Gas rate calculated on the phone, not on the back of a job sheet
Gas rating an appliance means timing the meter and doing arithmetic in a cupboard with a torch. Gaffer's calculator does the sum on your phone, so the figure that goes on the certificate is calculated rather than estimated.
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.
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.
- Available in the mobile app on site
- Works offline in meter cupboards and plant rooms
- Result recorded alongside combustion readings
- Feeds gas safety certificates and service records
- Part of the gas engineer and heating trade packs
- No separate app or conversion chart needed
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.
Gas rate calculator 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 →
What does gas rate calculator 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 gas rate calculator 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.
