Biometric login

Face ID and fingerprint.

Replaces a clipboard, a camera roll and a job sheet in the footwell. Paperwork gets done while the job is still in front of the engineer, not reconstructed at 6pm.

Why it matters

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.

What you get
  • Sign in with a fingerprint or face unlock instead of typing a password on a ladder
  • Tokens are held in the device's secure storage, not in a text file
  • Optional two-factor authentication on top for the office accounts
  • Sessions can be revoked centrally if a phone is lost
Where it fits

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.

Biometric login is one part of that step. The rest of the job — quoting, scheduling, certificates, invoicing and payment — runs in the same system, on the same record. See the whole job →

About biometric login

Something else? support@rungaffer.com

What does biometric login replace?

For most trade businesses, a clipboard, a camera roll and a job sheet in the footwell. Paperwork gets done while the job is still in front of the engineer, not reconstructed at 6pm.

Does biometric login work on a phone, and offline?

Yes. The mobile app is offline-first: records created on site are stored on the device and synced automatically, in order, when signal returns. Lofts, plant rooms and rural sites were the design brief.

Which plan is it on?

Every paid plan. Biometric login is included for unlimited users at no extra cost — the monthly, annual and lifetime plans differ only in how you pay.
