What Works Offline

What you and your crews can do with no signal in the field app, the Estimator and the CRM, and what waits until you're back online.

The short version

Crews can clock in, start phases, fill checklists, take photos and leave notes with no signal. The Estimator keeps measurements and site notes. The CRM keeps quick notes. Everything sends on its own when the phone gets signal back.

The same table is in the field app under Today, then Saved for offline, then "What works offline".

Everywhere

  • A line at the top (field app) or bottom left (Estimator, CRM) says when you’re offline and how many changes are waiting, with Retry.
  • Changes send on their own when the signal is back, every 20 seconds, and when you open the app.
  • Anything the office refuses stays on screen with Try again; nothing disappears silently.
  • On a shared phone or tablet, a different person signing in wipes the saved pages; their own waiting changes stay for them.

Put Peak on your home screen

Peak runs in your phone's browser, and you can add it to your home screen so it opens like an app. Crews add Peak Field from any field page. Owners add Peak from Basecamp.

  • iPhone (Safari): tap the Share button, then "Add to Home Screen".
  • Android (Chrome): open the menu (three dots), then "Add to Home screen" or "Install app".

Open each page you'll need once while you have signal. That's what saves it to the phone.

QUESTIONS

Common questions.

Changes are kept on the phone until they send, and notes are saved with every keystroke. When the phone comes back on and has signal, they send on their own.

Completing a phase checks the office's rules, like required photos and checklist items. That check needs a connection, so it waits for signal.
