Paperless quality checklists that auto-flag out-of-spec and raise the defect.
LeanOS is digital quality-checklist and inspection software for manufacturing. Build templates once, capture runs on mobile with instrument and batch traceability, and any out-of-tolerance reading is re-checked on the server and auto-raises a defect. Audit-ready by default, and free to pilot for 30 days.
Paper checklists fail the moment a reading is out of spec.
- ✕Out-of-tolerance readings get written down — and quietly ignored.
- ✕No link between a measurement and the gauge that took it.
- ✕Batch / lot traceability lives in someone's memory, not a record.
- ✕A 'required' check can be left blank and nobody notices until the audit.
- ✕Audit prep means photocopying binders and hoping nothing's missing.
Inspection capture that protects the audit trail.
Spec to signed-off run in five steps.
- 1Build the templateDefine items, tolerances, required instruments, and whether a batch reference is mandatory.
- 2Run it on mobileThe operator captures readings on the floor, picking the instrument and batch where required.
- 3Out-of-spec auto-flagsThe server re-checks tolerances and flags anything out of bounds — no client trust.
- 4Defect raisedAn out-of-tolerance reading raises a finding automatically and routes it for action.
- 5Verify and exportA co-signer verifies where needed, and the signed run exports clean for any audit.
Questions plant teams ask
What is a digital / paperless checklist app?
It replaces paper inspection and quality checklists with a mobile tool that captures readings, enforces tolerances and required fields, and stores a tamper-resistant record. LeanOS adds server-side out-of-tolerance re-checks, instrument-calibration gating, and auto-defect creation.
Does it support IATF 16949 / FSSC traceability?
Yes. Batch / lot references, instrument calibration links, signatures, and required-item enforcement give you the traceability and audit trail those standards expect — and runs export cleanly for the auditor.
What happens when a reading is out of tolerance?
The server re-verifies the reading against the template's stored bounds and automatically raises a defect, so an out-of-spec result can't be recorded as acceptable or quietly skipped.
Can checklists be filled offline?
Yes — runs are captured on mobile and sync when the device reconnects, so plant dead-zones don't block inspection.
How much does it cost?
LeanOS starts with a free 30-day pilot — no credit card. We scope pricing with you when you're ready to roll out.
