Sample location mapping, material assessments, and regulatory-compliant inspection reports.
Energy Auditors
Room-by-room area calculations, wall surface measurements, and thermal inspection documentation.
Insurance Adjusters
Property damage documentation, claim evidence, and detailed loss assessment floor plans.
From site to report in minutes
Three steps. No laptop required. Everything happens on your phone.
Sketch the layout
Walk the site and draw walls, doors, and rooms. The snap engine keeps everything aligned and measured.
Run the inspection
Place observation pins, take photos, record audio notes. Use custom templates to capture exactly the data you need.
Generate the report
Tap export and get a professional PDF with floor plans, observations, photos, and area breakdowns. Share the report with clients or invite colleagues to collaborate on the plan.
Everything you need in the field
From first sketch to final report, MasterPlan handles the entire inspection workflow so you can focus on the job.
Precision Drawing
Sketch walls, place doors and stairs, add custom objects. Snap engine aligns walls at 45° and 90° angles with real-world measurements.
PDF Reports
Generate professional reports with floor plan images, observation details, photo evidence, and area breakdowns. Rooms are grouped by building with envelope data included. Edit and annotate before sharing.
Observation Pins
Drop pins on your floor plan for each inspection point. Attach photos, audio notes, and custom field data. Track status with color-coded indicators.
Voice Dictation
Record audio notes and let the on-device Whisper engine transcribe them to text. Multiple model sizes for the right speed-accuracy trade-off.
Area Detection
Tap any enclosed room to compute floor area and perimeter instantly, with wall thickness deducted for true net area. Add wall height and openings for net wall surface area. Group rooms into building envelopes for outer perimeter and total wall area at a glance.
Share & Collaborate
Send plans to clients for review, invite colleagues to co-edit, or share finished reports. Real-time edit locking and version conflict resolution (keep mine, theirs, or both) prevent lost work. Archive synced plans to free up device storage.
