Watermark Camera helps contractors, inspectors, cleaners, property managers, maintenance crews, and other field professionals document work on site. Capture, stamp, organize, compare, and export on your iPhone, without an account or advertising. CAPTURE WITH CONTEXT See the stamp while framing a photo or video. Switch cameras, use the grid and timer, pinch or select a zoom level, and control the rear torch. Video mode offers supported 1080p or 4K resolution and 30 or 60 FPS, with safe capability fallback. BUILD YOUR FIELD STAMP Apply one of seven field-work layouts or customize a reusable template. Add local date and time, time zone, address, Decimal, DMS, UTM, or MGRS coordinates, GPS accuracy, altitude, heading, project, client, job number, worker, and note. Adjust position, size, opacity, seconds, and 24-hour time. Live captures use the available date and GPS snapshot at capture time; the app does not let you rewrite them. Missing date or location stays unavailable instead of being replaced with invented values. ORGANIZE EACH JOB Create local projects for sites, clients, or work orders while keeping originals and stamped results separate. Browse saved media, search notes or locations, and mark captures as Before or After. Drag a merged comparison separator or switch to side-by-side viewing. The internal gallery opens the latest saved result without leaving the app. EXPORT PROFESSIONAL RECORDS Export a Before/After record in the format your workflow needs: • PDF with stamped records and project details • CSV metadata for spreadsheets and job systems • KML location data for mapping tools • ZIP with stamped media, PDF, CSV, KML, and manifest.json Each stored original and stamped result receives a SHA-256 checksum. The manifest records provenance, available capture metadata, paths, and checksums. This integrity check can reveal file changes; it is not independent verification of time, GPS, or authorship and does not make a file tamper-proof. LOCAL-FIRST AND OFFLINE Projects, indexes, media, and exports are managed locally. Capture works offline. Address lookup and optional system services are best-effort and never replace the core workflow. Camera access enables capture, location adds optional GPS fields, microphone records video sound, and Photos access is used only when importing or saving media. You choose visible fields and whether to add results to Photos. WATERMARK CAMERA PLUS Create ten successfully saved stamped photos free across all projects. Failed or canceled attempts do not use this lifetime installation allowance. Plus unlocks unlimited stamped photos, stamped video, reports, custom-format exports, and batch archives. The paywall shows both plans, prices, trial eligibility, and Restore Purchases. Watermark Camera is documentation software, not a certification authority.

Timestamp Camera stamps the time, date, location and weather into your photo at the moment you take it — not afterwards, and not from memory. What you see in the viewfinder is what lands in the file. BUILT FOR FIELD WORK · Construction and inspection — keep the task, the place and the day's conditions in one photo · Equipment handover and acceptance — a clear record at delivery, fewer follow-up questions · Field service — roofs, bridges, or well outside town: open it and shoot · Everyday work logs and travel notes WHAT IT DOES · Live watermark — time, date, weekday, GPS coordinates, address and weather, all visible in the viewfinder before you shoot · Photo and video — video watermarks are burned into the frame, not pasted on afterwards · Two site templates — dark "Work record" for harsh light, light "Field capture" for everyday delivery · Your own logo — upload a brand logo and put it on every shot · Manual fields — project name, notes and anything else you fill in yourself · Capture history — every shot is saved to your library and logged for later review · Verification — check a photo against its capture record · Works offline — shoot without a signal; records upload themselves once you are back online · English and Chinese, and it scales up to iPad PERMISSIONS · Camera — taking photos and video · Location (while in use) — showing where the shot was taken, and the weather there · Photo library — saving watermarked shots and picking a logo image · Microphone — recording audio with video The camera works without location access; the place and weather fields are simply left out.
