What is the difference between Apex Sketch and CubiCasa?

Apex Sketch and CubiCasa 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 CubiCasa?

Apex Sketch and Cubicasa serve different workflows. Apex Sketch is better suited for one use case while Cubicasa 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 CubiCasa be used together?

Apex Sketch and Cubicasa 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 CubiCasa?

Apex Sketch and CubiCasa 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 CubiCasa?

Ease of use depends on your starting point. Apex Sketch tends to fit one type of user or workflow, while CubiCasa 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 CubiCasa 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 CubiCasa are most useful for creating sketches from scratch or capturing measurements in the field.

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

Both Apex Sketch and CubiCasa 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 CubiCasa require a smartphone scan, or can you use an existing floor plan?

CubiCasa is primarily a scan-to-floor-plan service — a technician or agent scans the property with a smartphone, and CubiCasa generates the floor plan from that scan. If you already have a floor plan PDF from a builder, prior appraisal, or another source, Apex Sketch or a browser-based tool like PlanSnapper is a more direct path to GLA without commissioning a new scan.

Can Apex Sketch produce the same deliverables as CubiCasa?

Apex Sketch produces appraisal-ready floor plan sketches with GLA calculations that meet ANSI Z765 and Fannie Mae requirements. CubiCasa produces visually polished marketing floor plans and can generate ANSI-compliant measurements when configured correctly. Apex Sketch output is optimized for appraisal report forms; CubiCasa output is typically used for MLS listings and property marketing.

Apex Sketch vs CubiCasa: Which Is Better for Appraisers?

Apex Sketch has been the appraiser's go-to floor plan sketching tool for decades. CubiCasa is a newer smartphone app that automates floor plan capture on-site. Both produce ANSI-compliant floor plans — but their workflows, costs, and tradeoffs are very different.

The short version

Apex Sketch: Best for appraisers who sketch from their own field measurements and want a desktop tool that integrates with appraisal software (ACI, a la mode, etc.).
CubiCasa: Best for appraisers who want to capture the floor plan on-site with a phone and skip manual sketching entirely.

Apex Sketch vs CubiCasa: at a glance

	Apex Sketch	CubiCasa
Platform	Windows desktop (+ mobile companion)	iOS / Android smartphone
Floor plan input	Manual sketch from your measurements	Automated walk-through scan
ANSI GLA	Yes (core feature)	Yes (add-on)
Appraisal software integration	Yes (ACI, a la mode, etc.)	PDF/DXF export only
Time to floor plan	15–30 min (sketch from measurements)	1–2 hours (cloud processing)
Pricing	~$20–$30/mo subscription	$4–$9/scan + GLA add-on

How Apex Sketch works

Apex Sketch is a Windows-based sketching application built specifically for real estate appraisers. You enter your field measurements — wall lengths, room dimensions — and Apex draws the floor plan to scale. It automatically calculates GLA according to ANSI Z765 standards, flags non-conforming areas, and handles complex scenarios like split-levels, attached garages, and finished basements.

Apex integrates directly with major appraisal report software including ACI, a la mode (WinTOTAL/TOTAL), and others. You can embed the completed sketch directly into your appraisal report without any file conversion. It is the industry standard for a reason — the workflow is optimized for how appraisers actually work.

How CubiCasa works

CubiCasa captures the floor plan in the field using your smartphone's camera. You walk through the property holding your phone, and the app's AI processes the footage into a to-scale 2D floor plan within 1–2 hours. There is no manual sketching involved — the floor plan is generated automatically from the scan.

CubiCasa's ANSI GLA add-on provides a certified square footage report alongside the floor plan. The output is a PDF that can be attached to an appraisal report. It does not integrate directly with appraisal report software the way Apex Sketch does.

Accuracy

Apex Sketch is only as accurate as the measurements you enter. If your field measurements are precise, Apex Sketch produces a perfectly accurate floor plan. If you measure incorrectly or miss a dimension, that error carries through to the GLA calculation. Accuracy depends on the appraiser.

CubiCasa's AI-based capture is accurate to approximately 1–3% for standard residential layouts. It removes human measurement error from the equation, but introduces AI interpretation error — complex spaces with alcoves, bump-outs, or unusual geometries can cause issues.

Workflow fit

For appraisers embedded in the traditional workflow — measure in the field, sketch at the desk, export to ACI or TOTAL — Apex Sketch is the dominant tool and offers the smoothest integration. CubiCasa requires a workflow change: you trust the AI scan instead of your own measurements, and you add a waiting period for cloud processing.

CubiCasa makes the most sense for appraisers doing high volume who want to eliminate time spent sketching, or for those who want a second verification of their manual measurements.

Already have the floor plan?

If you have a floor plan from Apex Sketch, CubiCasa, or any other source and need to verify the GLA calculation or measure a specific area, PlanSnapper lets you upload the image or PDF and trace the perimeter directly. No software integration required — just upload and measure.
