Built for the field

Home inspection software that does the paperwork for you.

Offline home inspection app

Basements, attics, empty properties with no signal. The app captures checklists, photos, GPS and the inspector's signature on-device and syncs the moment you're back online. Nothing is lost.

GPS-stamped photos & severity

Every photo is geo-tagged and timestamped at capture. Rate each finding Safety Hazard, Major, Minor or Monitor — the report summary writes itself and your evidence holds up for clients and disputes.

Branded inspection report

One tap produces a clean PDF in your branding and a secure client link (90-day expiry, no client login). The buyer reads the home inspection report on their phone before you've left the driveway.

How it works

From front door to finished report.

Three steps. Five minutes the first time, two after that.

1

Pick property & start

Add the property and open an inspection across 16 SoP-aligned sections — exterior, roof, structure, electrical, plumbing, heating, damp and more.

2

Inspect & photograph

Rate each item by severity and attach GPS-stamped photos as you walk. Works offline; the moisture & dampness section is built in for RICS-style condition reporting.

3

Sign & deliver

Sign on the device. One tap generates the branded PDF and a secure client link, and the report is archived with a full audit trail.

What is a home inspection app — and why switch from paper?

A home inspection app replaces paper checklists, a camera roll and a retyped report with one mobile workflow: standard-aligned checklists, photo evidence captured in place, and a branded report generated automatically. Blackslate is built specifically for residential inspection — not a generic form builder.

  • Hours back every job. The report is done when the walkthrough is done — no evening retyping from notes and a camera roll.
  • Evidence that holds up. GPS coordinates and timestamps on every photo prove what was inspected, where and when — for client disputes and your own protection.
  • Built for your standards. InterNACHI, ASHI and RICS coverage with DIN references — recognizable to certified inspectors and chartered surveyors.
  • Damp done right. A dedicated Moisture & Dampness section with moisture-meter readings — the part European and UK buyers care about most.
  • Nothing gets lost. Every inspection lives in one system, synced and exportable, and works offline until you're back in signal.
Coverage you can stand behind

16 sections, 110+ items, every one tagged to its standard.

Structured to align with the coverage of the leading residential Standards of Practice, so certified inspectors and chartered surveyors recognize the format.

InterNACHIASHIRICS Home SurveyDIN (DE)
Safety Hazard

Immediate risk. Exposed wiring, missing GFCI/RCD, structural movement — surfaced at the top of the report summary.

Major

Significant defect. Roof covering failure, active leaks, foundation cracks — needs attention and budget.

Minor

Lower-cost repair. Sealant, trim, cosmetic-to-functional issues worth noting.

Monitor

Keep an eye on it. Early-stage or seasonal items to re-check over time.

The sections cover the whole home

Exterior & site, roof & chimney, foundation & structure, attic / insulation / ventilation, electrical, plumbing, heating, cooling, kitchen, bathrooms, living areas, bedrooms, doors & windows, garage, basement / crawlspace, and a dedicated moisture & dampness section. Bathrooms and bedrooms repeat per room.

Blackslate is independently developed by Blackcarrot Tech and is not affiliated with or endorsed by InterNACHI, ASHI, RICS, ICC or DIN.
