Half the places a tradie works are the places a phone gives up. Underfloor. Plant rooms. Lift shafts. A shed forty minutes past the last tower. Most job apps handle that badly, because they are websites in a costume: no signal, no app.
What happens when the signal drops
Yamate installs to your home screen and runs from your phone. The whole app is on the device, so it opens and works the same with the signal off:
- Quote a job — line items, your saved prices, GST, the lot.
- Raise an invoice — including the invoice number, which never repeats itself.
- Add customers and jobs, edit them, mark them done.
- Take photos of the work — they're stored on the phone, not uploaded on the spot.
- Read anything you've already got — every job, every customer, every past invoice.
None of that is queued or half-done. It is written on the phone the moment you tap, the same way a note app writes a note.
What syncs, and when
Cloud backup is optional and off until you turn it on. With it on, your work syncs in the background whenever you have a connection — you don't press anything, and you don't wait on a screen.
| Where you are | What Yamate does |
|---|---|
| No signal | Everything saves on the phone. You keep working. |
| Back in range | Your changes go up in the background, and anything from your other device comes down. |
| Two devices, both edited | The newer edit wins, field by field — not "last one to open the app wipes the other". |
The honest limits — what does need a connection
Some things send to somebody else, so they cannot happen with the signal off. They wait, and you send them when you're back:
- Texting a customer — a quote, an invoice or a payment reminder has to leave your phone to reach theirs.
- Card payments — the payment link and the card charge both run through your payment provider.
- Anything that looks something up — an ABN lookup, or an AI-drafted quote.
- Syncing itself, and sharing a job with a customer.
The work is still done and saved. It is the sending that waits.
Why this is the difference on site
An app that stalls with no signal costs you the one moment when quoting is easy — standing in front of the job, with the customer next to you. Do it there and the price is right and the job is usually won. Do it at 9pm from memory and it's a guess, and half the time it never gets sent at all.

Does Yamate really work with no internet?
Yes. Quoting, invoicing, jobs, customers and photos all work with the signal off, because the app runs on your phone rather than on a website you have to reach. Sending a text or taking a card payment needs a connection, because those leave your phone.
Will I lose anything if my phone drops out mid-job?
No. Your work is written to the phone as you go, not held in a browser tab waiting to be submitted.
Do I need to press sync when I'm back in range?
No. If you've turned cloud backup on, it syncs in the background on its own.
Does it work on both iPhone and Android?
Yes — the same app on both. You install it to your home screen from the website; there's no app-store download.
Where is my data if I never turn cloud backup on?
On your device. Cloud features are opt-in, so nothing syncs until you switch backup on — and if you do, that's what lets you move to a new phone without losing your books.
