Signing in to Field on your phone

Sign-in is something you meet on your first day, again when you switch phones, and now and then when the app asks for it out of the blue. Here is how it works and why, and what signing out does to the work sitting on the phone.

Getting the app on the phone

The shop arranges installation with us, so if Field isn't on your phone yet, ask your manager rather than hunting for it. Your manager also sets up your account in Office and will tell you which email to use. It's a work Google account, so there's no separate BoltWright password to keep track of.

The first sign-in

Open Field and start the sign-in. The app sends you to a browser page, you sign in there with the work Google account your manager told you to use, and once Google is satisfied you land back in the app. The detour through the browser is there so that Field never sees your Google password.

The email has to match the one your manager gave you. If you sign in with a personal account, or one left over from a previous shop, Google will let you in and BoltWright won't.

You stay signed in

Day to day you don't sign in again; you open the app and you're in. A session does end after 30 days without using the app, or after 90 days total, and then Field asks you to sign in once more with the same account. Your work is still on the phone when that happens, so it costs you a minute of the morning and nothing else.

The other way a session ends is the office turning off your access, in which case the app locks on the phone. That's the office's decision, not a glitch, so if it happens and you didn't expect it, talk to your manager rather than trying to sign in again.

When the sign-in lapses in a basement

The awkward case is the session expiring while the phone has no signal, because the app can't check with the office and can't ask you to sign in either. Field keeps your workspace open when that happens. Everything you've saved stays saved, and you can keep taking notes, photos and readings on the stops the phone already prepared. What pauses is syncing, anything that would change a record on the office side, and Bolt; if you happen to be on a voice call with Bolt at that moment, the call ends. The office can't see any of that work until you're back in range and signed in, so if your manager is waiting on a report, it's worth a phone call to say so.

Once you have signal, sign in again with the same account and the queue picks up where it left off. Signing in as someone else won't pick up that work, because the phone keeps each person's work separate on purpose.

Signing out

Signing out is the one action that removes work from the phone, which is why the app doesn't make it easy to do by accident. When you sign out, Field tells you exactly how many drafts and captures haven't reached the office yet, and it defaults to cancelling. If you confirm anyway, that account's data comes off the phone: cached stops, units, notes, photos and the queue. Anything the office had already received is safe in Office, and anything it hadn't is gone.

So don't sign out to fix a sync problem. If the queue isn't moving, open the app on a good connection and give it a minute, or call the office and tell them what's on the phone.

Ten phones, and the laptop

A person can have Field signed in on up to ten phones at once. When an eleventh signs in, the phone that signed in longest ago gets signed out, which keeps a phone forgotten in a drawer from staying signed in forever. If you replace your phone, sign in on the new one and carry on. Signing out on the old one first is tidier, but only once its queue is empty.

Field in a browser on a laptop uses the same work Google account and gives you the same access, so a manager who moves between the truck and the desk has one account for both.
