Timemark alternatives
Timemark alternatives: timestamp camera vs. sealed proof
Why do people look for a Timemark alternative?
Usually not because the app is bad at its job. The common reasons are seat cost as a crew grows, wanting photos to live inside the system that already runs the work, or — the one this page is really about — reaching a moment where a stamped photo stopped being enough for the person disputing it.
What does Timemark actually do well?
It is a good timestamp camera and it is simple, which is most of the value. It stamps a time and GPS onto the shot as you take it, keeps photos organized by project in a shared cloud workspace, works offline and syncs later, and exports to PDF, Excel, ZIP or KMZ. Its published authenticity claim is a verified timestamp and GPS location on every photo, backed by a unique photo code. And it keeps broadening: time-tracking and checklist features are shipped, there is an interactive demo, a restoration case study, more free tools beside the verification center, and nine language versions (as of 2026-08-28).
How is Timestamp It different from Timemark?
They start from the same idea — a camera that stamps time and GPS onto the shot — and each has grown its own way. Timestamp It describes batch job documentation, PDF reports for clients, a public verify path and trust page, and vertical pages for construction, private investigation, real estate, and property management; its site claims “Trusted by 700K+ field pros,” and Pro is listed at $9.99/month (as of 2026-08-28). Timemark’s own breadth is described above. Both are stamp-first cameras; which fits you comes down to the workflows around the camera.
What does a sealed record add to a timestamp on the photo?
Three things. The time is written by the server when the submission arrives, rather than taken from the sender. Capture is live-camera-only, with the gallery closed. And the image and that server-set time are sealed together under one SHA-256 fingerprint — with the coordinates too, when the worker shares location — so a later change to any of them is detectable. A stamp on the image settles most ordinary questions without any of that, and Timemark goes further than a stamp: it operates a public Photo Verification Center where a photo code can be checked (as of 2026-08-05).
Is LockProof a Timemark replacement, or something you run alongside it?
Either, and the honest answer depends on volume. If most photos are for coordination and only some jobs get disputed, keep the camera app and add LockProof on the jobs that carry money. If the whole reason you adopted a timestamp camera was disputes, LockProof replaces it rather than layering on, because a verified record already covers what the stamp was doing.
How do the prices compare?
Timemark publishes Plus at $5/user/month and Business at $7/user/month, with Enterprise listed as coming soon (as of 2026-08-04). LockProof starts at $99/month for Essentials, with Professional from $399/month. They are not the same shape of product, so the per-seat comparison flatters whichever one you already prefer — the useful question is how much one disputed job costs you.
The five options, and who each one is for
1. LockProof — best for the job that gets argued about
The category-different answer: not a camera app, the verification layer. The worker taps a link in a text, with nothing to install and no account to manage. The link opens the camera and the gallery stays blocked, so a file chosen from a roll cannot enter. The server writes the time when the submission arrives, GPS goes on the record when the worker shares location, and the image, the coordinates and that time are sealed together with a SHA-256 hash, so a later change to any of them stops matching. From $99/month (Essentials); Professional from $399/month, as of July 2026. See how it works on a jobsite.
2. Timestamp It — best for batch job documentation with client PDF reports from a timestamp camera
A timestamp and GPS camera that has grown into a jobs product: batch job documentation, PDF reports for clients, a public verify path and trust page, and vertical pages for construction, private investigation, real estate, and property management. Its site claims “Trusted by 700K+ field pros.” Pro is listed at $9.99/month, as of August 28, 2026. See timestampitapp.com.
3. CompanyCam — best for a fuller photo platform once one camera app stops being enough
A jobsite photo app that captures photos and auto-organizes them by project, with team collaboration, AI photo annotations, and 60+ integrations. No tamper-evidence or chain-of-custody claim is published on the pages we checked. Core at $63/month (1 user, then $29/additional user), Crew at $129/month, Scale at $199/month, and a custom Enterprise plan, as of July 2026. See companycam.com.
4. SiteCam — best for pinning photos onto floor plans and tracking change over time
A construction photo app that pins photos to plans and maps with automatic GPS and timestamp, building a timeline of change across a project. No explicit tamper-evidence claim is published on the pages we checked. Pricing was not published where we looked — SiteCam offers a free account and directs you to sign up, as of July 2026. See sitecam.io.
5. Raken — best for auto-generated PDF daily reports from the field
Construction daily-reporting and field-management software: daily reports, time tracking, and safety and quality checklists, with auto-generated PDF daily reports. No tamper-evidence claim is published on the pages we checked. Pricing was not published where we looked — Raken offers a free trial and directs you to a demo, as of July 2026. See rakenapp.com.
What a sealed record does
Both products put a time on a photo. A sealed record moves three inputs out of the sender’s hands: the server writes the time when the submission arrives, the gallery stays closed so only a live photo can enter, and the seal itself is not drawn onto the picture — it is a SHA-256 fingerprint over the image bytes and that server-set time, plus the coordinates when the worker shares location, stored with the record. Change any one of those inputs afterwards and the fingerprint stops matching, which is what makes a later edit detectable rather than merely discouraged. On everything else a camera app is simpler, cheaper per seat, and faster to roll out.
The same photo, 170 times
This is not our argument. Writing in Claims Journal on 3 May 2023, an insurance digital-forensics practitioner, Shane A. Riedman, set out how insurers screen claim photos across four threat vectors: metadata inconsistencies, image duplication, internet sourcing, and pixel manipulation. The example that carries the point is duplication — a single property appraiser used the same photo across 170 different claims over two years, on claims totalling more than $1 million in indemnity payments.
Notice the two separate questions in that story: when a shot was taken, and whether that same shot has been attached to something else already. A LockProof record is its own live capture, filed against one job, so each one stands on its own rather than being re-attachable to another claim.
Be precise about the other approach, because the honest version is narrower than the marketing version. A LockProof record is a live capture with the gallery closed, so the record itself cannot be a pre-existing file dropped into place — a different starting point from a library of images that can be copied onward. It is not a defence against duplication in general: nothing here governs what someone does with a record after it leaves, it does not stop a screen or a printout being re-photographed, and it cannot vouch that the scene in front of the lens is what it appears to be. What it changes is narrow and checkable — each record is its own live capture carrying a time nobody on the sending side chose, sealed so that a later change to it stops matching.
If your photos mostly answer “what did we do last Tuesday”, a timestamp camera is the right tool and you should keep it. If they occasionally have to answer “prove it” to someone with money at stake, that is a different question, and it is worth reading how to prove a photo is real before the argument rather than during it.
