What is the difference between Apex Sketch and iGUIDE?

Apex Sketch and iGUIDE are different tools with different strengths. The best choice depends on your workflow, budget, and whether you need features like 3D scanning, floor plan generation, GLA calculation, or design capabilities. This page breaks down a direct comparison.

Which is better for real estate appraisers — Apex Sketch or iGUIDE?

Apex Sketch and Iguide serve different workflows. Apex Sketch is better suited for one use case while Iguide fits another — the right choice depends on whether you need field capture or office-based GLA calculation from existing floor plans.

Can Apex Sketch and iGUIDE be used together?

Apex Sketch and Iguide can complement each other in some workflows — for example, using one for field capture and the other for GLA calculation and reporting. Check the comparison table above for specific integration details.

How much does Apex Sketch cost compared to iGUIDE?

Apex Sketch and iGUIDE have different pricing models — one may charge per user, per project, or via annual subscription, while the other may offer a free tier or pay-per-use option. Check the comparison table above for current pricing details and which offers better value for your volume of work.

Which is easier to use — Apex Sketch or iGUIDE?

Ease of use depends on your starting point. Apex Sketch tends to fit one type of user or workflow, while iGUIDE is designed for another. If you are working from an existing floor plan PDF and need to calculate square footage quickly, a browser-based tool like PlanSnapper may reduce the learning curve entirely — no software installation required.

Do I need Apex Sketch or iGUIDE if I already have a floor plan PDF?

If you already have a floor plan as a PDF or image, you may not need either tool. PlanSnapper lets you upload the PDF directly and trace walls in your browser to calculate GLA — no software installation required. Both Apex Sketch and iGUIDE are most useful for creating sketches from scratch or capturing measurements in the field.

Which works better for calculating GLA — Apex Sketch or iGUIDE?

Both Apex Sketch and iGUIDE can support GLA calculation, but the workflow differs. One may require field measurement and sketch entry while the other may allow importing existing floor plans. If your starting point is an existing PDF or image floor plan, PlanSnapper provides a faster path — upload, trace, and get the GLA figure without entering either tool's workflow.

Does iGUIDE produce ANSI Z765 compliant GLA figures?

iGUIDE can produce ANSI Z765-compliant GLA measurements, but the appraiser must verify that the correct above-grade, finished, heated-space definitions are applied. iGUIDE captures all interior space by default, so the appraiser needs to confirm that garages, unfinished areas, and below-grade space are properly excluded before treating the figure as compliant GLA.

What do appraisers do with an iGUIDE floor plan in their workflow?

Appraisers who receive an iGUIDE floor plan typically verify it meets ANSI Z765 requirements, then either enter the measurements into their sketch software (like Apex Sketch) or upload the PDF to a tool like PlanSnapper to trace and confirm the GLA independently. Using the iGUIDE data as a starting point can save field time, but the appraiser remains responsible for the reported GLA.

Apex Sketch vs iGUIDE: Which Is Better for Appraisers?

Apex Sketch and iGUIDE both produce ANSI-compliant floor plans for residential appraisers — but they represent completely different workflows. One is software you sketch in after the fact; the other is hardware you carry to the property. Here is how they compare on cost, accuracy, and day-to-day practicality.

The short version

Apex Sketch: Best for appraisers who take their own field measurements and prefer a dedicated desktop sketching tool that integrates with AMC and appraisal software.
iGUIDE: Best for appraisers who want to capture the floor plan on-site automatically and skip the back-office sketching step entirely.

Apex Sketch vs iGUIDE: at a glance

	Apex Sketch	iGUIDE
Type	Desktop sketching software	Hardware camera + cloud processing
Floor plan input	Manual sketch from your measurements	Automated on-site laser capture
ANSI GLA	Yes (core feature)	Yes (included)
Appraisal software integration	Yes (ACI, a la mode, TOTAL)	PDF/XML export — no direct plug-in
Time to floor plan	15–30 min (sketch after field visit)	2–4 hours (cloud processing)
Upfront cost	None (software only)	~$3,000–$5,000 for the camera
Ongoing cost	~$20–$30/mo subscription	$14–$18/scan (varies by plan)
Accuracy	Depends on your measurements	±1% (laser-based)
Best for	Appraisers comfortable sketching	High-volume or premium service appraisers

Workflow comparison

With Apex Sketch, your workflow stays the same as it always has: take your own measurements on-site (tape, laser measure, or Disto), then sketch them in the desktop app back at your office or in your car. The software handles area calculations, GLA separation, and export to your AMC form.

With iGUIDE, you set up the camera in each room and let it spin. After the appointment, upload to the cloud and wait 2–4 hours for the processed floor plan. You still need to review and verify the output before signing off — but the measuring step is eliminated entirely.

Cost reality check

Apex Sketch is effectively free to start — you likely already have measuring tools. At ~$20–30/mo, the software cost is negligible for a full-time appraiser.

iGUIDE requires a $3,000–$5,000 hardware investment upfront, plus $14–18 per scan. At 15 appraisals per month, that is $210–270/mo in scan fees alone. For a high-volume appraiser or one who charges a premium for 3D tours, the ROI can work. For the average solo appraiser doing 8–10/mo, it is a harder sell.

ANSI compliance

Both tools produce ANSI Z765-compliant floor plans with correct GLA separation and below-grade reporting. Apex Sketch has been the industry standard for this for decades. iGUIDE matches it but requires verification that finished areas were captured correctly — especially in split-level or complex homes where the camera may miss a room.

When to choose Apex Sketch

You already measure properties yourself and want a better sketching tool
You need direct integration with a la mode TOTAL or ACI
You want low overhead with predictable monthly costs
Your volume does not justify a $4,000 hardware investment

When to choose iGUIDE

You are doing 20+ appraisals per month and time per inspection is a real constraint
You want to offer 3D tours or interactive floor plans as an add-on service
You are building a team and need consistent, person-independent output
Your clients or AMCs have started requesting digital deliverables beyond PDFs

The PlanSnapper angle

Neither tool helps if you already have the floor plan and just need to calculate GLA from it. If a client sends you a PDF floor plan, or if you have a sketch that needs square footage verified, that is where PlanSnapper fits: upload the plan, trace the outline, and get a defensible GLA number in minutes — no hardware, no subscription to another platform.
