About

Space Inspector

Features
Read full description

Space Inspector is the definitive digital tool designed specifically for U.S. Navy Sailors, Division Officers, and Department Heads (Not Endorsed by the US NAVY) to streamline shipboard zone inspections. Ditch the clipboard, stop losing track of handwritten notes, and manage your divisional spaces directly from your iPhone or iPad. Built for the reality of shipboard environments, Space Inspector allows you to document discrepancies (hits), track accountability, and generate professional reports for your chain of command in seconds. KEY FEATURES: LOG & TRACK DISCREPANCIES Quickly record hits with essential details including issue title, specific location, corrective action, and priority level. Assign standard Navy categories and load pre-built requirements to standardize your divisional tracking. PHOTO EVIDENCE & ANNOTATION Take photos of discrepancies right in the app using a specialized low-light camera mode tailored for dark engineering and auxiliary spaces. Add instant red-circle markups and annotations to highlight exactly what needs fixing. TRUE OFFLINE P2P SYNC Shipboard Wi-Fi is non-existent when you need it most. Space Inspector uses local peer-to-peer network technology to sync your entire inspection database with other devices in your division. Share manifests and transfer payload updates completely offline without needing a router or internet connection. INSTANT PDF PUNCHLISTS Generate comprehensive Divisional Master Punchlists with a single tap. The app automatically paginates and organizes your hits by space, category, and priority into a professional vector PDF. Export Image Reports or accountability lists to print or AirDrop directly to your Chief or Leading Petty Officer. ACCOUNTABILITY & TRACKING Assign POICs (Petty Officer in Charge) to specific hits or entire spaces. Track CSMP Job Numbers, monitor correction status, log who corrected the issue, and attach proof-of-correction photos so nothing falls through the cracks before the next zone inspection. DIVISIONAL DASHBOARD Get a top-down view of your spaces with the built-in analytics dashboard to instantly see open hits, priority breakdowns, and overall readiness. Whether you are a Division Officer preparing for INSURV, a Work Center Supervisor managing weekly maintenance checks, or a Safety Officer ensuring compliance, Space Inspector brings modern accountability to the deckplates.
