Field Measure was designed by a licensed general contractor who got tired of clipboards, lost notes, and measurement errors. Built for contractors, installers, window & door dealers, and homeowners who need accurate measurement logging done fast.
Log complete window and door specs on the job site and export professional PDF reports to share with suppliers and clients.
Capture handing, glass type, dimension type, and assembly details accurately — everything your supplier needs to fulfill the order correctly.
Send field reps out with a standardized measurement tool. Get back complete, organized specs ready for quoting and ordering.
Measuring for a window or door replacement? Walk into any supplier or contractor meeting with a complete, professional measurement report — and know exactly what you need.
No unnecessary complexity. Every field is there for a reason — because a working contractor designed it that way. Log a complete window or door entry in under 30 seconds.
Log width, height, quantity, style, handing, glass type, dimension type, and assembly — all from one clean form designed for speed in the field.
Export a complete contractor report with all entries, photos, specs, and notes. Ready to share with suppliers, installers, or clients on the spot.
Attach job site photos directly to each measurement entry — from your camera or photo library. Stays organized with the measurement, not in a separate folder.
Every project saves automatically. Browse, reopen, edit, and re-export past jobs. Your measurement history is always with you.
Data syncs silently to iCloud. If you get a new phone, your entire measurement history comes with you. No accounts, no setup.
No internet required. Works in basements, remote sites, anywhere with no signal. Take measurements wherever the job takes you.
Field Measure captures the full picture for windows and doors — the information your suppliers and installers actually need.
Dark UI, large touch targets, amber accents. Easy to read in direct sunlight, easy to use with work gloves on.
