ProofCam feature guides
One guide per feature: what it does, how to turn it on, which plan includes it and how it differs on Android and iPhone. Grouped by area.
Capture
Watermark Templates: 6 Styles, Custom Fields and Date Formats
Design your photo stamp in ProofCam: 6 watermark styles, 10 ready-made templates, custom fields, date formats, 6 positions, logo, map and template sharing.
Document Scanning with Photo Codes and On-Device OCR
Scan multi-page forms into one PDF with a Photo Code on every page, read serial numbers with on-device OCR and shoot in low light with Night/HDR.
Construction Photo Documentation: A Practical Field Guide
Pin photos on floor plans, shoot compass-guided 4-direction sets, import 360° photos and turn site photos into daily reports and diaries with ProofCam.
Field Meters, RTK GNSS and Laser Readings on Your Photos
Stamp light, sound and vibration readings on site photos, connect a Bluetooth RTK GNSS receiver or laser meter, and know the limits of phone meters.
Blurry Photo Detection: Dark and Overexposed Shot Alerts
ProofCam checks each photo right after capture and warns if it looks blurry, too dark, overexposed or tilted, so you can retake it before leaving the site.
Camera with Level and Compass: Tilt, Pitch, True North
Use your phone's sensors as a camera level, inclinometer and true-north compass. ProofCam stamps the bearing on the photo and saves pitch and roll as evidence.
Timestamp Video: GPS Watermark Video with SRT and GPX
Record timestamp video with a GPS watermark and a Photo Code, pause and resume in one file, and export per-second time and location as SRT and GPX files.
Construction Time-Lapse from a Phone: Interval Shooting
Shoot a construction time-lapse on your phone: interval photos every 3 s to 1 h, each stamped with its own Photo Code, then build an MP4 on the phone.
UTM and MGRS Coordinates on Photos: DMS, Plus Code, Bearing
Print UTM and MGRS coordinates on photos, or decimal degrees, DMS and Plus Codes, and stamp the distance and true bearing to a target point.
Floor Level on Photos from Your Phone's Barometer
Stamp an estimated floor level on photos from the phone barometer: set a reference floor, read Floor ~N (±1), and learn why the altitude line is GPS.
Proof & trust

Every ProofCam photo carries a Photo Code. Learn the 3, 4 and 14-character formats and how to check a photo on the web or offline in the app.
Network Time vs. Phone Clock: Why Your Photo Stamp Can Be Trusted
Changing the phone clock doesn't change a ProofCam stamp. See how network and satellite time work, and how photos are flagged when time isn't confirmed.
GPS Address, Accuracy and Location Trust Grade on Photos
How ProofCam turns GPS into an address on your photo, shows accuracy, handles manual addresses and grades location trust from A to D on Android and iPhone.
Fake GPS Detection: Stop Mock Location Clock-Ins
How ProofCam flags fake GPS and mock location apps, rooted phones and off-site photos, and how team policies can lock the clock-in button.
Screen Recapture Detection and Live Proof Photos
ProofCam warns when a photo looks like a shot of a screen or a print, and Live proof keeps a short clip around each photo. How both work.
