Real-Time Fatigue Monitoring built to ensure your workers are fit for duty.

Fatigue management software like FatigueGuard gives safety-critical employers a real-time view of workforce fatigue risk before and during shifts. Workers complete a 75-second pre-shift assessment on their iOS device — combining the Karolinska Sleepiness Scale (KSS) subjective rating, the Samn-Perelli operational fatigue scale, and an objective Psychomotor Vigilance Test (PVT) reaction-time test. The platform aggregates those signals into a composite fatigue score, surfaces HIGH and MODERATE risk workers on a supervisor dashboard, triggers instant alerts, and generates audit-ready compliance reports aligned to NHVR accreditation, HVNL 2026 SMS requirements, and WHS obligations. The result: organisations in mining, transport, construction, healthcare, and FIFO operations get the documentation and visibility they need to demonstrate duty of care without deploying any specialist hardware.

Yes. FatigueGuard is designed from the ground up to satisfy National Heavy Vehicle Regulator (NHVR) accreditation requirements and the HVNL 2026 Safety Management System (SMS) reforms. Every pre-trip fatigue assessment, supervisor alert, and resolution action is automatically logged to an immutable audit trail. At any time you can export a fully formatted PDF compliance report covering an individual driver or your entire fleet for any date range — one click, no manual collation. The report structure maps directly to NHVR audit checklists, covering fatigue monitoring records, corrective action evidence, and Chain of Responsibility (CoR) documentation that proves each party in the supply chain met their duty of care.

Before each shift begins, the worker opens the FatigueGuard iOS app and completes a three-part assessment that takes approximately 75 seconds. First, they rate their current sleepiness on the Karolinska Sleepiness Scale (KSS) — a validated 1-to-9 scale where 7 or above indicates high fatigue risk (Kaida et al., 2006). Next, they rate their operational fatigue on the Samn-Perelli scale — a 7-point measure validated in mining, aviation, and military contexts. Finally, they perform a short Psychomotor Vigilance Test (PVT) — tapping the screen whenever a stimulus appears — which measures reaction time as an objective indicator of alertness; a mobile PVT correlates at r = 0.77 with the laboratory standard (Visuri et al., 2025). FatigueGuard's scoring engine combines all three inputs into a single composite risk rating (LOW, MODERATE, or HIGH). If the rating is MODERATE or HIGH, the worker's supervisor is immediately notified via push notification or email so they can intervene before the shift starts.

Any industry where fatigue can cause serious injury or death is required or strongly advised to implement a formal fatigue management plan. In Australia this currently includes: road transport and logistics (HVNL and NHVR accreditation requirements); mining and resources (state-based mine safety Acts and FIFO/DIDO shift work exposure); construction (WHS psychosocial hazard obligations, including Victoria's 2025 OHS Psychological Health Regulations); healthcare (hospital credentialing standards and roster policies for clinical staff working extended shifts); emergency services; and aviation ground operations. Chain of Responsibility (CoR) legislation extends fatigue obligations beyond just the driver or worker to schedulers, loaders, operators, and executives — meaning the entire supply chain benefits from documented, auditable fatigue monitoring. FatigueGuard serves all of these sectors from a single platform.

Yes — FatigueGuard is a pure software solution. Workers only need the iOS app on their existing smartphone; there are no EEG caps, camera-based eye-tracking devices, steering-wheel sensors, or wearable biosensors to procure, maintain, or replace. Starting from $5.96 per worker per month, it is a fraction of the cost of hardware-dependent fatigue detection systems, with no procurement lead time and no ongoing maintenance contracts. The app-based KSS, Samn-Perelli, and PVT assessments are each independently validated in peer-reviewed research to detect fatigue without hardware. For organisations that already use wearables for other purposes, FatigueGuard can ingest that data alongside its own assessments — but wearables are never a prerequisite.

Most organisations are fully operational within two business days. Because FatigueGuard requires no hardware procurement, no server installation, and no complex IT integration, the implementation process is straightforward: Day 1 covers organisation setup, site configuration, and supervisor dashboard training; Day 2 covers worker onboarding — workers download the iOS app, register with their existing work email or an invitation link, and complete a guided orientation assessment. Roster imports and alert threshold configuration can be completed by an administrator without vendor involvement. For enterprise deployments with custom SSO, Clerk-based directory sync, or API integration into an existing HRIS or fleet management system, allow five to ten business days. There are no hardware procurement delays and no on-site installation visits required.

The Karolinska Sleepiness Scale (KSS) is a validated, nine-point subjective sleepiness measure developed at the Karolinska Institute in Sweden and widely used in occupational fatigue research and clinical sleep medicine. Respondents rate their current level of sleepiness from 1 ("Extremely alert") through to 9 ("Extremely sleepy — fighting sleep, effort to keep awake"). Scores of 7 or above are considered high-risk in safety-critical contexts and trigger an elevated fatigue classification within FatigueGuard. Research shows KSS correlates with the EEG gold standard at r = 0.56 (Kaida et al., 2006). The KSS takes approximately 10 seconds to complete. In FatigueGuard it is combined with the Samn-Perelli scale and objective PVT reaction time results to form a composite score, reducing the influence of subjective bias and improving classification accuracy compared to self-report alone.

The Heavy Vehicle National Law (HVNL) 2026 reforms require transport operators to implement and document a Safety Management System (SMS) that demonstrates proactive fatigue risk management — moving beyond basic hours-of-service records to evidence-based monitoring and continuous improvement. FatigueGuard automates the documentation burden of these requirements. Every pre-trip fatigue assessment generates a timestamped, immutable record. Supervisor interventions, corrective actions, and near-miss events are logged automatically. The platform's compliance engine maps your records to the SMS documentation framework required for NHVR accreditation, and generates the required audit reports on demand. Chain of Responsibility (CoR) evidence — proving schedulers, operators, and consignors each took reasonable steps to prevent fatigue-related risk — is captured as a natural by-product of using FatigueGuard. Operators who adopt FatigueGuard before the HVNL reforms take effect will have a defensible, documented compliance history from day one.
