Mobile App

How to confirm a pre-start landed on the record, read a machine's logbook in the app, and what it means when a check is invalidated.

The full pre-start walkthrough — finding the machine, working the checklist, defects on the way through, spotter confirmation, and the unlock.

Every way to reach a machine's record in the app — scanning, browsing, recent equipment — and exactly why a machine might not appear.

What the PreStartGo mobile app needs from a phone — hardware, permissions, sign-in — and how app updates and version enforcement work.

What happens when a safety-critical pre-start item fails, and how the two controlled bypass paths work when a failed machine still needs to move.

What the app can and cannot do with no signal — the cached data, the signed offline unlock, the pending queue, and how everything syncs back.
