About
Fathom ONE is the all-in-one field tool for contractors, designers, and remodelers. Capture precise room scans, communicate with clients in real time, and keep every project organized from the first site visit to final delivery.
ROOM SCAN
Turn any iPhone or iPad with a LiDAR Scanner into a professional measurement tool. Fathom ONE captures accurate 3D room data in minutes and converts it into:
• Floor plan PDFs formatted and ready to share or print
• High-resolution PNG floor plans for presentations, InDesign layouts, or email
• DXF files optimized for Chief Architect, 2020 Design, KCD Software, and AutoCAD
• USDZ 3D models, viewable in AR on any iPhone or iPad
Every exported floor plan includes room dimensions, door and window locations, floor area, and a scale bar. Tap any dimension to correct it with your tape measurement. Export once, use in any software.
CAD READY EXPORTS
No manual cleanup required. Fathom ONE's export presets are purpose-built for the tools you already use:
Chief Architect: inches, 3D walls, CAD-to-Walls format, with door and window openings and a window and door schedule
2020 Design: inches, 2D plan, angle-corrected centerlines
KCD Software: inches, 2D room layout
AutoCAD / Generic DXF: configurable to your preferred settings
THE LOOP
Keep clients informed without the back-and-forth. The Loop is a built-in messaging channel attached to each project, so conversations stay organized by job, not buried in text threads. Each project's daily logs are one tap away.
Clients can log in from their own device to view updates, ask questions, and submit room scans directly from their home, no app expertise required.
DAILY LOGS
Document every day in the field with structured logs that include weather conditions, progress notes, inspection records, and milestone tracking. Attach photos directly from your camera roll. Every log is timestamped and stored by project.
PROJECT DASHBOARD
See your active projects, recent estimates, and permits at a glance, plus any punch items assigned to you. Jump into any project's Loop, scans, or logs in one tap.
BUILT FOR THE FIELD
Fathom ONE is designed for how contractors actually work: fast to open, easy to hand to a client, and room scans save offline and upload when you're back in range. No learning curve, no unnecessary features.
Download Fathom ONE and spend less time measuring, more time building.

React in the Loop - Press and hold a message to react with a thumbs up, a party popper or a question mark. Tap a reaction to add or remove your own, and press and hold it to see who reacted. Daily logs - Tapping a daily log notification now opens that job's daily logs, instead of just the project list. Fixes - An appointment outcome recorded earlier is no longer cleared when a lead is edited.
