public Play Store yet — email us at sign-up and you are on the tester list the same day. On iPhone the whole system runs in Safari today; the native app is next.
A field app that works in the basement, the loft and the middle of nowhere.
Offline-first on Android, with iOS to follow. Jobs, forms, photos, signatures and clock-ins are captured on the device and synced the moment signal returns.
Paperwork happens on site, while the job is in front of the engineer — not reconstructed in the van at 6pm.
Native mobile app is one of the 7 things in field & mobile. See the rest →
- The full system on the phone, not a cut-down viewer of the web app
- Today’s route, the job, the certificate, the photos, the signature and the invoice
- Works offline and syncs when signal returns, in the order the work actually happened
- Engineers see only their own jobs; the office sees everything
Step 04 of the job: on site
The engineer taps “On my way” and the customer gets a text with an arrival window. On site: clock in, photos, the certificate for the job — EICR, Gas Safety, whatever the trade needs — signed on the device. No signal? It syncs later.
Field & Mobile is where native mobile app sits, and that is the step it shows up in most. The rest of the job — quoting, scheduling, certificates, invoicing and payment — runs in the same system, on the same record. See the whole job →

What is native mobile app for?
The full system on the phone, not a cut-down viewer of the web app Today’s route, the job, the certificate, the photos, the signature and the invoice
Which phones does it run on?
Android today — the app is in testing on the Play Store. iOS is coming; until it lands, an iPhone user has the full web app, which works in a phone browser.
What happens to work done with no signal?
It is saved on the device and sent when signal returns, strictly in the order it happened. If one item fails the queue stops rather than skipping it, so nothing is quietly lost.
Which plan is it on?
Every paid plan. Native mobile app is included for unlimited users at no extra cost — the monthly, annual and lifetime plans differ only in how you pay.
