Everything it takes to turn site photos into a finished closeout
Mastlens is purpose-built for telecom tower installation crews. Capture GPS-stamped photos against structured checklists — even with no signal — and deliver a polished closeout package in one click.
One click turns your checklists into a finished closeout package
When the work is done, Mastlens compiles every photo into a clean, structured ZIP — a folder for each checklist, files named by section and field, and an auto-generated manifest summarizing completion. You get a secure link to send straight to your GC or carrier.
- A folder for every checklist; files named by section and field
- Auto-generated manifest with per-field completion and photo counts

Built for the way tower crews actually work
From the first photo on site to the final closeout, every feature removes a step between your crew and a delivered package.
GPS & time-stamped photos
Every photo is automatically tagged with GPS coordinates and a timestamp — burned in at capture and verified server-side from EXIF — so where and when is never in question.
Structured checklists
Organize work into checklists, sections, and fields. Attach reference images so crews know exactly what to shoot, and watch completion update in real time.
Works offline
Tower sites have no signal. Capture photos and complete checklists fully offline — everything queues on-device and syncs automatically the moment you are back in range.
Reusable templates
Spin up a project in seconds from your company templates or carrier-specific platform templates — your standard process applied the same way, every time.
JHA safety reports
Generate Job Hazard Analysis reports with a site map, nearest-hospital route, and optional fall-protection and driving-safety add-ons — ready to sign and share.
Map & project tracking
See every project on a map by status and location, search by address, and track completion percentage across all your sites at a glance.
Team roles & groups
Invite your crew, assign projects to people or groups, and control exactly what each person sees with admin, manager, standard, and restricted roles.
Photo gallery & recovery
Browse and filter every photo by date, person, or group, view full GPS and camera metadata, and restore anything from a 14-day trash window.
From the field to a finished package
Capture in the field
Crews shoot GPS- and time-stamped photos against your checklists — online or completely offline.
Organize automatically
Photos slot into the right checklist, section, and field as they sync, and progress updates in real time.
Deliver the closeout
One click bundles everything into a structured, shareable closeout package with a manifest.
