Mastlens

Capture GPS and time-stamped job-site photos, run structured checklists, and keep tower closeout documentation moving — even where there's no signal. Description Mastlens is the field documentation app for telecom tower crews. Capture the proof your closeout package needs — right at the site, even with zero signal — and let the paperwork build itself while you work. BUILT FOR TOWER WORK • Every photo is automatically stamped with GPS coordinates and time, so your documentation holds up • Structured checklists mirror your company's closeout requirements — no more guessing which shots are missing • See exactly what's done and what's left before you leave the site, and skip the costly return trips WORKS OFFLINE Tower sites rarely have good coverage. Mastlens stores photos and checklist progress on the device and syncs automatically when you're back in range. FROM SITE TO CLOSEOUT Everything you capture syncs to the Mastlens platform, where your back office assembles polished, client-ready closeout packages — organized by project, checklist, and section. FOR TEAMS • Projects and checklists assigned to your crew show up ready to work • Managers see field progress as it syncs • Role-based access keeps everyone in their lane Mastlens is built for telecom tower installation and maintenance companies. An account provided by your company is required to sign in — ask your Mastlens administrator for an invitation.
