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.
One inspection app for inspectors and surveyors worldwide.
Whether you call it a home inspection app, property inspection software or a building survey tool — Blackslate is built for the job and the standards you work to.
Home inspectors (US & Canada)
InterNACHI- and ASHI-aligned templates, severity scoring and branded reports — a modern, affordable Spectora and HomeGauge alternative with no per-inspection fees.
Surveyors (UK & Ireland)
RICS Home Survey-style coverage with a dedicated damp and moisture section, moisture-meter readings and condition reporting buyers expect.
Building surveyors (DACH)
Mobile app for German property surveys (Hausgutachten) and pre-purchase inspections — InterNACHI/RICS/DIN coverage, EU hosting in Germany, GPS photos and PDF reports.
Snagging & handover (GCC)
Property handover and snagging inspections across the UAE, Saudi Arabia and the wider Gulf — offline-ready for new-build sites with no connectivity.
Solo & multi-inspector firms
Start solo, add inspectors as you grow. Shared dashboard, scheduling and custom branding on the Studio plan.
Pre-purchase & move-in checks
Pre-purchase home inspections, move-in/move-out condition reports and periodic property checks — all from one checklist app.
From front door to finished report.
Three steps. Five minutes the first time, two after that.
Pick property & start
Add the property and open an inspection across 16 SoP-aligned sections — exterior, roof, structure, electrical, plumbing, heating, damp and more.
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.
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.
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.
Immediate risk. Exposed wiring, missing GFCI/RCD, structural movement — surfaced at the top of the report summary.
Significant defect. Roof covering failure, active leaks, foundation cracks — needs attention and budget.
Lower-cost repair. Sealant, trim, cosmetic-to-functional issues worth noting.
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.
