Mobile App & Offline Sync
Maximizing the utility of the Proof field app in disconnected environments.
The Proof Mobile App is built to keep working reliably in the chaotic environments typical of property disasters, including areas with no signal.
The Offline-First Architecture
Basements usually don’t have cellular service. When a technician enters a subterranean environment, the app seamlessly transitions into Offline Mode.
- Vision AI Scans: Photos and scans are captured and cached locally on the device.
- Moisture Readings: Psychrometric inputs are logged to an encrypted local SQLite instance.
- Evidence & Notes: Job photos, readings, and notes are queued offline and attached to the job on sync. (Contract e-signatures require a connection — the app prompts the homeowner to sign once signal returns.)
Background Synchronization
The moment the technician walks up the stairs and hits an LTE or WiFi signal, the Backbone Sync Protocol initiates. Without any human intervention, the app:
- Pushes pending scan payloads and captured evidence to the Proof AI processing queue.
- Synchronizes local state with the Master Ledger.
- Pulls down any updated routing instructions from the Dispatcher.
This keeps field data from getting stranded on a device, and technicians don’t have to remember to hit a “Sync” button.
