Big Splash

Big Splash is an offline-first plant valve-tag book for process operators, turnaround crews, P&ID walk-down teams, and new unit trainees. Keep every field valve identity on one industrial face: tag number, service fluid, nominal size, normally-open or normally-closed state, and location path—without network or special device permissions. Cold start opens your active unit’s fullscreen tag book. Dense cards show tag ID, service, size, bold NO/NC chips, and multi-line location text—not a marketing carousel or empty shell. Flip NO/NC with one tap and high-contrast state color so walk-down crews read fail position at a glance. Edit any tag with a structured form for ID, service, size class, P&ID line reference, area/rack/elevation location, and optional isolation or lockout marks. Mint whole racks in one pass with bulk authoring: set prefix, start number, count, and shared service, size, and location defaults—then sequence or paste tags instead of entering them one by one. Organize a multi-unit plant shelf. Create units and areas, duplicate a unit skeleton, and keep separate tag books per process block. A seeded demo process unit ships ready with sample utility and process valves across two areas, plus empty-unit templates, so reviewers and trainees can build a full site book in minutes. Filter and search by tag substring, service fluid, size, NO-only or NC-only, lockout marks, and unit or area path. Export a plain-text or CSV-style tag sheet of the current filtered book through the system share sheet for shift printouts or mailbox handoff. Preferences restore your last-open unit on cold start and remember default size units, NO/NC chip theme, and sort order (tag, service, or location). All data stays on-device. No account. No cloud sync. Optional share export only when you initiate it. In-app Privacy Policy and Terms disclose on-device persistence and user-initiated export only.
