PlanSnapper vs iGuide: Which Floor Plan Tool Is Right for Appraisers?
iGuide and PlanSnapper are both used in real estate appraisal — but they solve different problems. iGuide captures precise floor plans on-site using a 360° camera and LiDAR sensor. PlanSnapper measures and calculates GLA from a floor plan you already have. Knowing which problem you actually have will tell you which tool (or both) belongs in your workflow.
The short version
- iGuide: Best when you need to capture a highly accurate, to-scale floor plan on-site. Requires the iGuide hardware kit.
- PlanSnapper: Best when you already have a floor plan — from iGuide, a builder, MLS, or elsewhere — and need to calculate or verify GLA without sketching software.

|---|---|---|
| What it does | Measures GLA from existing floor plans | Captures new floor plans on-site via LiDAR |
| Hardware required | Any device with a browser | iGuide camera + sensor kit (~$2,500+) |
| On-site presence | Not required | Required |
| ANSI GLA | Yes — trace and calculate | Yes — included in appraisal tier |
| Accuracy | Depends on source plan quality | ± 1% LiDAR accuracy |
| Turnaround | Real-time (trace as you go) | Minutes after upload (cloud processing) |
| Per-use cost | ~$9/month or day pass | $12–$25/scan + equipment amortized |
| Best for | Desk review, verification, existing plans | Field capture requiring high precision |
What iGuide does
iGuide is a hardware-plus-software system that creates highly accurate 2D floor plans and 3D virtual tours from a property visit. You mount the iGuide sensor on a 360° camera, photograph each room from multiple positions, and upload to the iGuide cloud. The system generates a to-scale floor plan with LiDAR precision — typically within 1% of actual measurements.
The appraisal tier includes ANSI-compliant GLA calculations. iGuide is popular among appraisers, agents, and home stagers who need the most accurate field-captured floor plans available without manual laser measurements.
What PlanSnapper does
PlanSnapper is a browser-based tool for measuring GLA from an existing floor plan. You upload any PDF or image, set the scale using a known dimension on the plan, and trace the outline of each area. PlanSnapper calculates square footage instantly and separates above-grade from below-grade areas for ANSI-compliant GLA reporting.
PlanSnapper does not capture floor plans in the field — you need an existing plan to start. But it works with plans from any source: iGuide exports, builder blueprints, MLS attachments, county records, or prior appraisals.
When you need iGuide
iGuide is the right call when you are on-site and need the most accurate possible floor plan capture. If the property lacks a usable existing plan, the MLS data is unreliable, or your client demands a defensible as-built measurement with LiDAR backing, iGuide delivers. It is especially strong for complex floor plans, multilevel homes, and properties where tape-measure sketching would be time-consuming.
The upfront hardware cost ($2,500–$4,000 depending on camera) means iGuide makes the most sense for appraisers doing high volume or serving markets that justify premium deliverables.
When you need PlanSnapper
PlanSnapper is the right call when you already have a floor plan and need GLA fast. Common use cases: verifying a builder's stated square footage, calculating GLA from an iGuide export without paying for the appraisal-tier upgrade, reviewing a prior appraisal for a desktop review, or double-checking an agent's listed square footage before signing off.
At $9/month with no hardware requirement, PlanSnapper is the lowest-friction option when the floor plan already exists.
Can you use both?
Yes — and it is a common combination. Capture the floor plan with iGuide in the field. Export the floor plan as a PDF. Upload to PlanSnapper to trace and calculate GLA at your desk, bypassing the iGuide appraisal-tier fee. You get iGuide's precision capture plus direct control over how GLA is calculated without paying twice for the same work.
The bottom line
If you need to create a floor plan from scratch in the field, iGuide is one of the best tools available. If you already have a floor plan and need GLA calculated quickly and accurately, PlanSnapper is the simpler, lower-cost option. Most high-volume appraisers will find value in having both.
