No signal. No problem.
CrewBox assumes basements, remote sites, and dead zones. Where cloud-dependent photo apps stall without signal, CrewBox keeps capturing, creating, and commenting — and syncs itself when coverage returns.
Capture never stops
Photos and videos store locally with their tags, notes, and GPS. Browsing previously loaded projects and photos works from the on-device cache.
Projects born offline
Create a project at a greenfield site with no coverage and document all day. When signal returns, the project syncs first — then its photos follow automatically.
A sync engine that retries
A connectivity observer triggers sync the moment the network returns. Uploads run two at a time and failed transfers reset and retry on reconnect and app start.
Full visibility
The Upload Queue screen shows offline projects, in-flight uploads, pending drafts, and failures with per-item errors — plus Retry Failed and Clear controls.
