Everything your crews need in one platform

From the moment your team arrives on site to the final closeout delivery, Mastlens handles every step.

Photo Documentation

Every photo is automatically stamped with GPS coordinates and timestamps. No more guessing where or when a shot was taken. EXIF data is extracted and stored for full auditability.

Structured Checklists

Build reusable checklist templates with sections and fields tailored to your tower installation process. Track completion progress in real time across your entire team.

One-Click Closeout Packages

Generate professional closeout packages with a single click. All photos, checklists, and documentation are compiled into a branded ZIP file ready to deliver to your client.

Three steps to a complete closeout

Replace scattered photo folders, email chains, and spreadsheets with a streamlined workflow your whole team can follow.

1

Capture

Your field crew opens Mastlens on any device and snaps photos at the tower site. Each photo is automatically tagged with GPS coordinates, timestamps, and linked to the right project and checklist field. Works even without cell service.

2

Organize

Photos flow into structured checklists with predefined sections and fields. Managers can track progress in real time, see which items are complete, and identify what is still outstanding across all active projects.

3

Deliver

When the project is complete, generate a professional closeout package with one click. All photos, checklists, and metadata are compiled into a branded, downloadable ZIP file ready to send to your client or general contractor.

Built for the field, refined for the office

Every feature is designed with input from real tower installation crews and project managers who live this workflow every day.

Offline Support

Tower sites often lack cell service. Mastlens works fully offline as a Progressive Web App. Photos and data sync automatically when your crew is back in range.

GPS & Timestamps

Every photo is automatically embedded with precise GPS coordinates and capture time. Prove exactly where and when documentation was taken for full compliance.

Team Management

Assign crew members to projects, create user groups by trade or region, and control who can see, edit, or submit closeout documentation with role-based permissions.

Checklist Templates

Create reusable templates for different tower types and installation procedures. Standardize your documentation process across every job site and every crew.

Photo Organization

Photos are automatically organized by project, checklist, and section. Filter, search, and browse your entire documentation library with ease.

Closeout Packages

Generate branded, professional closeout packages ready for client delivery. All documentation is compiled into a downloadable ZIP with structured folders and metadata.
