Shashin-ban is a camera app for construction sites that lets you document work just by shooting in order. It automatically creates an electronic site board (the green "kokuban") and burns it into every photo — no more writing boards by hand. Simple enough for anyone on site, including older workers and non-Japanese crews. How it works • Pick the type of work and the spots — boards are generated automatically • On-screen and voice guidance shows what's next; just shoot in order • The board is added to each photo automatically, so nothing is missed Features • Auto-generated site boards (green board / white board / clear band styles) • Drag to move and resize the board; many ready-made layouts • "Before" shot added automatically; "After" too when the site covers the last step • Shoot without a board too (for wide or situational photos) • Easy retakes; auto-advance to the next shot • Keep and switch between multiple sites • Photos organized by site and by spot, with keyword search • Also saves to your phone's Photos app (on/off) • Auto-landscape while shooting • 6 languages: Japanese, English, Chinese, Vietnamese, Korean, Indonesian • Send a site's setup (places, steps, board) via LINE etc.; the receiver shoots with the same board • Fix a board's place/step after shooting (a correction record is kept and shown in the ledger) Private by design • All photos and data stay on your device. No account, no cloud upload. Please note • Not compatible with the tamper detection (J-COMSIA authenticity check) required for digital site boards on Japanese public works. Intended for private projects and internal records. Site photos, made simple.
