Does it work without signal?

Open your day once while you have signal and today's stops stay readable on that phone: each job's checklist, notes, files, timer and the customer sign-off. With no signal you can still tick the checklist, add a note, take a photo, attach a file, start and stop the timer, and take the customer's sign-off. Each one is saved on the phone first, marked "sends with signal", and sent once — never twice — when signal returns, in the order you did them. If the office changed something meanwhile, the latest version is shown and the app says so; anything that can't be saved says why and offers Retry. A sign-off is recorded only against the version of the job the customer saw. Nothing that moves money happens without signal: invoices, payments, expenses and logging hours all wait until you're back online. Photos of earlier visits need signal to load.
