Sift & Screen replaces paper pre-starts, scattered spreadsheets, and missed service intervals with a professional, tablet-native platform that works in Airplane Mode.
Purpose-built for industrial operations — not adapted from generic field service software.
PowerSync SDK with encrypted SQLite. All writes are local-first. Data syncs atomically when connectivity returns — even on weak 3G.
PowerSync · sqlite3mcManagers or Servicemen can lock a machine from service. A full-screen red warning blocks operators from logging on tagged-out equipment.
Safety CriticalFull chain-of-custody from Master Tank → Fuel Truck → Machine Fill. Automatic inventory deduction. Live burn-rate reporting per machine.
ComplianceReal-time streaming speech transcription in the Service Notes field. Designed for gloved hands — no third-party API, no data leaves the device.
Native · On-DeviceTimed sample recording with live Tonnes Per Hour calculation. Role-gated to authorised reporters. Results sync to the manager dashboard in real time.
Aggregate ReportingClock-in / clock-out with live elapsed timer. Overtime auto-detection. Weekly review for workers. Full manager review via the web portal.
Payroll AccuracyStructured digital checklist with automated defect injection into service notes. Failed items are flagged and synced as urgent alerts.
WHS ComplianceFive report types generated locally — no server round-trip. Fleet, Maintenance, Fuel, Production, and Master Fleet reports shared via native OS share sheet.
No Connectivity NeededRevenueCat across Google Play and Apple IAP. Stripe on web. Subscription gating at the sync infrastructure layer — tamper-resistant by design.
RevenueCat · StripeEach user type gets a purpose-built interface and permission set — enforced from the moment they log in.
Machine operators on the site floor. Designed for high-contrast use on a dusty tablet, with or without connectivity.
Mechanics and technicians who maintain the fleet. Fast access to service data and machine status across all assets.
Business owners and site managers with full administrative control — via the mobile app or the web portal from any browser.
A Flutter mobile app and a Next.js web portal sharing a single Supabase cloud backend — connected by the PowerSync offline sync engine.
Multi-tenant isolation, end-to-end encryption, and Australian Consumer Law compliance — built in from day one.
The on-device SQLite database is encrypted using sqlite3mc. Encryption keys are stored in OS-native secure storage (EncryptedSharedPreferences on Android, Keychain on iOS).
Data isolation between companies is enforced by PowerSync's sync_rules.yaml — server-side, before any data leaves the cloud. Devices physically never receive rows from other tenants.
Before issuing backend tokens, the platform verifies the app binary is genuine and unmodified, running on non-compromised hardware, distributed through official channels.
Managers use Supabase cloud auth. Workers log in offline with a SHA-256 hashed 4-digit PIN verified against the local database — zero network requests, instantaneous, secure.
Monetisation enforcement is at the infrastructure layer — the get-powersync-token Edge Function validates subscription status before issuing any sync token. Cannot be bypassed client-side.
Privacy Policy (Australian Privacy Principles), Terms of Service (non-excludable statutory guarantees), and Heavy Machinery Safety Disclaimer — all maintained under JH Software Solutions.
