Timemark: Photo Proof solves a problem familiar to anyone working out in the field: a photo gets taken, but there’s no reliable way to prove exactly when and where it was captured once a client or inspector starts asking questions. Rather than being just another camera app that stamps a date on a photo, Timemark focuses on producing work evidence that’s genuinely hard to fake.
Overview of Timemark: Photo Proof
The app is developed by OG Co., has passed 10 million downloads on Google Play, and is used by teams in construction, fiber optic, cable and telecom, HVAC, property management, cleaning, and security as a way to document field work. Every photo taken through Timemark carries a timestamp and GPS coordinates backed by anti-tamper technology, along with a unique photo code developed by Timemark for tracing the original capture time and location if it’s ever disputed. The company reports the app is trusted by millions of field professionals and teams across these industries.
Gameplay
When shooting through Timemark, the app auto-names photos using the timestamp plus a custom note, which keeps hundreds of job-site photos from turning into an unsorted mess. Photos save and sync to the cloud instantly with no extra steps, and importantly for anyone working in areas with weak signal, the app can still capture GPS data without an internet connection, then upload automatically once the device reconnects.
Team Collaboration System
For projects involving multiple people, Timemark offers a shared workspace called Teamspace, where the whole crew’s photos sync automatically into one place instead of everyone texting photos to be sorted manually later. Photos can be organized by project, client, or location, and shared through direct links so clients or inspectors can view them without installing anything. Role-based permissions mean each team member only sees the projects relevant to them, which matters once a company is juggling several active job sites at once.
Standout Features
On the reporting side, photos can be exported as KMZ files to view on a map in Google Earth, or as PDF, Excel, or ZIP files formatted to match whatever a client or government body requires. Timemark: Photo Proof also supports before-and-after comparison layouts for inspections, along with a timesheet feature that calculates work hours based on photo history. The app offers a free tier with customizable watermark templates, plus Plus, Business, and Enterprise plans for individuals, teams, or larger organizations needing centralized management.
Tips for Using Timemark: Photo Proof
It helps to set up a separate project for each job site from the start rather than dumping every photo into one place, since filtering and exporting reports later goes much faster once photos are already sorted by project instead of mixed together after the fact. In areas with weak signal, it’s worth double-checking that location permission is granted before heading out, since offline photo capture still relies on GPS even though it doesn’t need mobile data to record a coordinate. For important inspections, using the before-and-after comparison layout tends to make a stronger case than attaching scattered individual photos when presenting to a client or inspector.
Conclusion
Overall, Timemark: Photo Proof suits individuals or teams who need reliable work evidence that holds up when disputes come up. Anti-tamper timestamps, offline capability, and flexible export formats are clear strengths for field work. For someone who just wants to take ordinary personal photos, the app may feel like overkill, but for anyone whose job depends on proving progress or job-site condition, it’s worth serious consideration.
